Been reading these forums for a few weeks, just decided to register as I have now got an A3 2.0 TDI Sport.
Love the car - absolutely awesome - better than my Golf 1.9 I just got rid of :D
Anyways, basically I wondered if any of you guys could help with this.
I've noticed that when I put my foot down there is very often a kind-of delay / lag with the boost from the Turbo.
It's kind of like it starts to boost for a second, then goes flat for a few moments then carries on boosting. If this makes sense?
Could it be the MAF sensor? Can this be cleaned? Or if not would you recommend a cheap-o one from eBay or the genuine Bosch one?
Or could it be something like an injector?
I've noticed that when starting up it puffs out what I think is probably faint blue smoke but only for a minute after starting up.
Thanks in advance!!
Oh- and it's the 8P chassis - 54 reg. Thanks!
