Bought my first a2 in September. A 2001 1.4 with a glass roof. Was so impressed that I bought two more. Sister in law took that one. I bought two 1.6 fsi models. A 2003 and a 2004. Daughter got the 2004 one and I have the 2003 with 92000 miles. Nice car but with a bit of lacquer peel but red cars seem to do that.
If that was the only fault I would be happy but it has the manifold tuning valve fault and associated random multiple and cylinder one misfire. Will accelerate ok if I build the revs up gently but under any load it runs lumpy like it is misfiring. I suspect the vacum side of the flap is not operating correctly. I have exercised the flap with Vagcom and seems to work ok.
Does anyone have a circuit diagram of the intake manifold system and a diagram with the parts labelled so I know what part does what.
Is there a manual to help with maintainence as Haynes don’t seem to do one and I like to do my own servicing.
Thanks Brian
