Hello all! On the 944Turbo I hear what appers to be the engine knocking when accelerating, just as the car shifts. When I make a kickdown, the car also knocks a couple of times, just before the AT downshifts. What could be causing this pinging? I´ve checked the codes and have only found an intermitent 1-2-1 code, which I think is due to a poor connection to the air sensor. There are no further codes. How can I tackle this? Thanks for your help!
