I was looking for a solution for my Audi B7 1.9 tdi and found this thread. The problem is when I pull little harder over 2000 rpm, basically on 2nd gear, it kicks two times in a row and then it goes smooth. No error codes. But the thing I am affraid of is the DPF filter. Can it do any harm to it? And maybe a little silly question...Should this procedure clean all the components shown on the diagram above (N18, N239, N75...) or just turbo?
Thanks a lot
