The Official B6 2.7T DIY/Swap Guide

[Evil27t]

That's why I'm so confused. In the owners manual for the B7, it shows a light that says MIN. Mine says max. I'm wondering if I should have used the V8 sensor instead of the 2.7.
Does anyone else have a swapped B7 S4???

mines say max as well ...... im sure its just the sensor and how it reads is all. That gas cap warning im all lost on for now.

[grigor88]

I think the reason you have this warning is because s4 only had minimum oil level warning so running the s4 sensor and harness does not max oil level so your cluster is looking for that second signal from the sensor, what you might have to do is find that wire in the ecu box coming from the body harness and probably ground it

The problem is that both sensors only have 3 wires... Also, I went on ECS and sensors seem to be interchangeable between Allroad and B7 S4. Thats pretty much my setup. I cant just ground the wire. Cluster looks for a voltage reference.

[Mr. Wolfsberg]

Install a resistor?

If they are interchangeable and like you said the cluster looks for a voltage reference, this maybe too obvious and you might already tried it, but I would either try the sensor out of 4.2 or order one for s4. Did you check part numbers on ecs if they are the same?

Yes thats what I am saying. The part number for a C5 Allroad, which is the setup I have, is the same for B7 S4 and vise versa.

If I had my original sensor, I would use it. They other problem could be the shape of the oil pan and the way the sensor mounts in the pan. Maybe I have the right sensor, but it thinks the oil is too full.

i have same isue for max oil level if you find out the problem let's me knows

any way to bypass the sensor ? with vag com can we delete the option of max oil level sensor ?

Kristof...

ABS still working good? The 5.7? No warning lamps?

I can't imagine the B6 and B7 S4s being any different. I have not had any issues with oil level warnings on my B6. Using the B5 sensors with wiring matched to the car. Where are you getting your wiring info from?

I have the right wiring info. If you read other members' posts, they are experiencing the same issue I am. B7s has a max oil as well as the min oil. The problem we are having is with the max warning.

[imallstressed]

Did anybody other than Kristof do the 8.0 to 5.7 ABS swap??? I started mine today, but I realized there is no VSS wire coming from pin 33 of the 5.7 module I got for the swap. I was wondering if others had experienced this. I can easily install a terminal there, but I am confused why it is missing.

Huh. Didn't know the B7 had that. In that case if the cluster (the CANbus gateway) is expecting to see a signal you either need to send it a signal (use B7 sensor) or change the cluster to a B6 unit ?

Does anyody know if a B6 cluster will work in a B7? This may also eliminate my loose fuel cap warning problem.

Has anyone successfully installed an AUTO 2.7T into Manual 6-Speed car yet ? I'm having difficulty locating Manual Trans engines for a good price, but I'm locating complete Automatic cars for around $1300.00
- Yes I researched and I didn't locate a successful swap
- I did however learn (or was led to learn that the cranks on both AT and MT cars are identical)
- I also read that a Pilot bearing was needed
- Then I read that the Pilot bearing was not needed and is actually built into the flywheel

[Mr. Wolfsberg]

I bought a whole 2.7 car with an auto but have done the swap yet, there is most certainly always a pilot bearing in a flywheel but as to if it built into the flywheel idk as this is my first 2.7 but if it is it would be the first one I've ever seen

Not to derail the questions being asked, but update.

Got the engine in to it's cradle.

To do list:
Fuel Return line
Figure out ac lines
Extend downpipes
Stare at current flow charts for many hours and cut and splice dozens of wires

[nefkntym]

The cranks are the same. But the auto cranks sometimes have a plug in the end of the crank. The pilot bearing does go in the flywheel, but there is a small stepped extension at the end of the input shaft that goes past the pilot bearing. Just put some heat on the back of the crank and give the crank a whack with a rubber mallet to get the plug to come out.

my motor came from an 01 allroad which was auto. posed no issue mating up with the 6-speed.

Is there a member on here who makes harnesses for people? If so, who that may be? Feel free to PM me if your that member.

[Boost_creep]

His name is Clint, and he's the OP.

Did you take any special steps to bolt it up ?

[Ali]

Just a B5 S4 trans spacer plate.

the 2.7T auto crank and manual crank is the same part Sam. The auto uses a spacer on the crank that the flex plate is bolted to. The manual flywheel is pressed onto the crank where the auto spacer is. Its great in that you don't have to touch the engine.

engine crank sensor trigger is on the trans bellhousing triggering off the ring on the flywheel.

Pilot bearing is in the flywheel. another gem I like over the 1.8T stuff. I hated having to remove the pilot bearing from the 1.8T crank. removing and installing it on a flywheel is so much easier.

I can send you some pics tonight. My first engine was from an S4 MT and my latest engine that I'm currently using is from an A6 AT. My trans is a 6spd from a B6 S4. I'm using the 01E trans adapter/spacer plate and cobbled bellhousing bolts together out of my box of bolts.

[dougyfresh]

Sam. If you want my S4 2.7T I'll sell it to you really cheap. It needs a bore w/ new pistons and a valve job on the heads (broken valve). Perfect candidate for a solid high HP build.

I flashed my car with an MBOX file, and no dice. I don't believe I have the right MAF, but how does the MAF interact with the tach?

When I scan my car with VCDS, live data shows the correct RPM.

I am stumped, any ideas?

[Boost_creep]

I'm sorry guys, I know this has probably been covered. But which power steering line will I need, and will an allroad line fit ok?

What's your actual problem?

It should. Any B5/C5 line

[Boost_creep]

It should. Any B5/C5 line

Thanks so much for your quick response. But which line? There is more than one. Is it the feed line or the return?

[AudiA4_20T]

Just the feed line that goes from the rack to the rear center of the engine.

[Boost_creep]

Thanks so much!

Have you guys heard Ard design? How's their 3'' down pipe, compare with ebay 3'' down pipe?
Here is their link

And, does anyone have a economy choice for the downpipe? looking for something is affordable for now...
Thx

Modified piggies will be cheapest. ARD used to make stuff but it looks like they're not in business anymore... $375 is dirt cheap but make sure that you'll actually get the product

Is that meanining this ard design is kinda fraud?? what about the silly rabbit motor?
I was thinking about getting one from ebay... But I found the silly rabbit.... They seems better than the ard

SRM downpipes = SSAC

[Poopcorn]

SRM downpipes = SSAC

Okay.... any ideas which is better tho? the ssac? or ard 3''?
I know they are all aftermarket parts.... and the prices are pretty close...
And btw, what about the x-power downpipe? Are they all same?
Thx

[Steve Bassen]

XS Power = SSAC, as well. They're fine, just don't expect the stainless to stay stainless for too long. I'm blasting and coating mine with Cerakote to keep them from getting surface rust...

what about putting the heat wrap on?

[Steve Bassen]

Cheap stainless shouldn't be wrapped, IMHO... risk of making a corrosion issue worse since it traps moisture in, when the car's not running.
