    Hi Guys,

    I just got an 54 plate A3 with a rough idle when stood at the lights. It disappears when the air con is on high and the load on engine rises.

    Anyone near Leeds that would be able to help in return for a few quid?

    Thanks

    Si

    Cheers mate - will do.

    It was ok when I took for test drive but before collection they did the cam/timing belt service and seems to have caused this.

    I had an A3 previously and I appreciate most are hardly delicate when they idle but this one is awful.

    Bit of an update.

    I know some bloke through the gym who works for Audi and he quickly connected his laptop with VAG software. He said no fault codes, no misfire and timing all ok.

    That is all a relief but does not explain the intermittent stange up and down engine tone when at idle.

    Annoyingly it did not do it when he was taking a look :(
