okay so the engine/emissions light came on the other day, up until then it was perfectly fine! So now the light has gone off however, now when I start the car there is a bit of a bang and a few less vigorous bangs afterwards for a short period then all is fine?!!?
It sounds like the same problem as this Engine knocking on start up!! Help!!!! if it helps?
I've not had diagnostics however I have a sneaking suspicion that it may have something to do with the intake manifold flap,would this cause this problem, it could be the cause for the emissions light??
oh and its a 2004 a3 2.0tdi BKD engine
any help would be appreciated.
