Parking sensors on RS6 (V8) broken - how to reset? or fix?

[Namor]

Just had the car serviced and parking sensors have gone faulty for no apparent reason. They beep repeatedly when engaged (without an object being near) then stop. Green light just flashes at you. Parking sensors don't work at all.

any ideas on how to reset them or get them working??

much appreciated.

Thats the parking system telling you its dead. Im affraid it'll be a trip to a VAG garage (unless you have VAGCOM) to check which sensors have failed (if not all) and then a trip to Audi to order some up. Its quite common on the RS6 now and im affraid its no cheap fix. You can refit them yourself if you know what you are doing but getting some of them out is really difficult so best leave it to the experts if you are unsure. You'll be needing them painted too. Bloody technology eh!! RS246.com has some info on there as some of the users have had the same issue.

Ignition on
Car in Reverse
lightly touch each sensor

you will just feel each one pulse

The one that ain't punsing is the dead one.

In my experience VAGCOM can't always tell you which sensor it is! I had the "computer says no" argument with Audi who insisted my sensors were fine! Oncve they tried driving the car they realised but it took them 2 attempts to replace the correct sendor

Or listen to them, assuming you have a quiet enough place to do so and good enough hearing. Did that and traced the failed one on our A8, which the VAGboxthingie then confirmed. Unfortunately, having replaced that, it's still buggered.... control box apparently.... $$$$ to fix surprise surprise.

great many thanks for your tips, I'll try tracking down an accommodating VAG dealer asap. just feels odd as sensors were working fine and it's not as though any were damaged in an impact. I guess its just the vagaries of electronics. frustrating stuff.
