Iv got a 03 A4 1.9 tdi which has been remapped.
I get what sounds like wastegate chatter when backing off and changing gears. I wouldnt normally worry about this on a turbo car, but Iv been told with it being a vnt turbo I shouldnt get the noise?
Is this correct and likely to be a boost leak? Or is it nothing to worry about, I do get quite abit of smoke as well but I had put this down to the map or the egr needing a good clean.
