The Official B6 2.7T DIY/Swap Guide

[AudiTechS4]

? what are you guys doing for the lower rad hose. the b6 3.0 radiator i got ( 8E0121251C ) has the alignment slots at the top and bottom . on a s4 they are on the sides. trying to install is just kinking the line like crazy

Shave the index tabs on the radiator connection for the lower hose.

Wow I feel like an idiot. Thanks lol

You need to use the 3.0 lower hose with the 3.0 radiator.

[AudiTechS4]

3.0 exits down from the engine the s4 goes towards the fans

http://i1365.photobucket.com/albums/r757/t-die/TOBYDIE-PC/IMG-20130612-00262_zps78caace4.jpg

[MoparFreak69]

That's what my buddy used in his swap. The 3.0 is basically the same block except aluminum and not nearly as strong. Water pumps are the same, same goes with thermostat housing.

[AudiTechS4]

So he used the 3.0l thermostat housing then. I'm using the 2.7 aluminum one

[mauromj]

You need to use the 3.0 lower hose with the 3.0 radiator.

Just slice those slots of with a razor blade.

[MoparFreak69]

I guess you could always do it that way. I used a 2.8 radiator for a B5 A4 and the hose connected up like it belonged there.

[fR3ZNO]

Not overly surprising since the 2.8 and 2.7T are fairly similar.

[Carrture]

Was this question ever answered?

[AudiTechS4]

Ill get a pic for you today

[S4NIK8]

That's what my buddy used in his swap. The 3.0 is basically the same block except aluminum and not nearly as strong. Water pumps are the same, same goes with thermostat housing.

Assuming you're talking about the 2.8 thermostat housing here, the 3.0 part isn't even close to the same as the 2.7t

[Carrture]

I'm working on putting everything together for this swap and was wondering if anyone is running the B6 5 speed quattro trans. I currently have an 02 A4 trans with only 60K on it and was hoping I could use it without to much difficulty. I know I'll need the adapter plate, but do downpipes and everything else fit?

Was this question answered?

[AudiTechS4]

How does the 02a mount . Doesn't have side mounts on the subframe or the rear trans brace

[seanf86]

been following this for quite some time, has anyone ever done this with a tiptronic? if so what did you do for the shifter, since earlier cars had PRND432 and newer ones have PRNDS, I know there are tons of difference valve body and TCU p/ns so I would assume I'd need a tip trans from a 02+ a6 2.7 and TCU?

reason being my wife and I have lots of cars right now, I want to do this swap and downsize our fleet to maybe 2 cars and due to health reasons she can't drive a manual car anymore.

[ADCS]

Honestly, you are probably better off just buying a tiptronic 2.7t A6 or Allroad and driving it as-is.

[jesse500]

What difference will it make if the A6 is an automatic to mate it to my 6 speed?

anybody want to finish my project! smh 03 a4 cabby 3.0 swapped 0a3 drivline? pm me. my bm stole my engine

[wrcpulsar]

hi I have a 2003 b6 with a 2004 BES/BEL 2.7t engine init ,seemed to be running fine went out the other day and it started to chuck and jump around then no revs ,turnt it off restarts fine ,idles a little high at 1100 rpm but when u rev it wont go past 1700rpm,keep trying it and every so often it wil start and rev fine till u turn it off then it will just do the same ,no fault codes ,ive replaced coolant temp sensor,crank sensor and cam sensors ,I realy don't know what to do could it be throttle body I'm out of ideas

PLEASE HELP

[ADCS]

^I will start with the obvious, what codes are showing up when scanning with VCDS? Both MIL active and intermittent. And you will probably get better support in the B5 S4 or C5 A6 sub forums.

[RKLamb]

On the radiator hose I just got a hose off of a 2.8 Passat For some reason the angle was different, no bending.

This is the 2.8 hose I was talking about earlier. This and the B5 A4 with a 2.8 will fit right up like stock.

[a2goblueguy]

I'm connecting the 2.7T engine to the B6 A4 I have. Questions on exhaust. working off the following:
"The cheapest way to get it running would be SSAC downpipes, mated to a stock S4 catback (which has decent sized piping for stock and can be found from Free.3-$200). Keep in mind this will require some custom welding, but shouldn't cost much. "

Can I use the stock A4 downpipes and catback?

If no can I just use the B5 A4 catback and use custom downpipes? Is that were the custom welding mentioned above comes in?

Thanks,

Bill

[MoparFreak69]

No. the A4 never got the 2.7t, only the 2.8 (b5) and the 3.0 (b6). Neither will work without MAJOR mods.

[ADCS]

Does anyone know if the 3.0 and 1.8t rad/ac fans are the same? They look very similar to me. The smaller of the 2 fans from the 3.0 rad support/fan assembly I was planning to use sounds rough so I want to swap them. Looks like a bit of a pain to do so I figured I would ask before tackling it.

They are different but with only slight modifications the 1.8t fans fit on the 3.0 core support. Basically involves cutting off the bottom mount tabs and making your own.

Correct but the question wasn't about the S4, it was about the A4.

Hey guys, I have just managed to pick up a 2003 2.5tdi B6 6 speed manual with a blown motor that I would like to do the 2.7t Swap with, has anyone used a diesel car as a base for this swap as yet? Are there any extra issues that will arise due to it being a diesel? Any help and comments greatly appreciated.....

I would imagine the fuel system, like tank and pump are different.

[stugates]

I would imagine the fuel system, like tank and pump are different.

I think I would just be able to change over the fuel pump and the filter system to a petrol system. My main concern is the wiring, I think like anyone thinking about this swap, the motor swap and and problems that might arise in the install I am confident I will be able to manage....it's the wiring .....does anyone know if the base harness on the diesel is the same as that on a 3.0 or 1.8t?????

[MoparFreak69]

The car side of the harness is probably the same. The TDI engines utilize an ECU that functions very similar to the gas engines and has similar wiring. The fuel system shouldn't be much of a problem either. The plastic tank doesn't care what fuel is in it. The pump insert is probably the same as the gas engine setup, just a different pump for the different pressure and fuel configuration. The filter will need to be swapped anyway to get rid of the built in FPR and you need to add a return line anyway. Just blow the existing lines out to remove the majority of the diesel. You probably want to pick up a leak detection pump from a gas car for the proper ventilation setup for the tank. Nobody likes to smell gas fumes everywhere they go.

[Nollywood]

I can state from experience, the main wiring harness (dash / body connectors) is very different between a diesel and gasoline engine. You will have to do a heck of a lot of work, it would actually be easier to yank out the entire dash harness, and install a harness from a 1.8T / 3.0 of the same model year.

Fuel tank isn't a big deal, replace / install a regular gasoline fuel delivery unit, and the fuel lines, too. They are a fair bit fatter on a diesel-fed car.

how much different? You don't touch anything past the body plugs that connect to the engine.

[MoparFreak69]

I too am intrigued because everything from the firewall back is universal across the platform. People even run TDI clusters that have been recoded and had the faces swapped.

[Nollywood]

Very different. I'm speaking from experience.

I have converted a FWD B6 1.9 TDI 100 to a 1.8T 190 (BEX). There were enough differences between the body connectors, that it was easier to just swap in the gasoline harness.

I found the same differences in my 2000 B5 Quattro 2.5 V6 TDI, when I pulled the motor and harness.

[stugates]

Thanks for the info, We are a bit limited down here in South Africa to loads of spares and normally if you can find them they are quite expensive!!!! We also as far as I am aware never got the B5 S4 so I have to rely on Allroad's as my source of motor etc. I'm pretty sure that I will be able to find a dash harness from a petrol B6, was it a mission to swap that over? Can I use an Auto engine harness or must I locate a manual one?

[Nollywood]

You can use auto or manual, they're both the same.

That looks great, I have seriously been considering the single turbo route....do you have a build thread for yours? Did you use a kit or fab yourself?

I need to take some huge pointers from you man. that setup looks real clean, no messy wires in the way (almost as if you had wireless sensors...LOL) I even bought a spare harness so i can strip it and make them almost dissapear :). the single turbo setup is real neat, you did it right. now all you have to do is get rid of the ugly thing there that holds the coolant and use the small one from VW. it will just complete the look.

My 2.7 swap is finished... but it seems like the cooling fan is not working properly.... we wired a 2.7 fan module in, but the module stopped working two times now... Is this because I got a used fan module? Or there is a better way for the cooling fan?
Thxxx

[blitz2190]

the way i got my fans working at least for cooling was using 2 relays, one connected to each fan and triggered by the stock s4 temp switch. I had originally used another sourced switch but realized the same could be done with the stock one. heres a very crude drawing of what i did from my thread just use the s4 switch instead I don't have my diagrams currently as my computer had to be replaced and I need to pull my files form the old drive so you would need to find the sensor pinout of the s4 sensor you would run the ground to both switches in the s4 sensor where the bmw one had a common pin, ignore the condensor switch as I couldn't find a way to mount it, i ended up building a schmitt trigger based on the stock a4 pressure sensor to trigger it but that another story and more files in need to recover,

So a month or so ago I ordered some XS-downpipes for my friend's Allroad that I'm working on. They sent us the wrong ones and we went back and forth with emails and finally got the downpipes we needed last week. Today I get home and there's a big box at my door with Chinese lettering and return addresses and I was so confused. I don't remember ordering anything and I never get parts from China so immediately I think Fast and Furious and it's probably bomb! Anyway I open up the box and what's inside? 3" B5 S4 downpipes, the ones you order when you want to swap a 2.7 into a B6/B7. Is this even right? A free set of SSAC downpipes sitting at my door, and exactly the ones I want too... But not closely related to the previous Allroad downpipes they sent us. I'm convinced that this is a sign that my 2.7 swap is meant to happen [emoji23][emoji23][emoji23]

they will need to be modified if using the cross member to mount the transmission but yes those are the ones you would want for the swap. there is no direct bolt on solution for downpipes something will have to be fabricated or modified.

Hope you guys can help with a clutch flywheel question please. The 2.7t motor that I will be using is from a Auto so hence no flywheel and the B6 that I'm using is a 2.5 tdi....
What flywheel clutch setup would work and what would be best? Should I be looking at single or dual mass? Anyone with part numbers of what will work would be great

[ADCS]

You need a clutch/FW for the 2.7t
What to get depends on your mods, purpose of the car and future plans really. If you are staying with the K03 turbos than a B5 RS4 clutch would probably work for you. If you are going stage 3 you will need a clutch that can handle stage 3 power.

Personally, I wanted to retain the dual mass flywheel for a smoother stock like driveline. I really really really didn't want to deal with the chatter and harsh engagement of a lightweight FW or single mass. If you are building a track car you probably won't care about harshness. You can buy the OEM DMFW fairly cheap from Rock Auto (LuK DMFW which is the OEM manufacturer).

For the disc, again I wanted a smooth driveline so I only explored full face discs built similar to the OEM disc (sprung hub, marcel springs, etc). I choose Ringer Racing's full face ceramettalic disc/Cluth Masters pressure plate. It is full face, built well, good for 700ftlbs (crank) and doesn't break the bank.

Honestly these sorts of questions are better suited to the B5 S4 sub forum.

this is the setup i have for my stage 3 and there is no chatter and engages smooth, but like ADCS said it completely depends on what your going to run if you keeping the 2.7 in its stock form than this would be overkill
https://www.ecstuning.com/b-assembled-by-ecs-parts/stage-3-clutch-kit-with-lightweight-aluminum-flywheel-12lbs/b5s4s3ckfw/

the one thing I changed on that kit the last time I had the engine out was I tacked the bolts holding the steel ring on so they couldn't back out due to some others saying they could in the b5 forums.

[tankdeer]

This was being discussed elsewhere so I thought I'd ask here. Although not 2.7T specific, I ask because that is how it relates to our build. But does anybody know the actual torque limits of the 02x trans? I know it's not (theoretically) as strong as the 01e or 0a3. The self study claims it's only good for 330nm (~234 ft lbs). That seems incredible low, and I know people have to be pushing more, but how much more. Are we asking to grenade it at 400ft lb? 500?

Explains why mine's toast at 243 ft/lbs lol. I actually heard that the 02X is an updated version of the 01E. A lot of internal parts look similar except that 1-2 shift collar is built stronger on the 02X. I pretty much asked mec the same question and he said the 02X is built pretty strong. All the gears are forged and he said it could handle a pretty good amount of power as long as you don't miss-shift lol. I have big numbers planned for my 2.7 build and I plan to run the 02X transmission, but might have to swap to an 0A3 if I blow it up again.

According to the self study the 0a3 is actually an updated version of the 01e. The 02x is similar, but different http://www.volkspage.net/technik/ssp/ssp/SSP_325.pdf

The plans for the wife's avant as of now is SRM RS6 hyrbids with the stock 02x. If it blows, then upgrade to 0a3. I'm starting to wonder if at that level it's not "if" it blows but "when". A friend of mine has an 0a3 that I can probably get for cheap. I'm wondering if we should just go that route from the beginning.

So far all I've heard is similar to what you have. That the 02x is plenty strong, but not as strong as the 01e or 0a3. I'm basically wondering if anybody actually knows what "plenty strong" is. Martin is a smart guy be he's not the end-all on information, ha ha

[MurkyRivers_A4]

That read basically states the 0A3 is meant for applications with 350 or greater NM. 02X says up to 350 NM.

I would say the 0A3 would be the optimal application for a more than stock power 2.7T. Im sure the 02X would be fine, but for exactly how long....

Pat, if you take the 0A3, you can sell me your 02X and I will be a test mule on how long it will last :)

I'd still take an 02X over and 01E, but I'd take an 0A3 all day long. To give you an idea of 02X strength, there's a guy here that did a 2.7 (3.0 stroker) single turbo swap into a B7. It made 620whp. He ran it for close to a year I want to say until he shifted from 3rd to 4th and the 4th gear snapped when it got loaded up. A lot of people were saying it was just bad luck but still pretty impressive that transmission held those numbers with that kind of abuse for quite a while. He swapped in a RS4 tranny and sold the car after...

Right, the question is how accurate is that "guideline". People regularly exceed these recommended maximums. I'm curious about actual levels vs theoretical.

And yes, we can definitely work something out if we go that route

He ran it for close to a year I want to say until he shifted from 3rd to 4th and the 4th gear snapped when it got loaded up. A lot of people were saying it was just bad luck but still pretty impressive that transmission held those numbers with that kind of abuse for quite a while. He swapped in a RS4 tranny and sold the car after...
Interesting info, thanks for that. Does this guy have a build thread or anything?

[MurkyRivers_A4]

Right, the question is how accurate is that "guideline". People regularly exceed these recommended maximums. I'm curious about actual levels vs theoretical.

And yes, we can definitely work something out if we go that route

Well Im sure the guidelines can be exceeded and I think they are there for maximum life of the transmission and not necessarily the maximum torque that can be applied. The higher you go, the time it will last. Or something along those lines.

Just seems to me that the best choice would be to start out with the better rated transmission as it will only be stronger than the existing.

It will also make the whole swap easier as you can swap entire powertrains.

all luck of the gear lottery, some may hold some may not I've been running the O1E up until I ruined my engine. Held with a lot of abuse on stage 3 for a year, and planning to try and take it to 700whp now that I have built the the block so time will tell, I plan on going to the jhm kit when i blow the transmission.

Thanks. No problems, it has been fun. Your engine in the startup video sounds really strong. Listen to it over time to see if it goes away. Those tensioners can drain all their oil from sitting for awhile and the chains can be noisy for a bit when you start it up.

rattle or tick? I ask because when I had this issues thinking it was a tensioner it turned out to be a worn lobe on the camshaft which wore through the follower and caused the ticking. and the worn lobe on the exhaust cam is not uncommon. to add to nefkntym it could also be the followers needing to come up to pressure as well, mine were noticeably loud after replacing them due to no oil in them even with assembly lube for a minute.

[ADCS]

It was the power steering pump. I forgot to top it up after the initial cold fill up of the reservoir. It is still a but low (ran out of fluid) but as soon as I added some the noise reduced significantly. The engine is running really strong. Turns on effortlessly.

And the Ringer Racing stage 4 with full face cerametallic disc is super light and smooth. It is an easier pedal feel then the oem 1.8t clutch. So far I have only really driven it around on the driveway but I am liking it a lot.

the snub mount needs the 3.0 cross member for the radiator support our the whole cut wider to move the snub bracket on the support, once i get the front off my car I'll post a pic but that may be a while as I'm now 2 hours from my car. as for the downpipes if you use the transmission side mounts they fit but if you use the crossmember they will hit or have next to no clearance and will cause damage unless extended usually.

nope, all analog circuit, arduino's are greate but not ideal for an automotive environment. I designed it to handle the spikes seen in a noisy auto environment using an automotive grade switching dc/dc buck converter, with flybacks on all the relay controls and in a way that if the circuitry failed the relays would still be controlled from the temp sensor so the fans would still cool. the coolant after run was done using the newer low temp after run switch that triggered a relay. this is the new switch https://jhmotorsports.com/shop/catalog/after-run-aux-water-pump-switch-low-temp-with-ring-for-27t-p-639.html

if you need help with the arduino setup I'm very good with them. the first place i recommend stating is if your using the 12-20v in on the arduino barrel jack would be to get a good swithing supply as the regulator on board will burn out very quickly in a car with the swing in voltage and can see spikes over 20v.

the coolant fans should just be triggered by the stock s4 switch, one side comes on at a lower temp and the other at a higher, the low temp triggers the big fan and the high temp should trigger the smaller fan, both through a relay, then you can use you arduino, to trigger the same relay for the small aux fan. I would suggest a 5v coil 1amp relay with a flyback diode to trigger the 12v relay. the micro should have no part in the coolant fans as there is the potential for it to fail, such as frozen code(should implement a watchdog timer) or something not going just right, this way if it fails the fans will go on working and only rely on the switch and relay. as for the pressure sensor it is a 5v sensor with the signal rising based on pressure in the system and can be easily read using the ardunio analog inputs.

I have the arduino getting a signal from the temp sensor and sending out a pwm signal to my 4.2 fan module so if the arduino drops out the fans go on in a safe mode

As somebody who is still in the planning/parts gather stage of this swap, what is the benefit of going the custom fan controller route versus using the B5/C5 OEM unit? I snagged the stock controller out of the donor car. I'm curious what it's limitations are that are making so many go custom?

[blitz2190]

the ability to have it control the fan for the right on/off points for a/c from the b6 pressure sensor, to be honest you can run the oem unit and add a module that triggers the aux fan based off off the right voltage on the sensor, I'm just designing an all in one unit so I don't need multiple units, and In such a way that if a relay goes bad I don't have to scrap the whole unit just replace the relay or fuse.

Sent from my SM-N920V using Tapatalk

not a bad idea, I didn't bother with the need for PWM, mine is just an on/off setup, because of the expense if replacing those fan control units, which has worked well and reliably for a year, now I'm moving to the a/c control part.

[tankdeer]

So if I understand correctly it's basically it's to deal with the A/C part of the equation. To make it easier, and to provide flexibility in programming

[blitz2190]

correct, all last year I ran mine with nothing but the s4 switch and two relays, which is what your b5 oem unit would be doing. I just want to get everything working perfectly so I've been working on this a/c controller off and on since last summer in my spare time, which was none most of this year so now I'm back at it.

[replica_rs4]

Well, I guess it's my turn. I've got a 2.7T running in a B7 RS4. The tune is not complete, but I'm working on it.

I went with a BEL engine due to its CAN capabilities. The engine talks to the cluster without issues, and I presume I'll be able to port over functions from the AVK ME7.1.1 to the BEL ME7.1.1 so that both the fans and cruise control will work without issues.

I've documented everything on video so anyone looking to do this has some indication of all the changes that took place.

[blitz2190]

automatic? manual? if manual it should just be sure to use the spacer that goes with the 2.7, automatic again it would bolt together but then the problem becomes wiring the tcu, as the b6/b7 tcu is part of the engine harness, it's possible would require wiring the tcu into the 2.7 harness, just not something I'm aware of anyone trying as of yet. You will also need the 5.7 abs module with the harness plug make sure to leave a good size pigtail to wire. The wiring charts in my thread are known working in a b7 for the abs.

small side note, It seems I had recorded the voltage at which the a/c fan came on previously in this very thread. I'm fairly sure I have a working design, now just need to find the time to make the pcb and order the parts, the question is is there a willing guinea pig out there that wants to test it as my engine will be out for at least 3 more months. said guinea pig will get to keep the part if it works correctly, I will bench test the pcb for correct amperage(I designed for a 40 amp draw to be on the safe side) without genrating heat, and that the cooling fan side works before I send it, the test would be for a/c fan functionality.

Hello B6 swap guru's. Given the mostly straightforward description I have embarked on the swap. I have the engine all dressed and ready to go and it came with a harness attached (told it was auto). However I now suspect it was a manual harness as when I was taking the harness out of my B6 A4 3.0L automatic car I realized there is the separate connector for the Transmission Control Module that is not in the harness on my APB engine. Am I screwed? Could I rip out of my existing harness the TCM wiring and associated connectors? Am I better off buying a new harness all together?

Any and all constructive feedback welcome.

If you read through this thread you'll notice no one has done an auto swap that I know of yet, but it should be fairly easy from a wiring standpoint, the problem is your TCU for the b6 is part of the engine harness, and the TCU for the APB is in the body of the car so yes that very well could be an auto harness, which Transmission are you using, the one with the APB or from your b6

Everything else works. I get coolant temp readings via measuring blocks in VCDS. The cluster pins appear to be the same. Just wondering if it's a coding difference between the B6 and B7 clusters. You guys have had success with the B6 platform. I would think this would work, no?

you need the harness from the 2.7 engine wired to the b6 plugs, or if you don't want to cut up a harness AudiA4_20T makes jumpers if you can supply the female b5 connectors from the body and the b6 plugs from the harness.

[a2goblueguy]

can't imagine they are too far off, but I've said that before lol. if it helps they are both listed as 01V variants (01V4 in the b6, 01VZ in the b5)

Did you ever get this working. I am trying to do the same thing and have the B6 TCU harness integrated into the main wiring harness. My B5 wiring harness does not have the TCU wiring in it so I am wondering how you solved this problem. Did you simply open the loom and retain the stock B6 TCU wiring and connector and simply splice the CAN and KLINE wires into the ECU?

Thanks,

Bill

[a2goblueguy]

If you read through this thread you'll notice no one has done an auto swap that I know of yet, but it should be fairly easy from a wiring standpoint, the problem is your TCU for the b6 is part of the engine harness, and the TCU for the APB is in the body of the car so yes that very well could be an auto harness, which Transmission are you using, the one with the APB or from your b6


I am using the stock tiptronic transmission from my B6. Am I doing something foolish?

[blitz2190]

I'm willing to give it a go if you want to wire it. I can try and point you in the right direction but I make no guarantees that it will work.

Guarantees are not needed. At this point my choice is scrap the car and sell the parts or try this and hope with the collective wisdom around here we can make it work. Thanks for the help. Things will be a little slow during the holiday rush but I hope to get to this in the next couple weeks.

np, the first thing i recommend is, if you have not cut the harness, don't do so yet as it will make this much easier, what you are going to have to do is pull all the harness wrappings off from the all the transmission plugs all the way to the tcu/ecu box on the b6 harness, from there the 2.7 harness will be spliced in. Once you have that done you basically remove anything that doesn't connect to the tcu or wires to the transmission, If I'm right the only shared connections between the ECU and TCU should be the canbus wires the k-line wire,pin 37 on the ecu (I believe this is for cruise control), and power wires, when removing them I would suggest leaving good sized leads from the body plugs to make it easier to wire. you will need to re-use most of the relays in the ecu box most importantly j226 as this is the safety relay that prevents the car starting in anything but neutral or park.

Has anyone done B6 1.8t to 2.7t and used a 01A 5 Speed transmission? I need help and have questions about how you mounted your crankshaft position sensor. Did you have to modify the sensor to fit in the hole on the 01A transmission? Did you use the 2.7t sensor or the 1.8t sensor. My engine will only turn over but wont start. No rpms register on the tachometer when I'm trying to start it. Very desperate and need some help. Thanks.

[ADCS]

Don't know about the 01A, but for the 02X (1.8t 6speed) I used the crank sensor from a tiptronic 3.0 (same part number as the one on the 2.7t). Don't know if this applies to you but the crank sensor sometimes has a thin aluminum spacer under it. With the 02X this has to be removed allowing the sensor to sit slightly deeper into the bell housing. At first I didn't realize there was a spacer since it was stuck to the sensor. Did your sensor have a spacer and did you use it? Also, is your ECU coded correctly for manual trans? I believe the auto and 6spd have the crank sensor in different radial positions therefore it is critical that the ecu is coded correctly. I am not sure how the 01A and TIP compare.

Thanks for the reply! My car is originally a manual. I did notice that the sensor has an orange o-ring gasket and it looked like a black plastic ring which I thought was part of the sensor. You're saying remove both so that the sensor can sit flush? There is a spot on the 01A transmission for the sensor and that's where I placed it.

they seem to be in the same spot on the 01E and 01A so I don't see why it wouldn't work. have you tried looking in VCDS for a signal from the sensor? Is your ecu and A6 or S4? to work in the b6 it needs a S4 M-Box tune, there is one other tune that works (not sure but it's what apr uses as a base and worked on mine) to show rpm on the cluster as its done over can and the a6 tunes do not. flashing a factory m-box on the ecu is fairly easy as there is no immo to defeat.

Not sure what gasket you are referring to. Mine had an aluminium spacer the same shape as the base of the sensor about 0.100" thick. On the 02X the spacer is removed. I don't know about the 01A or 01E. You might need it still.

Has anybody upgraded their MAF housing and kept the 3.0 airbox?
Looking to get the 034 Motorsport 85mm MAF housing and was wondering if either of their airbox adapter pieces (S4/RS4) will attach to the B6 3.0 air box correctly? The stock hitachi MAF housing from a BEL attaches to the 3.0 air box fine so I am assuming the S4 adapter should work?

Housing:

[nefkntym]

I did sort of. I have 1.8T bottom and put the 4.2 lid on top. You have to cut up your existing MAF so you can bolt it to the box and still be able to clamp a hose to it. That will connect the box to the maf housing.

85mm MAF as well

I use an rs4 MAF with the 3.0 airbox, you need to get some plastic putty, fill in the area around the outside of the neck with a good amount then I used old guys trick with a cup wrapped with sandpaper on the inside once the putty has dried to widen it out to the correct size, and to get better airflow I used the aem dryflow filter. I used black putty and sanded it to look stock, this lets you use the factory clips for the MAF. I wish I was near my car to take a pic.

edit*

Best pic I can find at them moment if you look closely you'll see it clipped in with the metal clips, this was before I sanded the plastic putty on the neck.

[ADCS]

Awesome, thanks guys!

Aaron I like the idea of using the plastic MAF housing as an adapter. Nice. I have a couple spares I can hack up. Are you guys using the RS4 accordian tube up to the y-pipe? I only have the BEL and the 3.0 accordian tubes so I will probably just use a long 45deg silicon coupling.

[blitz2190]

I am, I used a section of 3" thin walled exhaust and a 3" id coupler to bridge the gap to the rs4 accordion hose

[Steve Bassen]

Easiest thing (IMHO) is just running the S4 upper box (lower is basically the same between all of them, aside from some sound deadening foam in the 1.8T) and the S4 V8 MAF (basically the same MAF as the B5 RS4). Just copy/paste the V8 transfer function into your tune and make sure you've got the Bosch offset in there, makes it all plug and play (unless you've got a later model B5 harness with Hitachi pigtail, anyways). It also supports an assload of flow without having to worry about scaling the housing and transfer function.

[ADCS]

Thanks for the input! I have a BEL with ME7.1.1 so it's more work switching to Bosch but that's a great option for the APB/ME7.1 folks.

My accordion hose is not from the rs4, I had one with the 770s but that went with the fueling kit for that. The one I have now is either the BEL hose or an APB hose. I had two laying around in the garage and I used the one that fit best.

[ADCS]

Thanks man. Look like BEL then. They are slightly longer than the APB.

[mobbin90]

would the 3.2 follow the same rules as the 3.0? also what about tranny bolting up (auto) ? I blew my 3.2 so i took this route and i am invested into it already and looking to manual swap it eventually.

[Carrture]

Can anyone tell me how to wire the b6 radiator fan using the b5 fan module? I've searched the posts and I can't make heads or tails on how this was done. Does theveryone b5 fan controller modules connect into the main harness? I don't think it does, but I'm not sure. Thanks for any help

It connects to the lower radiator hose switch and the fan, but on the b5 there is only one electric fan and that was the aux fan, the main fan was mechanical, the easiest method I've done was use 2 relays triggered by the same 2.7t lower radiator switch, there are 4 pins, which are just 2 separate switches, one set switches on at low temp and the other at high, I'll take a look at the diagrams when I get a chance to see witch is the low and high pins.

[Carrture]

Thanks for the reply. The lower rad switch is the blue sensor on the lower rad hose on the passage side? It's been stated that if you don't use the b5 module you will lose the function of the secondary water pump. Is this true?

My engine is in and it will start and run but then it starts to backfire at idle. Can't figure it out. Could it be my spark plugs if they are not gapped correctly? Here is my scan:

Clean your MAF, check connections on your cam shaft sensors. If the connections are fine for the sensors, replace them if you are still getting the same issue. If cleaning your MAF didn't solve the MAF code then purchase a new MAF.

So now that this thread is near ancient, what is everyone paying nowadays for a complete 2.7T motor? What engine code? Also, where did you buy your engine from? thinking i'll go to a pick and pull soon and snag whichever will be easiest and go from there.

ancient? I've picked up 2 complete engines the first was 500 the second for 300. the first was low mileage the second was 160k but I fully rebuilt the block and had machine work done. both from indy shops that listed them on craigslist and both apb, the second was a later BF apb block

Do you mean an ecu with the Infineon chip? As in a BEL with ME7.1.1? If so yes several people have used them. Arguably better then APB....

Hey I actually picked up the "kit" from Phillip down there at audis4parts as well. How'd you make out with everything he sent? I had to call up and get him to send me quite a few things that he missed or were broken but still I'm pretty pleased with the place so far. Motors pretty healthy and everything looks like it's gonna work out.....so far [emoji16]

Same here. Good customer service is fine if everything goes right. When they go wrong, that's when it counts. Phil has been great on sending missing, wrong, or broken parts. I still haven't got mine running perfect. It back fires at idle. Chasing down the camshafts sensor implausible issue. I had Phil do the timing, water pump, valve covers and cam seals. Hopefully nothing is wrong with the timing. If there is, I'm sure he will do what he can to resolve it.

do you have VCDS? its near essentials when doing a swap like this. If you plan on having a b7 or newer the full VCDS is a good thing to have, but if you plan on using it for just this and other b6's or older the $100 version is a great investment. I would recommend a real ftdi cable though not a Chinese knock off. this one works great http://www.ebay.com/itm/VAG-COM-VCDS-Cable-USB-Scanner-Tool-OBD-2-FTDI-KKL-409-1-VW-Audi-Ross-Tech-BMW-/291675299286?hash=item43e933ddd6:g:FboAAOSw1vlUyU7 M&item=291675299286&vxp=mtr

Anyone figured out the implausible crash signal code?
That's really the only thing left for me to deal with aside from wiring the cruise control and clutch pedal signal.

did you wire the violet/blue wire for the crash signal? is there any codes stored in the airbag module? I did need to clear some codes on my airbag module before and VCDS did not let me, ended up getting it with our modis computer. as far as I've seen, as long as everything is wired correctly there are no codes, I've done 3 swaps personally and all without codes, and there are 5-6 other cars running around wired like my thread that I'm not aware if they have any codes, at least not reported.

If I recall my '03 didn't have the wiring from the body plug to the ecu. I ran my own wire to the pin with no change. I've got to pull the engine soon so I'll go through and double check everything. I'll do the other wiring at the same time.

strange, the diagrams say it was discontinued starting in 2003, but my 2004 had it and wired in no problem. Possibly the chassis wiring still connects to here on the female body plugs and this is why it works, regardless the pin 69 on the airbag module is still the crash signal to all of the modules in the car, you can get to it at airbag module in the center console, or the ccm black plug pin 8.

Just did the engine swap, now i need the ECU and some wiring.

Does the APB engine use the same ECU as the AGB S4 engine? Or can i just use all ME7.1 ECU´s?

Also does any of you have a APB A6 wiring diagram? Im also in need of a A4 3.0 ASN wiring diagram, but think this is the wrong topix for that :)

Thanks :)

I'm not positive but I believe the agb is the euro version of the apb, difference in tunes and rear O2's and such but the ecu should be the same, just having a different tune. As to the wiring check my sig for swap wiring.

all data is a website where you can get a lot of diagrams for various makes and models of cars, they have the same diagrams found in the Bentley manual. They are great to have but I tried to lay out my charts in a way that they should not be needed as long as the person doing the wiring is fairly comfortable with wiring.

[jokh]

Thank you for the answers.

Also do any of you know if the trans space plate from the s4 is the same as for the 3.0 V6? or does any have the thickness of the s4 space plate between the engine and trans?

And i also have the impression that the AGB is the euro version of the APB, but still need someone to confirm if all parts and gaskets is a direct fit? My audi dealer wants a VIN number before ordering the parts so he is sure that they will fit.

yes you can use the 3.0 spacer, as for the AGB vs APB they should be the same as far as timing components, headgasket kits etc, and you should order from places like fcp, ecs, europaparts, and bluaparts, you can get oem brands for a 1/3 of what the dealer is going to charge you. example heres a headgasket kit (need 2) https://www.ecstuning.com/b-elring-parts/cylinder-head-gasket-set-priced-each/078198012e~elr/

[swamper8]

I have a question about the "Car-side" wiring of these kinds of swaps. I read through the OP list of needed parts and noticed that it doesn't say anything about dash harness, fuse block, body harness etc. Did Audi, in their finite wisdom, create some kind of standard across platforms/motors from "ECM box connections back into the car"? So basically you can plug in engine harness from a 1.8/2.7/4.2 motor into the same position / connectors within the ECM box? Reason I ask is because I have a 4.2L Allroad parts car. Motor is out. I was wondering if I had a 2.7T/ECM/harness, would it plug directly into the same ECM box connections as the 4.2L did? Or does the entire dash/body harness need to be swapped or connections re-pinned?
No I didn't read all 62 pages of this thread.
Thanks!

[blitz2190]

On almost every page there is mention of needing to rewire the harness including the first page but to answer yes ypu will need to rewire it for a b6 but on the engine hzrness side, my sig has the charts if you need them.

Sorry, just went and re-read the first page, missed this little blurb at the very end:

Wiring

- So everyone is freaking out about this wiring and it's not easy. Will I help you? Sure. Will I hold your hand and tell you where each wire goes? No. Maybe if this was 6 years ago and I had all the free time in the world, but I just plain don't have time anymore. I will be making plug and play harnesses based on chassis year, engine that came in that chassis, and year of the 2.7T. PM me for more information if you want to go that route.

I will check out your documents thanks!

Hello, guys, short question is the 5 speed auto from the A6 that comes with the 2.7t identical to the transmission on the Audi A4 3.0 or A6 3.0?

[teflon323]

has anyone done a 2.7t swap on a 1.8.t cabriolet b6 before? im in the uk also is it possible to do a quattro swap at the same time ?

[blitz2190]

Hello, guys, short question is the 5 speed auto from the A6 that comes with the 2.7t identical to the transmission on the Audi A4 3.0 or A6 3.0?

will it bolt to the engine? yes, but the axles will not swap over and most likely the propshaft will not as well. As far as auto goes you will need to wire the tcu as the b6 has it in the engine harness. I've looked over the wiring and it doesn't look to bad, but its just a theory at the moment as so far all have done manual swaps with the 2.7 as its easier.


has anyone done a 2.7t swap on a 1.8.t cabriolet b6 before? im in the uk also is it possible to do a quattro swap at the same time ?
I remember someone saying they had, it should be exactly the same, as for quattro, as long as you get the parts yeah, these cars are like legos, the part that doesn't bolt right in will be exhaust and wiring. I believe there is a fwd to quattro diy on here somewhere.

[Carrture]

Sorry for the late reply. I had to step away from my build to recharge. I do have the Ross-Tech VCDS. It would be though to do a swap without one.

[Spike00513]

Hello, guys, short question is the 5 speed auto from the A6 that comes with the 2.7t identical to the transmission on the Audi A4 3.0 or A6 3.0?

ZF 01V-type. Maybe the pdf spare parts catalog shows differences based on specific identification code, not just the general describing term '01V', since 01V was used in many cars, such as I think Porsche Boxster, BMW, C5 Audi, B5 Audi, etc. - sometimes people sell the transmission with the TCU it came with.
Maybe ratios vary, ie gear sizes and final drive.

Some are hall-effect speed sensors, others are induction.

you would need the matching cv axles, and matching rear diff if they are different, I don't know much about the GVE. If you plan on going bigger power later though I would look for a 01e.

No, as I haven't done it yet. It's a solid trans, that will easily handle your power goals. You will likely need to swap the axles with it, but everything else likely will be fine. It's been used by a few people before. Was going to use it ourselves but was able to source an 0A3 instead

Pull the whole drivetrain from the donor car. What transmission does your car have now?

It's got the average joe 5spd MT from 2003 with tired second gear's syncro
I always wanted to have a 6spd in this car since the day I got it (in 2008).

I'm just lurking around here toying with the idea of this swap as a fun project. Weighing all my options and shopping for parts. Still need to decide if I better start off with a different base than my current car B6 Quattro MT, but these days B6s sell for almost nothing so I won't get much for it anyway. So it's either drop a few grand and keep this old lady for long long time or get a B7 and start from there....or a dead S4 but in any way keeping the old seems to be most cost effective way to me

In your case I would do an 01E 6-speed swap from and early 3.0 B6 A4. You could do a GVE swap, but your brake light switch, crank position sensor, and wheel speed sensor will probably all need modification. A 3.0 01E drivetrain should able to drop right in for the most part.

[yuko3d]

Crank position? Brake light switch? Wheel speed sensor? Are we sure about all this, as in my general knowledge about cars all those components are NOT on the transmission.

[nefkntym]

Anyone want a almost finished running and driving swap car as a starting point or parts mule? I am ready to move on to other pastures.

[Ali SC3]

I am using the stock b7 2.0t manual transmission connected to the 2.7t but mine is in the b7 it came with so everything fits. driveshaft seems a little tight though but did fit.

[a2goblueguy]

np, the first thing i recommend is, if you have not cut the harness, don't do so yet as it will make this much easier, what you are going to have to do is pull all the harness wrappings off from the all the transmission plugs all the way to the tcu/ecu box on the b6 harness, from there the 2.7 harness will be spliced in. Once you have that done you basically remove anything that doesn't connect to the tcu or wires to the transmission, If I'm right the only shared connections between the ECU and TCU should be the canbus wires the k-line wire,pin 37 on the ecu (I believe this is for cruise control), and power wires, when removing them I would suggest leaving good sized leads from the body plugs to make it easier to wire. you will need to re-use most of the relays in the ecu box most importantly j226 as this is the safety relay that prevents the car starting in anything but neutral or park.

So I have finally had time to get back to this project and I am now more concerned that this may not be possible. What I am finding is that in my B6 wiring harness there are two wires that go directly from the ECU to the TCU (see attached) https://www.flickr.com/photos/147367897@N03/shares/6f1j50.

Now the issue. When pouring through the wiring diagrams in the 2002 B5 platform I do not find any such connection between the TCU and ECU. So my deduction is that in the 2002 B5 platform (the year of the 2.7T engine and wiring harness I am putting in the B6 platform) there was no communication between the transmission and the ECU.

So what I am coming to the conclusion of is that I cannot use a 2003 B6 Tiptronic transmission with a 2002 B5 2.7T Engine and Wiring Harness and Engine. Primarily because the ECU in 2002 needed to drive the 2.7T engine would appear to also need to know something about the transmission which it appears to not have.

Thoughts?

those wires are the canbus and its how the ecu communicates with the tcu and abs and other important drivetrain electronics, the b5 had this as well, in theory you would match the tcu with the transmission, wire the canbus and I think some others from the ecu(going from memory but I can look later) and flash the 2.7 ecu with an auto tune. The tcu for the b5 is in the chassis so it connected through the body plugs to the canbus.

The tcu for the b5 is in the chassis so it connected through the body plugs to the canbus.

So that was my hope as well... however when I look at the wiring diagram I attached, you'll see that the two wires I'm talking about come out of the ECU on pins 77/79 and then there are two wires coming out of the ECU on pins 58/60 labeled "high-bus" and "low-bus" but they seem to run to the instrument panel so I'm inclined to believe that you may indeed be correct regarding those two wires.

It would be awesome if I could find a pinout description of the TCU and ECU for both the 2002 and the 2003 model years. Any idea where I could find such a thing? The Bentley gives me the wiring digram but it doesn't tell me really what the pins function is.

My strategy from here is the following:
- Take all connectors and wiring from 2003 transmission and trace them out and pull them out of the existing 2003 wiring harness noting what pins and modules they terminate at if not in the 2003 TCU. If terminating in 2003 TCU, leave them there.
- Note the canbus wires from TCU to ECU ( need to figure out which is high and which is Low)
- Remove the 2003 wiring harness from B6 platform
- Install 2002 2.7 Wiring harness
- Install 2002 ECU and flash auto tune
- connect TCU canbus wires to high/low canbus somewhere convienient
- Install clint's jumper harness 'cause there is only so much mess I want to deal with

Sound about right?

there should be a third wire as well that I believe is gn/bl on 37 related to cruise control. but yeah those two wires are the can between the ecu and the tcu, you should be able to tap the drivetrain can signal to the tcm from the b6, the b5 ecu did it over the drivetrain canbus instead of a separate one like the b6, but as long as the data messages are addressed to the same module it should be fine, which i would bet they are.

It should work with any 5.7 unit, I don't know if the lines are the same though, for an easy install your going to want the brake lines that connect the master cylinder to the abs unit, its doable without them(some bending required) but plug and play with them. Also remember you will need the yaw rate sensor from behind the radio head unit.

I believe it may with a bel ecu, some have reported that it has worked but never said apb vs bel, my reason for thinking it will with a bel is I believe the ecu communicates with abs over can as apposed to the apb which only works over k-line and thats not present on the 8.0. Now the downside is there is a whole lot less tuning options for the bel.

when you pull it out make sure not to cut the pressure sensor wires, and be sure to mount the yaw rate sensor in the same orientation.

I too have heard a lot of speculation that theoretically with a BEL you could potentially retain some of these features, as well as the tuning limitations. But again, it's just speculation from what I've heard. I would love to keep the 8.0, as well as the B7 cluster, but who knows.

you may be able to keep the b7 cluster but not sure yet, Ali SC3 is going to try swapping the b7 ccm for the b6 and see if that fixes it, from what I was able to find the ccm tells the cluster about the warning. That signal doesn't exist in the b6 so a module swap may fix it.

That would be rad. One less thing to screw with. Plus that extra 10mph speedo, ha ha.

I am curious what else would change with a B6 CCM though

Untrue. The good tuners all offer tunes for the BEL including stage 3. You just may not be able to find a run of the mill Nefmoto tuner.

I'm attempting to use the 1.8T radiator support but know the 1.8t radiator won't work. So I bought a 3.0 radiator thinking that it would fit, which is didn't since the 3.0 radiator is 18" tall whereas the 1.8 is about 16.5" tall.

The lower portion of the core support, where the 1.8 radiator sits, gets in the way when trying to use the 3.0 radiator.

So, I decided to modify the core support to accept the 3.0 radiator. The lower metal support is still structurally sound and will be more than capable of holding the snub mount.

thats exactly what I did and it worked fine. Can't wait to see this thing together.

[Bob Marley]

Hoping someone can clarify... which Transmission Spacer to use?

01E103551A

*or*

01E103551C

I've seen info supporting both numbers...
FYI*
I have a 2001 APB A6 Manual going into a 2005 3.0L 6speed Ultrasport

I'm leaning towards the 551A Spacer but not sure if there's a difference I should be aware of, or are they the same?

Thanks guys

"A" was superseded by "C", I would go with which ever one you can get cheaper.

[MoparFreak69]

I'm attempting to use the 1.8T radiator support but know the 1.8t radiator won't work. So I bought a 3.0 radiator thinking that it would fit, which is didn't since the 3.0 radiator is 18" tall whereas the 1.8 is about 16.5" tall.

The lower portion of the core support, where the 1.8 radiator sits, gets in the way when trying to use the 3.0 radiator.

So, I decided to modify the core support to accept the 3.0 radiator. The lower metal support is still structurally sound and will be more than capable of holding the snub mount.


That tube isn't structural at all. It is just the boost crossover tune. You won't run into any issues like that as long as none of the cut edges can damage the radiator.

The cut edges were sanded down with a sanding disc to ensure there are no sharp edges.

So they are the same...551A & 551C

Thanks that's what I thought...

For the radiators, you can use a 30V radiator from a B5 Passat. They are 16.5" like the 1.8T but they have the inlet/outlet just like the 2.7 and 2.8 engines.

Same width too?

You can, I did too, but they don't fit well at all. I picked up a 3.0 radiator to replace mine just because I don't like how it fits.

Steel.

thanks, good to know

Anyone did the swap from a 3.0, and have the wiring diagram from the 3.0 engine?
Or can you assume that audi used the same wiring colors in both the harness?

[b7_Andy]

Everyone here has swapped from a 3.0, this is why this thread is over 60 pages. It's filled with all that kind of info.

did actually read all the pages, lots of great info. But not 1 single wiring diagram is oploaded for that engine? So the question is only in case someone reading this thread had the diagram and would share it. :)

This couldn't be any further from the truth. The OP swapped from an S4, which is 4.2, and a lot of others swapped from 1.8, including myself, and 3.0.

The information is out there. Just gotta search

It was a joke, by that I meant a lot of the swaps are 3.0 swaps. And Blitz has wiring diagrams and spent a lot of time making charts to understand exactly where certain wires go.

Have been using it, but only counts for the 1.8t. does not match up with the 3.0

matches up just fine, I've used my chart on all of the b6 chassis(two 1.8's, one 3.0, and one 4.2 that I've swapped personally, one of the 1.8t started as an auto as well and swapped to a 6 speed at the same time). The differences are fixed using the the additional wiring relays to supply power. With the help of a few others on here testing, everything posted in my thread works. Just be sure to read pass the chart as there is a reason for the additional wiring section

Thank you very much, will do the wiring tomorrow and hopfully it will start:)

Hi all.

So i just read thru all the 63 pages of this thread and cant find an answer. Or missed it.

Im buying complete car 2001 A6 2.7t and want to swap the engine to my a4 b6 1.8t BEX fwd. I have 6 speed manual. Can i fit the 2.7t right on it(with the plate?)? My gearbox code is HES.
Thats the last thing keeping me from the swap atm so i would appriciate some info so i can go ahead.

Thanks

[tankdeer]

Yes it will bolt up to your FWD trans just fine

[Nowich]

Thank you.

[jokh]

I am looking for anyone that could confirm if the swap should work with stock 3.0 harness and ECU (ME7.1.1) if you remap the ECU to control the boost.

Anyone knowing or did this them self?

not without a good amount of work and the only one I know of to add boost control to an n/a ecu was biche on his vr6 swap. Not sure which version of me7 he was using though. As for the harness not without a huge amount of re-wiring if you thinking of using it on the 2.7. Theres no reason to do this unless you where trying to use the 3.0 heads on the 2.7 which I don't think anyone has actually seen through yet that I know of.

[Bob Marley]

I posted a similarly question a while back regarding the Trans Spacer part# needed for the swap... 01E 103 551A or 01E 103 551C ...I was told that one part# just replaces the other. However I have a 2005 3.0 Ultrasport with an 01E 6speed tranny already...I believe my part# is the same... so I guess my question is simple as I'm trying to source all parts BEFORE I start wrenching... Do I need a 2.7t Trans Spacer for the swap or can I use what I already have?

I'd hate to get held up on a part mid project. Anyone know for sure?


Thanks

This may be a crazy question to ask, but which rear differential will be best to install once the swap is done. Currently my B6 has the stock unit that came with the car(B6 3.0 Quattro) and I wondered if I could benefit from using an S4 unit from a B7 or something similar. I have tried the search and google, but nothing concrete has come up. the 'Bay has a few "RS4" units for a whole lot less than the JHM LSD complete diffs.

Don't get me wrong the car is pulling like a freight train, but have a locked rear just sounds more fun, specially in the warmer days.

use the one that matches the correct gearing of your transmission, haven't heard of any diff's going out before transmissions, but the jhm lsd conversion isn't a bad price compared to all the others, after I'm through with my new engine this and the 4:1 were my next goals.

That's what I'm looking at as well. Currently just getting everything ironed out and the SS 304 exhaust finalized

Ok Good to know...

If don't mind me asking...which cooling fan Option did you decide on...Did you leave the 2.7t Mechanical Fan setup in place & find a way to trigger that? Or did you wire a trigger for the OEM B6 Electric Fan setup...Need to know the easiest option to get up & running...adjustments can always be made later on.

I used two relays triggered by the 2.7t lower fan switch. took me all of 15 minutes. the mechanical fan doesn't fit, the b6 one triggers both fans while it works its just more taxing on the electrical system then it needs to be, the best option if you don't want to wire in your own relays would be the b6 s4 modules because there are two of them, but then they are just oversized relays at that point.

Ok...so say I wasn't too concerned with the 2 fans spinning ...just use the OEM B6 Fan control module...triggered by the Lower Fan switch...

Any idea where I could peek at the schematic for both? As in which wire from the Lower Fan switch to use as trigger to which wire onB6 Chassis Fan Module.

Finally I'm guessing by removing the mech. Fan I'd need that kit by JHM to block off the opening

I just too the fan off the clutch so that I could keep the factory belt length, basically it becomes an Idler pulley. my wiring thread in my sig has the 2.7t fan switch pinout. the one going to the bigger fan is the lower temp on which is where you want to use if not doing both fans separate.

Ok...I'll check that out

...and as for the b6 fan module? Which wire to tap for trigger? Or is that in your Wiring write up as well...don't mind hunting for the answer if I'm being a pest.

I will be using Clint's Plug/Play Harness btw...but I don't believe provision is made for the various fan options.

the jumper harness has nothing to do with fans as the 2.7 ecu doesn't know about them, you would cut the smaller wire at pin 2 on the 4 pin plug to the fan control module, then run that to one side of the temp switch then the other side back to where you cut it going to the fan control module, so it should be pin 2 red/grey wire -> temp switch -> red/grey wire going to FC module. Just an fyi for if your testing, once power is applied to this wire it takes a few seconds for the fans to come on as its waiting for a signal from the ecu, then once it doesn't get it, it will turn both fans on at full speed.

Ok...got it. So I'm basically just inserting the leads from 2.7t lower switch in series into the Red/grey lead on Pin #2 going to Fan Module (4 pin Harness). When Temp is reached switch closes...Both Fans are Tiggered...
