Hello

Problem:

Factory fitted rear parking sensors have stopped working.

Current situation:

Almost every time: get one long loud beep (then nothing else) when engaging reverse gear.

Occasionally (now very infrequently): get "normal" quiet short beep followed by exactly 9 "bips" then the long loud beep (nothing else), when engaging reverse gear.

Tried so far:

Read various forum posts here and other VAG sites. Got a tip that the most likely thing was that just one of the 4 sensors had packed up rather than the control unit. Did the suggested tests and indeed it seemed that this was the case. So, bought a new sensor and replaced the "faulty" one. No difference! On the off chance that it was still just one sensor, I swapped the new sensor into each position in turn. No joy.

Question:

Anyone got experience of this? Is it likely that there could be more than one sensor faulty? Is it more likely to be the control unit? Is this something that would produce a definitive diagnostic fault code?

Any help / advice appreciated.

Thanks.

Stick it on VagCom, it should give you a fault code(s)
