    Hey guys, I've realised that when I put the car in reverse, it makes a beep but they dont really work. Sometimes they may make one set of beeps followed by a beeeeeeep. But they dont start intermittently beeping as I get close just when I get too close it suddenly goes beeep. The front ones work fine. I heard it could be one dodgy sensor causing them all to not work properly. How can I diagnose this? Does anyone know what could be wrong with them or what to check for?

    By the way I do not have a VAGCOM nor can I afford one atm.

    I had the same issue with mine,turns out to be the mid rear sensor, fixed under warranty but still had to pay for it to be colour coded.can't remember what the total cost was but it was along the line of " how much".they are great when they work but heard they do fail from time to time.but I'm sure you will need to plug your car into some system to tell which sensor is out.
    maybe you could post your area,somebody could point you in the right direction....

    Good luck,

    I've got the same problem, occasionally it work ok and beeps as it should, but recently more often than not when putting the car into reverse it just beeps constantly, that is until I get close to something and then it beeps as you would expect.

    My guess would be you (or we) need to find someone in your local area capable of diagnosing fault via VAG, few of the guys on here have them I think, to find out which sensor is faulty. However, replacing the sensor and getting it painted & fitted etc won't be a cheap job. If you find an easy/cheap way around this please keep us updated!

    I remember reading a few posts relating to parking sensors in the past so give it a search and see if you can find anything useful/relevant...

    hmmm, could it be a dodgy sensor or a loose connection?

    You need vcds to do diagnostics on the sensors, this is the only way to sort it without swapping out sensors, the old ear to bumper/listen at each sensor may not apply to yours as its working intermittantly & so could be a sensor/s or controller at fault.

    ive got exactly the same problem, faulty sensors, there common. i just dont want to pay to get mine fixed, lived without parking sensors for 11 yrs, lol definately dont nedd um now. problem is they also need painting so ur looking at £100 per sensor from a dealer (thats what dm keith skoda charge) i imagine audi will be more. :)

    How do I do the ear to bumper test?
    And where can I find the control panel to see if the connections are tight?

    the sensors vibrate, you should be able to hear it vibrating if its working. get someone to turn the ignition on,listen, then off again. repeat the process for each sensor

    My parents S4 has a faulty rear parking sensor, meaning that the solid beep comes on as soon as you put it into reverse and the sensors don't work. VCDS identified which sensor it was, so it's just a case of getting it sorted, and making sure that you are seated as Audi tell you the final cost!

    OP, see if anyone near you has vcds by looking at the VCDS map..

    Ok I will try the vibration test and will also see if I can find anyone with a VAGCOM close to me. I shall report back. Thanks

    Thought about seeing who is going to Ace Cafe next week and seeing if anyone is bringing vcds along? Failing that, I should be there and have vcds..

    Just found the bill for my sensor,

    They gave a fault code of G204

    Parking sensor £70.25 x1
    paint £12.74
    labour £22.50
    vat £21.10
    total £126.59

    Luckily covered by the warranty, just paid for the paint.

    Hope this is a help.

    Wow John thanks for that useful info, when you say they found the fault code, did you have Audi connect to their computer to find the fault then do all of that or was it done on someone VCDS? As there is no price for diagnostics listed...

    Also as the big cost is the actual sensor, can this not be purchased elsewhere and get them to fit it or something???

    The work was done by a local audi specialist....we are spoilt for choice in MIlton keynes.so they plugged in the Audi spec computer.audi dealer said they charge to find the fault but think they said they would refund if they did the work,same as the local garage, must be so you don't run off a go somewhere else.I was charged £27 for this ( just found the paper work as you asked)


    As for the sensor you could ask stoke Audi which are on this forum or find you local TPS which are the trade arm of Audi ,just ordered some parts from them and got them at trade price......Search. Tps Audi,

    Might as well get it done as could be cheaper than a new bumper........lol,

    Cheers,

    mine never worked from day 1 of ownership, then a fortnight ago, my mate came round and had an 8 hour cleaning setion on my car with everything you can think of, suddenly my sensors work! :) perhaps a super all singing all dancing clean on the car (sensors) my just do the trick, it worked for me and i wasnt trying to fix them and cost me nothing (except my mates cleaning stuff lol)
