    Hi guys, need help.

    Noticed that the rear parking sensors aren't working. The odd beep, sometimes silence. Walked around it when in reverse and nothing, not a chirp.

    Also noticed the reversing light isn't working? (Heated seats seem to be on the same fuse, and they're ok) so sure it's not the fuse.

    Wouldn't the computer/dis pick if the bulb has gone?

    I think it might be a switch somewhere, any suggestions.

    Thanks

    P.S. car is 3 dr 07 tdi quattro

    Would of thought there would be a switch on the gearbox so when you select reverse it activates the lights and sensors... could be that?? :ermm:

    get the car scanned for a fault. OEM sensors run off canbus and have their own controllers. unless of course you have those £20 sensors in the car.

    Sensors are factory fitted, OEM so no £20 halfords specials.
    Don't know anyone with vagcom, only audi dealer = fleecing!

    Just wondered if anyone had came across this before.

    Anyone know if a reversing bulb would be picked up by the computer/dis?

    reversing bulb should be as far as i know, again this can be check as a fault code on VCDS and you can also check the coding on the CE to see if the cold diagnostics is enabled for these bulbs.

    I'm in Kilwinning :)

    If its the switch the DIS might not pic it up as as far as its concerned its just not being used but a scan might reveal something. I too reckon its the reverse switch, dont know where its located on the gearbox though LOL.

    oh, I've got VCDS - meant to say that LOL

    Thanks mate, that makes sense. If the dis doesn't know the light is being switched on, it can't tell there is a fault. That would explain it. I was quite surprised to see no reverse light and nothing in the dis

    Need to find the switch now!

    You the guy with a sister working in the Brisbane in Largs? might need to catch up for a cuppa!
