Direct TPMS Installation Guide

[VeryBadman]

There has been ongoing discussion about direct TPMS retrofit but I don't think anyone here has ever summarized the steps or instructions to do it so I decided to take this matter into my own hands. After lengthy research for required parts, installation process, and codings, I have pulled the trigger to execute the installation and successfully retrofitted direct TPMS system into my car.

Here are a couple of pictures to demonstrate that the system is really working on my TTRS.

And here are the parts you will need to retrofit the system:

1. TPMS Antenna (P/N: 8S0907273)
2. RDKS Tire Pressure Wiring Harness
3. 4 TPMS Sensors of 433 MHz frequency (P/N: 5Q0907275B)
4. Antenna Holder Bracket (P/N: 4E0810675B) - This is optional

Or you can cut all hassle from chasing after all parts and get the TPMS kit from this seller on eBay:
https://www.ebay.com/itm/202335867045

I also recommend you to get a mini fuse tap adapter and 10A fuse to tap power wire to fuse panel but you can improvise your own method as long as it works.

Once you have the parts ready in hand, follow the following steps to retrofit the kit!

1. Take off the lateral TT cover from the driver side and remove the first bolt (marked in red circle in the picture) on the side behind the cover that holds the big cover under steering wheel, the fuse panel is behind that cover making it a fuse panel cover and a big one at that.

2. Remove the second bolt above the gas pedal.

3. Remove the last bolt next to OBD2 port, now all 3 bolts are off and you can remove the fuse panel cover.
https://i.imgur.com/LmMs5Ujl.jpg


4. In the process of remove the fuse panel cover, there are 3 connectors that are plugged to light switches, LED foot light, and wireless key antenna, make sure that you unplug them before taking the cover off. Please check the pictures below for better understanding.

https://i.imgur.com/XE6eSR8l.jpg
https://i.imgur.com/tNgJ4phl.jpg


5. With the fuse panel cover out of the way, remove the top plastic trim cover next to where the lateral TT cover was.
http://i.imgur.com/RK6srUel.jpg
https://i.imgur.com/mgFgw7Ml.jpg


6. Move on the remove the plastic trim cover next to the door sill, this piece is held tight so you may need a bit of force to remove it.
http://i.imgur.com/wLpqHl7l.jpg
https://i.imgur.com/1obFdvUl.jpg


7. The 2 plastic trim covers hold the trim cover between them in place, with those removed you now can remove that piece but you will need to remove hood release lever first.


8. To remove the lever, there is a lock behind the joint and you need to release that first to be able to pull the level out. Please check the pictures below so you get the idea how they come together and how to take them out.
https://i.imgur.com/sGuIDfgl.jpg
https://i.imgur.com/8ehbNyql.jpg
https://i.imgur.com/iKNUoSHl.jpg


9. Once the lever is off, pull the plastic trim cover out to expose the CAN bus.
https://i.imgur.com/I1S3cHpl.jpg
https://i.imgur.com/86DTdrpl.jpg


10. Now that the covers are removed and we have access to both CAN bus and fuse panel, let move on to work in the trunk. You have to remove cover to expose the tools tray and remove the tray as well.


11. Install the TPMS antenna in the trunk next to battery and run the wires, we need orange/grey wire, orange/brown wire, and red wire to CAN bus and fuse panel in the front and we need to tap the brown wire to body panel for grounding. I picked to secure the brown ground wire with bolt in the middle as you can see in the picture.
https://i.imgur.com/k1v76Ail.jpg


12. You can secure the TPMS antenna however you want but I simply use 3M industrial grade double side tape to do so.
https://i.imgur.com/cEmKtzZl.jpg


13. Back to the front, look for black connector which is extended CAN connector. We will tap orange/grey wire from antenna to grey wire in black connector and tap orange/brown wire from antenna to the wire of same color in black connector. Please check pictures so you know what I'm talking about and don't mess up.
https://i.imgur.com/yY8Ep0Ul.jpg
https://i.imgur.com/kdM4EGNl.jpg


14. Move on to tap the power to fuse panel, look for 6th fuse from the left which is 10A fuse and take it off.
https://i.imgur.com/uHrV5eCl.jpg


15. Connect red wire to fuse tap adapter, insert 10A fuses to the adapter, and insert the adapter back to where we removed the fuse in the step earlier.
https://i.imgur.com/Cxm6GeZl.jpg
https://i.imgur.com/eBMaCfrl.jpg


Now the parts installation part is done, put everything back in place. There is also a trick to put fuse panel cover back that you better tighten the bolt above gas pedal back first or else you will never be able to tighten it.

I will explain for the coding part in the first comment.

[VeryBadman]

Now we move on to coding part to make this work:

1. Enter 03-ABS Module, you need to do this first thing to disable passive TPMS system.
https://i.imgur.com/HtU1lIjl.jpg


2. Enter Coding - 07 menu, select Long Coding Helper.


3. Open Byte 12, make sure that Bit 7 and 6 are Inactive.
https://i.imgur.com/jHYBXJHl.jpg


4. Open Byte 23, make sure that Bit 0 and 1 are Inactive.
https://i.imgur.com/9GaxePCl.jpg


5. Exit and Save the change.


6. Enter 19-CAN Gateway, you need to enable CAN bus to recognize the direct TPMS system.
https://i.imgur.com/iGEF175l.jpg


7. Enter Installation List menu, look for 65 - Tire Pressure, select and Save Coding
https://i.imgur.com/aN13au4l.jpg
https://i.imgur.com/p5Hc2Nql.jpg


8. Enter 17-Instruments, you need to tell CAN to not look for passive TPMS signal and look for direct TPMS signals instead.
https://i.imgur.com/NrmF4qRl.jpg


9. Enter Coding - 07 menu, select Long Coding Helper.


10. Open Byte 3, make sure that Bit 7 is Active.
https://i.imgur.com/zpQ47cbl.jpg


11. Open Byte 4, make sure that Bit 0 is Inactive.
https://i.imgur.com/SUXxKmgl.jpg


12. Open Byte 11, make sure that Bit 2 is Active.
https://i.imgur.com/M7RbvFkl.jpg


13. Exit and Save the change.


14. Enter 5F-Information Electr, you need to enable Direct TPMS menu in the Virtual Cockpit from here.
https://i.imgur.com/RRbHFDal.jpg


15. Enter Adaption - 10 menu.


16. Look for Car_Function_List_BAP_Gen2-tire_pressure_system_0x07, make sure that it's activated.
https://i.imgur.com/QkfCu7pl.jpg


17. Look for Car_Function_List_BAP_Gen2-tire_pressure_system_0x07_msg_bus, make sure that Databus extended is selected.
https://i.imgur.com/VdErLN9l.jpg


18. Look for Car_Function_Adaptations_Gen2-menu_display_rdk, make sure that it's activated.
https://i.imgur.com/09c97DDl.jpg


19. Look for Car_Function_Adaptations_Gen2-menu_display_rdk_standstill, make sure that it's not activated. This option is for making TPMS functions under Service menu accessible when the car is moving.
https://i.imgur.com/PhByXF3l.jpg


20. Look for Car_Function_Adaptations_Gen2-menu_display_rdk_over_threshold_high, make sure that it's activated.
https://i.imgur.com/L71kQzUl.jpg


21. The coding is done, reset the MMI and clear the error codes that might happen in the process. In the case you don't know how to reset, you have to push the 2 buttons forward and press the MMI touch know at the same time.
https://www.audiworld.com/forums/attachments/tt-mk3-discussion-207/94673d1528570822-how-reset-tt-rs-mmi-photo418.jpg


22. After MMI is restarted and the error codes are cleared, you should be able to see TPMS menu in the sport display and in the Service and Maintenance menu.


23. The last step is contacting the tire shop of your choice to have the TPMS sensors installed in all 4 wheels.



That's it! Now the direct TPMS system retrofit is done. One thing you should know and don't freak out is that the pressures and temperatures won't show up right away, you only need to drive a bit for the information from sensors to show up on your virtual cockpit screen. If the car complains about TPMS malfunction, make sure that you tap the CAN bus signal wires to extended CAN bus, power wire to fuse panel, and ground wire to car body frame properly.

Let me know if you have any questions!

Wow excellent write up, thanks a lot for this! In canada for 2018 direct tpms was not available but now I can tackle this project!

[David@EuroCode]

Awesome work, thanks for sharing with the community!

[Cyttorak]

You are indeed a VeryBadman...holy smokes what a write up. Super impressed.

This is great. How did you figure it out? Also, what are you using for software/hardware for VCDS? I may be wiling to take a shot at this as I already have the sensors installed in my new wheels.

I was told that antenna mounted under the rear bumper cover but looks like this work, so close enough.

Great job, Thanks for posting.

Great job, Thanks for posting.

There were discussions on Audi UK forum that I read countless times to understand what I may need to do and when I placed order with that eBay seller, I also asked him back and forth for installation instructions and codings. With 2 sources of information combined, I have come up with the plan for what need to be done exactly and while I was proceeding with installation, I took photos and documented for every steps I was doing.

For the coding part, you only need Ross-Tech VCDS cable and nothing else. Some other tools that provide similar functionalities to VCDS should work also but I'm not going to bet my money on that.

And yes, you are right about the antenna is supposed to be in the bumper near to rear right wheel to make the system working properly but I figured that placing the antenna in the trunk next to battery should work as well and it really works and that made the installation much simpler.

[McTTRS]

The eBay link has disappeared (sold out?). Do you have the parts number for the RDKS SET Wire?

I don't have part number for RDKS wiring harness but it seems to be a generic harness shared across multiple models and brands under VAG. Anyway, I have updated the link so it will go to the post that is live.

Or you can follow that link in this comment.

I sent the eBay seller a note to see if he would just sell the antenna with the wiring harness, without the wheel sensors as I already have them. I can't find the wiring harness separately. I'm sure with cars that come equipped with this option, the wiring is embedded in the harness already. This seller is just making it easier to add stand alone I would think.

[ormandj]

Wow, I've been looking for this information for a while. Excellent write-up and great work figuring it out.

[RightonRed]

Just ordered. Gonna give this a try with an '18 RS3. Thanks for the writeup and link!

[Cyttorak]

I ordered as well. Thanks!

[VeryBadman]

I have updated coding instructions to make TPMS functions under Service menu accessible when the car is moving. It's in step 19.

Any reason the think the antenna NEEDS to be in the rear of the car, I know oem is in the bumper and you put it in the trunk but is there any reason to think the antenna wouldn't pick up the signal if it was placed say under the steering column area just to simplify install even more? Let me know your thoughts.

Actually that’s a very good question. The reason why antenna has to be in the trunk is that the computer identifies the wheel placements by the distance from each wheel. If you put the antenna under steering column, the readings will be off and the numbers on the screen will not represent the right placements.

Thanks VBM, you are a Ninja with this stuff :) I ordered the cable.
Could you also have hooked up power to a fused lead attached near the battery, or maybe that would always be hot?

I haven’t checked about it but if it’s 10A, I think it should be fine.

I believe it can be done but there has not been a proven example yet. On TT UK forum a bunch of TT and TTS owners tried this retrofit and reported back that they are suffering TPMS screen coming on and off intermittently and no one confirmed that the issue has been resolved.

Truthfully speaking, I was unsure that mine wouldn’t have the same issue when I started the project but it turned out to be perfect.

[ormandj]

I've ordered all the parts. Quick question: I see you tapped two wires into the extended can bus connector. Is there any trick to doing this? I haven't taken mine apart so maybe it is obvious. Did you use any special connectors or somehow otherwise connect these wires to the connector?

No, I only trimmed the ends of the 2 wires, inserted into the slot, and used flathead screw driver to push into place.

You can also splice and tap into the wires if you like.

[Cyttorak]

I’m not savvy enough to try this by myself. My dealership is currently doing this installation. Fortunately they treat me good on side projects. Hopefully, I’ll be able to report a second successful retrofit this afternoon

Now that’s a great dealer relationship. I wonder if they will also put that antenna in the rear hatch area by the battery?

Keep us updated, I now have the parts, but am not really familiar with coding and don’t have the interface yet.

I took it in and unfortunately they couldn’t get to it. The tech who does theses sort of special projects was working on something that’s taking longer than anticipated. So taking it back in Monday. He did review the instructions and seemed confident it would be a slam dunk. But he did say he was going to bring in his vag com to do the programming. He didn’t think their diagnosis equivalent, started with an O, was going to let him do the programming.

While there though, it was brought up that there is a device called obdeleven. A Bluetooth ob2 transmitter and app system, only for android devices, which has a bunch of preprogrammed “long coded” tricks. Which as a layman I take is what all the coding verybadman figured out but this device/app system does it for you with a press of a button. So you can turn off the seatbelt chime, open door chimes, brake light intensity, have side mirrors tilt when in reverse, memory heated seats, tail light stuff and on and on. It also allows you to do long coding. So if you don’t have a vag com you could buy this dongle, supposedly $60, but its $97 on Amazon.

So somebody could add all this coding as an app and all the end user would have to do it turn the TPMS on is open the TPMS app and turn it on.

I don’t have an android device but the videos I’ve watched on YouTube say you can download the app for free and check what all preprogrammed tricks are available for your platform. All I can find is the TT/TTS/TTRS does have apps available.

Can anybody with an android device confirm? Probably for another thread. But certainly interested in seeing what kind of customization we could do.

Hopefully I’ll be able to update on Monday my TPMS is working

I can confirm that that I am now the proud owner of the worlds 2nd? TTRS retrofitted with the VC TPMS! Service manager just called me and said it’s ready to pick up. I’ll post pictures later tonight.

Also, they routed the wire differently. SM will explain when I get there.

HUGE shoutout to Verybadman for figuring this out!!

Since no one else confirmed that he has successfully retrofitted the system, I think it’s safe to say that you are the second.

For the wiring I believe dealership would do it differently from mine. The key is that the antenna should be placed in the right rear side of the car in which the actual position should be in the right side of bumper so I think they must have done it that way and route the wire to the CAN bus. It doesn’t matter how they wired it as long as it works.

I’m glad that my installation guide can be helpful.

They removed the side panels in the trunk and ran the wires behind them to the battery location for the sensor.

More work but same result. This car should come standard with this feature.

You have to pop off the rear plastic panel. Ran into the same thing, and it's a bit tough to pull off.

Thanks for doing all the leg work on this, I ordered the kit and a couple extra sets of sensors for other wheels, had the sensors installed on my current winter wheel set up and going to do the wiring install this wkend… there is some other VCDS stuff I want to try so it's a good time to do it all.
Cheers!

Does anyone happen to know what the behaviour will be if I install this upgrade on my '18 TTRS (CDN), but then run winter wheels without the required sensors?
i.e., Will the system default back to "regular" low-tire pressure monitoring using wheel speed sensors, or will it start throwing errors, or... ?

Thanks!

It will throw low tire pressure/no signal found error. I would suggest you to install the sensors in your winter set as well.

This is awesome, amazing job.

Hi VBM,

I'm finally getting around to doing this (and a few other things) while my car is hibernating for a few months here in Wisconsin. Your write up has been fantastic help. I've noticed though that the wire coloring is slightly different on mine than yours. I have Orange/Brown and Orange/Green instead of the Orange/Grey that you have. I'm just trying to confirm that the Orange/Green is the same as your Grey as I don't want to mess this up.

Here is a picture, would you be able to take a look at yours to help me confirm this?

Thanks,

[naber]

Rapture,

The antenna connector has 4 pins, pls see the image attached.

Pin 1 from the antenna connector goes to B109 connection, Can Extended Low. It is 6th pin in black T17 connector, brown/orange wire.
Pin 3 from the antenna connector goes to B108 connection, Can Extended High. It is 5th pin in black T17 connector, grey or orange/grey wire.

Both connectors are numbered, so you shouldn't have any issues)

[Rapture]

Thanks Naber. I will take a good look at this prior to making the connection. It looks as though the picture I took is the reverse of the picture of the antenna connector in the electrical diagram.

Thanks Again naber.

I went back and double checked this, I'm not so good at reading the electrical diagram but I am very good at following instructions. I checked my Antenna connector and pin 1 on mine is an Orange/Green wire and Pin 3 is Orange/Brown, it could be grey but it's not light gray and seems to match the color of the wire in the 6th pin of the T17 connector. What's is bugging me about this is, step 13 in VBM's write up:

"13. Back to the front, look for black connector which is extended CAN connector. We will tap orange/grey wire from antenna to grey wire in black connector and tap orange/brown wire from antenna to the wire of same color in black connector. Please check pictures so you know what I'm talking about and don't mess up."

If I did what is suggested above and matched what I think is the Orange/Brown wire to the Orange/Brown wire in the T17 connector that would be the reverse of the pin instructions you provided. My Orange/Brown wire would be attaching to the Grey wire in the 5th pin of T17, and my Orange/Green wire would be attaching to the Orange/Brown wire in the 6th pin of T17.

I realize the wiring harness I bought could be different or maybe the wires are just not installed in the correct pin but it's messing with my head a bit. If your instructions are correct in terms of pin to pin connections then I would caution people to not follow the color coding in VBM's write up and follow the pin to pin instructions if they do this retrofit.

Just to say it, I appreciate all of your help on this, I just don't want to make a mistake and mess something up.

please let me know what you think.

[Dr Bill]

After reading this, paying for the Dynamic Package makes a lot more sense!

My luck, I'd have a pile of parts left over after taking the car half apart! LOL

[Cale262]

Thanks for doing all the research!

I have everything installed and working but I am getting the wrong readings for the TP, I've inflated my tires to 36PSI front and 32PSI rear but the reading I get is 32PSI right front, 36psi left front, 36PSI left rear and 32psi right rear. I've tried relearn a few times now over the last week but it still reads the same. I've gone over all the VAGCOM coding and it's all correct and checked the tire pressures and they are correct... any idea of what I should try next?

TIA

[naber]

Rapture,

Here's the screenshot from ELSA. It gives the same wiring instructions. It's better to rely on wiring diagram and pin-to-pin connections rather than wire colors.

Cale262,

Where's the antenna located? It should be in the left rear corner, in trunk or underneath the bumper. It should also be stricktly perpendicular to the car's body, otherwise the RDKS system will be unable to identify the front/rear wheels correctly. Try playing with the antenna location, it's definetely not the coding issue.

[Dr Bill]

Thanks for doing all the research!

I have everything installed and working but I am getting the wrong readings for the TP, I've inflated my tires to 36PSI front and 32PSI rear but the reading I get is 32PSI right front, 36psi left front, 36PSI left rear and 32psi right rear. I've tried relearn a few times now over the last week but it still reads the same. I've gone over all the VAGCOM coding and it's all correct and checked the tire pressures and they are correct... any idea of what I should try next?

TIA

Try rotating the antenna 90 degrees. Looks like it thinks the front tires are on the left side of the car.

[Rapture]

Rapture,

Here's the screenshot from ELSA. It gives the same wiring instructions. It's better to rely on wiring diagram and pin-to-pin connections rather than wire colors.

Cale262,

Where's the antenna located? It should be in the left rear corner, in trunk or underneath the bumper. It should also be stricktly perpendicular to the car's body, otherwise the RDKS system will be unable to identify the front/rear wheels correctly. Try playing with the antenna location, it's definetely not the coding issue.

Thanks naber,

I finally found that section in the manual this weekend, evidently I was spelling "tyre" wrong when I searched. I agree on the wiring diagram, it was simply boiling my brain. I asked VBM if he could send me a picture of his connector just to put my OCD mind at peace :)

We've always thought that antenna was on the right side of the car, a picture is worth 1000 words.

I had the harness and antenna installed professionally, I gave them the link and asked them to follow the OP instructions. Looks like they didn’t catch that in the included photo and the antennas is installed 90* in the wrong direction as you commented. I’ll rotate 90* and test again but I’m guessing that will correct the issue.

Cheers!

In theory the installation should be the same but you will need different antenna and wiring diagram.

[n0v4]

Hi, i tried to find any information about it. Than as far as i know the rs6 does have it. But i cannot find any information about parts and connections diagrams.

I don’t think so but the worst thing can happen is that you will get to see TPMS screen flashing on and off.

I should add that I procrastinated about rotating the antenna but after a 2hr drive the system corrected itself... smart system [:D]

The system had the correct orientation for a short time and then went back, I rotated the ant and all is good.

New issue, I installed the eBay kit tpms sensors in my winter wheels and all was good. Just swapped over to the summers and the shop installed some generic sensors that also shared 433.92mhz but I keep getting a low tire warning lamp...it is reading the correct temp and PSI but always the low tire error even after setting the pressure in the MMI. I am guessing its the generic sensors. I went to my Audi dealer and they wanted over $200/each for the Audi TPMS sensors. Does anyone have a link where I can get some TPMS sensors for a better price, I have two more sets of wheels I need these installed on and I think the dealers price is absurd...maybe I have to bite the bullet but thought I would ask here first.

TIA for any help, Cheers!

I bought extra set off eBay and they work perfectly fine. However, make sure that the part number matches with the one I mentioned above or otherwise it won’t work. VW group make 2 TPMS sensors of 433 MHz with different part numbers but they aren’t interchangeable.

I totally failed to see that on the very first post of this thread. I ended up biting the bullet and purchasing some from my dealership as I wanted to get my summer wheels sorted out ASAP. I also ordered two more sets via ebay for my for track wheels. The eBay units were a quarter of the price (same part number), dealership $100/each and a set of four from eBay were $100 shipped. Dealership shocking sticker price shouldn’t be a surprise to me as a new grill fo my TT RS (modified mine for a radar install) is $1800.

*above prices in Canadian dollars

Having an issue with saving tire pressures. I'm running 275/30R20. Ive set the fronts to 33PSI and the rears to 27PSI (Cold). When I drive the car it keeps telling me I'm loosing pressure in the rears. once the tires warm up they are @ 29+ PSI and the system accepts this pressure without issue... Is 27psi too low for the system, has anyone else had this issue?

[Rapture]

I finally received my steering wheel back after having some stitching work done to it and some other interior items (I'll post a separate thread on that after I have all of the parts back and installed) and was able to complete the install of the TPMS system. Unfortunately it is not working for me. I've double checked the new hardware and software installation and believe I have everything installed correctly. I do see the new display in the VC but it does not update any pressure or temperature.

I have a "Tire Pressure Monitor" error message. I've tried driving the car for a bit hoping it just needed to reset itself but no luck.

I'm now wondering if I have the correct transmitters mounted in the wheels. I had them installed when I originally purchased the wheels hoping that someone would figure this retrofit out, and I've assumed they are the correct ones as I provided a VIN for an RS that had this option installed when I ordered the wheels.

I did a VCDS scan and received the error below. I don't completely understand the message, but it makes me feel like the receiver is working properly and trying to read the sensors in the wheels.

Can anyone help diagnose this?

Thanks Larsmate,

I also posted this on the Ross-Tech forum and received what I think is a similar response. They said there that if the antenna module is new (not used) it has never been coded with information and won't work until it is. Used antenna modules, even if the coding isn't for our specific car would work as at least it has a basic setting. Is that in line with what you are saying?

I did make a bit of progress yesterday, I moved the Antenna from being taped inside the foam tray in the hatch to under it and now the VCDS Scan does show the wheel sensors which I'm happy about and at least know they are communicating. I thought I was home free, but I still have the TPMS Malfunction.

Sounds like I either need to find a mod-friendly dealer or learn Vag Can Pro. At least this riddle may be getting closer to being solved.

Again, I appreciate your input,

Yes you'll need VCP or dealer help. From my experience, at least in my neck of the woods, dealers are reluctant to help with mods while the car is under warranty. Best bet is to find someone on the forum with VCP nearby.

[Rapture]

I went to the dealer today and I think basically my part is defective. He said he could not load any parameters on it, and even called the Audi tech "hotline" to see if they had an override code to help, but that did not work. He pulled a similar but newer part off a 19 RS5 and everything worked fine. I guess that at least solves the mystery, and that I did install it correctly. $300 later and I have to find another part. At least I know the root cause now. I think I will purchase the newer part number just because. The Tech also said he has never had to "code" one of these parts as part of the installation process.

Awesome, Ive had all kinds of issues with mine especially when swapping wheels. Did you happen to get the new part number?

[Rapture]

Funny, I just responded to your other post. I have not received the replacement part yet but they will be sending the same model number. If it does not work correctly I will probably get the newer part number. There is a newer software loaded on it, not sure if that makes much difference but who knows. I sure would like this to work.

[Rapture]

I think I've pretty much confirmed that if you try this install with a brand new, not used antenna module you can not get this to work. I had another antenna delivered (thanks Norbert) and I have the same results as before. VCDS shows the same error on the antenna module. New antenna's need to have some parameters loaded on them for the system to function. I am obtaining another antenna from a seller on eBay that will load the parameters for the TT RS on prior to shipping. My local dealer was unable to load the parameters after trying for a few hours. VCDS cannot load the parameters as stated in a previous reply, this requires Vag Can Pro, or a dealer that is proficient at updating the module.

I'm going to put the 2 antenna's up for sale in the classified's if anyone is interested, they are both new but will require someone that knows how to upload the parameters on them to function properly.

I'll provide an update after receiving the 3rd (hopefully fully parametrized) antenna.

Is the implication that following the DIY will no longer result in a working config because new antenna in the supply chain have incompatible software?

[Rapture]

No, I am just trying to share information that I have learned as part of the retrofit.

Brand new antenna's from Audi, that have not have been used in a car need to have "parameters" loaded on them for the specific vehicle. They do not have this software on them when delivered. If they are put into a vehicle that originally had the option the Audi dealer software installs the software to make the part work for the vehicle. If you install the part in a car that did not originally have the option the Audi dealer software won't install software because it knows the car didn't have the option based on the VIN. Some dealers may know how to "fool" their software or use a 3rd party software (Vag Can Pro can, VCDS cannot update this software) to install the required software, my dealer could not.

There doesn't seem to be many people in the U.S. that use or are familiar with the Vag Can Pro software, I could not find anyone to help load software on the antenna's I have.

Some vendors that supply an upgrade kit know this and they will preinstall the software required for the antenna's to work properly, others do not. Full disclosure, interestingly and a bit confusingly another member here bought the parts from the same place I did and theirs is working, can't quite explain that.

I've tried 2 new antenna, they didn't work, VCDS recognized them but they showed a fault coded indicating "invalid data set" and "missing calibration / basic setting". No software loaded.

Used antenna's will work, even if they are not for our specific vehicles because they have software loaded, the dealer pulled one from a 2019 RS5, plugged it into my car and everything worked even though it was a different part number.

I ordered from another vendor, asked for the parameters to be loaded for a 2018 TT RS, and they said no problem, will do. That part should be here late next week and will hopefully make this work for me.

[big residual]

Thanks for that Rapture. Would be interested in finding a vendor who can sell antennas with working software loaded too.

[Rapture]

Thanks for that Rapture. Would be interested in finding a vendor who can sell antennas with working software loaded too.

Here is the eBay seller I ordered the antenna from. They seemed very knowledgeable about coding these with specific parameters for the vehicle. https://www.ebay.com/itm/Neu-Original-Audi-VW-8S0907273-RDK-Reifendruck-Kontrolle-TPMS-HW-4M0907273B/283226133750?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 If you do purchase from them, be sure to communicate that you would like the antenna parameterized for your specific vehicle.

I'm also a big fan of the seller I purchased the antenna from originally, they are very good and I've ordered several other items from them. They just were not familiar with the coding requirements for this.

I'll report back when I have the new coded antenna to (hopefully) confirm it worked.

[big residual]

Who was your original vendor?

[Rapture]

Who was your original vendor?

The folks here https://www.ebay.com/usr/audi.rs.performance?ul_noapp=true. I have dealt with Norbert directly on a number of items and they are great to work with, excellent service and pricing. I purchased the OLED's from them (as have some others here).

[Rapture]

I received the new antenna today with the "parameters" for the vehicle pre-loaded. I plugged it in, and had no TPMS malfunction beep or fault indicator. I took it for a drive and after about 10 minutes, it began to receive a reading, finally this retrofit worked. Woo Hoo!! Learned a lot on this one.

Now, I just have one last thing to figure out. The pressure readings on my VC display is showing in KPA versus PSI. Interestingly the temperature is in Fahrenheit not Celsius.

Anyone happen to have a clue on how I may change this? Looks lie a job for VCDS, just need to determine where, what.

Thanks for everyone's help with this, now I actually have all the options I originally wanted.

[Rapture]

I was able to change the VC display from kPa to PSI based on instructions I received from the Ross-Tech forum. All is good.

[big residual]

Can you test connections on this without the sensors being mounted in actual tires?

[Rapture]

Can you test connections on this without the sensors being mounted in actual tires?

The sensors need to be activated. I’ve learned along the way here that some sensors are activated by the pressure they are under when the tire is inflated so this maybe a yes or no depending on if they are brand new and not activated yet.

How long would I need to drive until sensors are calibrated?

Few days ago I way puting a winter tires and I saw that I have direct TPMS. Since I recently got my Passat B8 I'm not sure if previous owner just bought tires with direct TPMS or he also installed antenna and wiring inside the car.
Is there an easy way to check if direct TPMS is istalled?

[kevin#34]

can you see tires pressure/temp data on VC?

[nemili]

No since in VCDS indirect TPMS was enabled.
When I enabled direct TPMS under TPMS it was showing "Loading data..." and I drove for 5 min but I got no data.

[kevin#34]

coding problem?

[nemili]

I was able to add/tutn on everything. Only thing is when 65 - Tire pressure module is enabled I'm not able to access it.

I'm guessing if there is no comunication with module in VCDS then the actual antenna is not installed.

[kevin#34]

if so, you should check for the antenna presence (or not)…
as staded previously by Naber , "It should be in the left rear corner, in trunk or underneath the bumper"

[kevin#34]

I'd like to retrofit the active TPMS at next tire change, are there any evidences it can work on TTS too?
I see that veryBadman installed the antenna on the right side of the trunk near the battery, while the factory-fitted one is on the left side near the bumper, it means both positions work?

Hey guys,
I picked up the kit from Eurozone (https://eurozonetuning.com/products/audi-a3-ttrs-rdks-direct-tire-pressure-monitor-system-retrofit-kit). The wire colors aren't matching what I have, but the adapter they provided seems like a better setup. I assume I'm supposed to de-pin the car's connector and put those pins into the Eurozone connector, then run the pigtail to the OEM harness. However, I don't know what colors go where. I have Orange/Brown, Orange/Gray, and Gray. Also unclear has to how to tap the fuse holder for power (assuming my Gray wire?) given what I have. Looking for guidance.

Hi Solution,

Go back and read posts 42-50 on this thread. I struggled with this as the wire colors on the adapter I bought also did not match the OP's. You need to rely on the wiring diagram to ensure you connect the proper wire to the connector under the door sill. You wont need that extra connector that is on your harness, you can strip the wire and shove them in the connector, then tape it and it should work fine (you can of course use the pin method if you are handy with that).

I also learned the hard way that the antenna needs to have coding on it for this to work, and I had a difficult time finding anyone in the U.S. that knew how to code the antenna, and had to buy one from someone in the UK that did know. I have 2 new spare antenna's if anyone is interested.

Hi Kevin,

I removed the Styrofoam structure in the trunk and used Velcro to mount the antenna under the plastic trim surround at the back drive side corner of the trunk in the same orientation as the factory mount. It's probably about a foot away from the factory mount location. I thought about mounting it in the factory location, but it did not seem worth the additional work. I removed the lower cushion of the rear seat and routed the wiring along the left side, under the plastic trim in the hatch area, and then under the seat. With the seat removed, I used a hangar to fish the wires under the plastic side panels by the rear seats to the door sill area which leads to the wiring harness you need to attach the wires to.

[kevin#34]

many thanks.
do you think that in my case, the compact spare wheel presence will prevent to install the antenna unit in the same position as you?

No, you should still be able to route the wires. It will just be easier if you pull the spare tire out.

The Antenna is positioned in a small open area to the left of where the styrofoam structure is. You’ll see the spot when you remove the foam.

There has been ongoing discussion about direct TPMS retrofit but I don't think anyone here has ever summarized the steps or instructions to do it so I decided to take this matter into my own hands. After lengthy research for required parts, installation process, and codings, I have pulled the trigger to execute the installation and successfully retrofitted direct TPMS system into my car.

Here are a couple of pictures to demonstrate that the system is really working on my TTRS.

And here are the parts you will need to retrofit the system:

1. TPMS Antenna (P/N: 8S0907273)
2. RDKS Tire Pressure Wiring Harness
3. 4 TPMS Sensors of 433 MHz frequency (P/N: 5Q0907275B)
4. Antenna Holder Bracket (P/N: 4E0810675B) - This is optional

Or you can cut all hassle from chasing after all parts and get the TPMS kit from this seller on eBay:

I also recommend you to get a mini fuse tap adapter and 10A fuse to tap power wire to fuse panel but you can improvise your own method as long as it works.

Once you have the parts ready in hand, follow the following steps to retrofit the kit!

1. Take off the lateral TT cover from the driver side and remove the first bolt (marked in red circle in the picture) on the side behind the cover that holds the big cover under steering wheel, the fuse panel is behind that cover making it a fuse panel cover and a big one at that.

2. Remove the second bolt above the gas pedal.

3. Remove the last bolt next to OBD2 port, now all 3 bolts are off and you can remove the fuse panel cover.

4. In the process of remove the fuse panel cover, there are 3 connectors that are plugged to light switches, LED foot light, and wireless key antenna, make sure that you unplug them before taking the cover off. Please check the pictures below for better understanding.

5. With the fuse panel cover out of the way, remove the top plastic trim cover next to where the lateral TT cover was.

6. Move on the remove the plastic trim cover next to the door sill, this piece is held tight so you may need a bit of force to remove it.

7. The 2 plastic trim covers hold the trim cover between them in place, with those removed you now can remove that piece but you will need to remove hood release lever first.


8. To remove the lever, there is a lock behind the joint and you need to release that first to be able to pull the level out. Please check the pictures below so you get the idea how they come together and how to take them out.

9. Once the lever is off, pull the plastic trim cover out to expose the CAN bus.
https://i.imgur.com/I1S3cHpl.jpg
https://i.imgur.com/86DTdrpl.jpg


10. Now that the covers are removed and we have access to both CAN bus and fuse panel, let move on to work in the trunk. You have to remove cover to expose the tools tray and remove the tray as well.


11. Install the TPMS antenna in the trunk next to battery and run the wires, we need orange/grey wire, orange/brown wire, and red wire to CAN bus and fuse panel in the front and we need to tap the brown wire to body panel for grounding. I picked to secure the brown ground wire with bolt in the middle as you can see in the picture.
https://i.imgur.com/k1v76Ail.jpg


12. You can secure the TPMS antenna however you want but I simply use 3M industrial grade double side tape to do so.
https://i.imgur.com/cEmKtzZl.jpg


13. Back to the front, look for black connector which is extended CAN connector. We will tap orange/grey wire from antenna to grey wire in black connector and tap orange/brown wire from antenna to the wire of same color in black connector. Please check pictures so you know what I'm talking about and don't mess up.

14. Move on to tap the power to fuse panel, look for 6th fuse from the left which is 10A fuse and take it off.
https://i.imgur.com/uHrV5eCl.jpg


15. Connect red wire to fuse tap adapter, insert 10A fuses to the adapter, and insert the adapter back to where we removed the fuse in the step earlier.

Now the parts installation part is done, put everything back in place. There is also a trick to put fuse panel cover back that you better tighten the bolt above gas pedal back first or else you will never be able to tighten it.

I will explain for the coding part in the first comment.


Now we move on to coding part to make this work:

1. Enter 03-ABS Module, you need to do this first thing to disable passive TPMS system.
https://i.imgur.com/HtU1lIjl.jpg


2. Enter Coding - 07 menu, select Long Coding Helper.


3. Open Byte 12, make sure that Bit 7 and 6 are Inactive.
https://i.imgur.com/jHYBXJHl.jpg


4. Open Byte 23, make sure that Bit 0 and 1 are Inactive.
https://i.imgur.com/9GaxePCl.jpg


5. Exit and Save the change.


6. Enter 19-CAN Gateway, you need to enable CAN bus to recognize the direct TPMS system.
https://i.imgur.com/iGEF175l.jpg


7. Enter Installation List menu, look for 65 - Tire Pressure, select and Save Coding
https://i.imgur.com/aN13au4l.jpg
https://i.imgur.com/p5Hc2Nql.jpg


8. Enter 17-Instruments, you need to tell CAN to not look for passive TPMS signal and look for direct TPMS signals instead.
https://i.imgur.com/NrmF4qRl.jpg


9. Enter Coding - 07 menu, select Long Coding Helper.


10. Open Byte 3, make sure that Bit 7 is Active.
https://i.imgur.com/zpQ47cbl.jpg


11. Open Byte 4, make sure that Bit 0 is Inactive.
https://i.imgur.com/SUXxKmgl.jpg


12. Open Byte 11, make sure that Bit 2 is Active.
https://i.imgur.com/M7RbvFkl.jpg


13. Exit and Save the change.


14. Enter 5F-Information Electr, you need to enable Direct TPMS menu in the Virtual Cockpit from here.
https://i.imgur.com/RRbHFDal.jpg


15. Enter Adaption - 10 menu.


16. Look for Car_Function_List_BAP_Gen2-tire_pressure_system_0x07, make sure that it's activated.
https://i.imgur.com/QkfCu7pl.jpg


17. Look for Car_Function_List_BAP_Gen2-tire_pressure_system_0x07_msg_bus, make sure that Databus extended is selected.
https://i.imgur.com/VdErLN9l.jpg


18. Look for Car_Function_Adaptations_Gen2-menu_display_rdk, make sure that it's activated.
https://i.imgur.com/09c97DDl.jpg


19. Look for Car_Function_Adaptations_Gen2-menu_display_rdk_standstill, make sure that it's not activated. This option is for making TPMS functions under Service menu accessible when the car is moving.
https://i.imgur.com/PhByXF3l.jpg


20. Look for Car_Function_Adaptations_Gen2-menu_display_rdk_over_threshold_high, make sure that it's activated.
https://i.imgur.com/L71kQzUl.jpg


21. The coding is done, reset the MMI and clear the error codes that might happen in the process. In the case you don't know how to reset, you have to push the 2 buttons forward and press the MMI touch know at the same time.
https://www.audiworld.com/forums/attachments/tt-mk3-discussion-207/94673d1528570822-how-reset-tt-rs-mmi-photo418.jpg


22. After MMI is restarted and the error codes are cleared, you should be able to see TPMS menu in the sport display and in the Service and Maintenance menu.


23. The last step is contacting the tire shop of your choice to have the TPMS sensors installed in all 4 wheels.



That's it! Now the direct TPMS system retrofit is done. One thing you should know and don't freak out is that the pressures and temperatures won't show up right away, you only need to drive a bit for the information from sensors to show up on your virtual cockpit screen. If the car complains about TPMS malfunction, make sure that you tap the CAN bus signal wires to extended CAN bus, power wire to fuse panel, and ground wire to car body frame properly.

Let me know if you have any questions!
Just came across this thread, hats off to Badman for writeup. [emoji1319][emoji1319][emoji1319]

To me coding part is easy as it is pretty straight forward but wiring part isn't.

Some cars have locked ABS modules and cannot be coded. I circumvented the security in the ABS module for my 2019 SQ5 (80A907379K) which would not take any coding at all. To do this, I used ODIS-E V14.1 and flashed it to the lastest version of firmware. The module rebooted in a non coded state (the whole coding string was zeros). In tis state I was able to write the full coding string and it accepted it. I did this recoding with both ODIS-E and VCDS.

This means that you can compute the coding string in VCDS, copy it into a notepad document, zap the ABS module, reboot it and code it to that string. After that you need to zap all trouble codes, restart the car, and use VCDS to set the basic settings (reset all adaptations, un the parking brake all the way out and in routines), reset all DTC's and boom, powercycle the cand you are good to go.

The new coding is now locked and you will have to go through the whole loop again to change anything, but that's better than not being able to at all...

I installed a kit from AliExpress (it's in Canadian dollars). Followed the all the installation instructions in the thread -- thank you.

On my cable...

orange on cable to orange/brown on canbus
orange/green on cable to grey on canbus

The red +12V was not long enough to make it from the fuse box to the trunk but I spliced in some spare ground wire to make it work. The sensors were recognized in about 30 seconds.
