I have a A3 1.9 TDI and when I start my car up either in the morning or in the afternoon. I can drive my car down the road and when I put my foot down the car doesn't seem to pick up very wick (turbo boost). But If I run the can arouns for a couple of mins and put my foot down the pick up (turbo boost ) is all there. Does anybody have a answer for this question? The car has done 85k now, would this make a difference?
