I have a 2004 B6 A4 with front and rear sensors.
Last week the two right hand front sensors stopped working and the system
makes random high pitched beeps as if it's a loose connection.
I doubt the sensors themselves have gone but wondered if anyone had come
across a particularly week connection for those sensors that causes them to
It may be a coincidence but the right hand headlight washer failed to
retract completely the day before the sensors failed but has been fine
since. I put that down to the washer reservoir being almost empty so the
headlight washer couldn't pressurise completely and thus only raised the
washer about half an inch.
I've read a few cases of two front sensors going out at the same time and
people being quoted £300+ to get them fixed by Audi as they don't come
painted. I'd be grateful if anyone who has had this happen can let me know
I may just buy the sensors and get a bodyshop to do the work as I have a few
bits that need painting so it's probably more worthwhile to get them fixed
if a batch of paint has to be mixed. Might also get a couple of extra
sensors as spares in case this happens again.
