Hi all. Have just bought a 2001 A3 tdi engine code is ASV. Since buying the car the idle has gone crazy and when warm it varies hugely between about 750 and 1050 rpm. Ive checked around, the one obvious fault apprears to be a small vacumn pipe which is going nowhere, its coming off the vacumn pump on the bulkhead and heads towards the drivers side, i cant see any obvious places for it to go with the only possibility being a small stub end of pipe sticking out of the bulkhead where this pipe could possibly head. Anyone got any thoughts on this pipe? i know its a bit vauge sorry. Before i start pulling the inlet manifold off im going to run some diesel purge through it see if that makes a difference. If it is relevant the ESP light is constantly illuminated
Any thought would be appreciated.:beerchug:
