I had my front tyres changed and as part of that I made them change one of the TPMS sensors that previously seemed like it was playing up, but only during motorway driving.
After the tyres were changed, the car gave a Flat Tyre warning. I hit Save Pressures, as normal and the error disappeared. But then there is absolutely no TPMS display, even though the error was gone. Things stayed this way even after multiple drives.
I needed me to clear all the faults using VCDS, for the TPMS display to start working again.

Perhaps to reset the TPMS and initiate a look for a set of new sensors id's and values it needed a hard reset.

Well Bruce, that’s concerning. I just swapped my winter tires for the summer set with their own set of sensors.First drive, warning appeared “wheel change detected” with TPMS warning. Stopped, restored tire pressure values, All good.

I’ve read this thread start to finish now, and just wanted to say a big THANKS to the contributors. 👍🏻
I’ve ordered the AliExpress kit and will be installing on my 2020 RS4 (yes, the UK spec ones don’t have this as standard any more, not even an option when I spec’d up the car.)
The only bit i can add to this thread will be a 3D printed holder for securing the receiver module inside the car, on the right hand side. STL file to follow…
I’m sure cable ties work well, but I like a clean looking install 😁

I think it’s nuts to retrofit something that just increases cost and complexity. One of Audi’s best deals was the ABS-Linked TPMS without those spendy wheel-mounted pressure sensors.

Agreed. I cannot thank VAG enough for not seeing the TPMS light on the dash all winter while I run my snow tires...

And regarding "spendy sensors", they're $35 per wheel.

The pros and cons of direct vs indirect methods are well known, we all have our preference. This thread is about direct TPMS retrofit so I think it's nuts to drop in a thread and start answering questions that haven't been asked.
