Could anyone shed any light on this problem please?
Recently, my A4 has been very sluggish, low down in the revs it has no pull whatsoever, its just flat. Then when the revs build up a bit and the turbo kicks in it shoots a load of black smoke out the back then its away. I had it in to my local garage and he says it was the air flow meter. So he changed it but the problem is still there.... ? It's booked in again for Monday morning for him to have another look.
Thanks in advance
