    Won't idle when cold .

    OK , my 96 1.8 a4 , when dead cold , starts , but wont idle when cold , holding it about 1500 rpm it will die then just about 500rpm it will come back up to where I am holding it . A good blip on the throttle will clear it for a short while . But only after 1 or 2 mins of running time it will be fine , idles ok ( idles high at operating temp , 1200 rpm due to somebody putting a cable tie under the throtttle cable clip )but dosn't pulse .
    Now , I have had abit of a clean of the throttle body , got as much of the crap out with brake cleaner and a rag , but am tempted to get back in there and have another go and get the compressed air down a fewof the ports I can see . Wise idea ? Other than that am thinkin it can only be an electrical fault , dodgy cold start temp sensor or something . Not fully up to speed on audi engine managment stuff yet .
    Any help appreciated ,
    Cheers Cam

    Sounds like the car is not going onto choke, probably a sensor gone faulty.
    Maybe post up in the VAG-COM forum to see if anyone in your area has it to run a diagnostic.
    I have it and I don't even own an audi any more!

    The problem with common sense, is that its not that common.

    I wouldn't sell it to be honest, its worth its weight in gold, as soon as ross tech develop a BMW version of the software i'll be as happy as a dog with 2 dicks!

    They're about 270 quid to buy a geniune one.

    It'll need a new ECU temp sender, it's a pretty common fault on the 1.8.

    Should be one of these

    Hope this helps
