Hi all,

So glad I discovered this forum.

6 weeks ago, while reversing my 2016 A6 S line, my dashboard started to light like a Christmas tree, showing the following errors/faults:

- stabilisation control (ESC/ABS): fault!, see owners manual

- hold assist: unavailable

- main beam assist: system fault

- tire pressure: system fault!

- parking brake!

- Audi adaptive light: system fault!

- brake servo restricted. You can continue driving. Please contact workshop.

 

Since then, I probably did a further 500 miles and the car drives as normal...or at least I didn't feel anything suspicious with it; lights work ok, it brakes ok, steering wheel is ok, parking brake holds ok. 

 

Have any of you experienced similar? Do you have any advice?

Thank you.

 

I second, DO NOT DRIVE ANOTHER MILE! 
Yes, buy the sensor that’s listed in this thread and change it before you drive it again. I didn’t, and it cost me a fortune to replace & repair the subsequent damage.

It's the brake booster pressure sensor

Thank you both for the valuable advice. Just ordered one from Amazon; will share my feedback after I fit it.

Good move Sorin.

i had the same message, drove 19 miles all the while the message only stated “ contact garage”. But my car totally failed. It cost me nearly £4k. I hadn’t found this forum 😩  Don’t move another inch until you have fitted the new part.  I now carry a spare in the car in case it goes again.

Bought new sensor from audi and tried to replace it myself. I was able to release the wiring clip but not able to release the clips at either side. Any advice?
