Massive shout out to Simon Ryder for his original post. I got the servo fault after returning to Heathrow with the car (A4 Avant MY17) sat there for 5 days. Drove home carefully and found this thread. Down to local Audi centre today, picked up the last pressure sensor they had in stock and fitted it on the drive in 5 minutes. If I can do it, anyone can do it. All error messages gone. Does feel like a massive win considering it would cost £200 for a garage to do it or worse, £3000 if you don’t deal with it fast enough.
I have to say though, I think it is pretty p*ss poor from Audi that they haven’t issued a recall for this. This is clearly a major problem affecting many cars which could result in huge cost to the individual, especially since the car itself actually encourages you to keep driving! A real cynic might say……. Anyway, I will be sending some correspondence to them saying as much. Not good enough.
