Thanks to all for this thread, very informative. The warning came up on my 2019 Q5 when driving home yesterday. I rang Audi assist this morning and they came out to my house and replaced the sensor within an hour. Impressed to say the least. If you have Audi assist, highly recommend calling them to get the sensor replaced.

Here’s a a few pics…..
