[Stoffle32]

Okay All, had a Vag check done last saturday, thanks to Darren(Atomix) for doing it for me! got some errors on Engine II! as well when i start up the car, when its cold, or when the automatic choke comes in it sounds really strange and misfires what could be the problem, only does it on start up when automatic choke its on?

Several of those are intermittent errors - do they come back when you clear them?

I see you still have SW 0020 - which is very old I think? My 2006 RS4 came with SW0050, was updated to SW0080 in 2007 and I am just about to have SW0090 installed.

Im just taking a guess in saying thats the software! here in SA the dealers are useless they probaly wont even understand if i told them to upgrade it to SW0090 or 80, its bad! I have not checked yet, if they come back will this wknd, but everytime, i start the car it, sounds strange like its missfiring! and like i said before came back from the dealers with the airbox and pipe disconected! and according to Ross tech, a misfire can be caused by Air Intake System leaking, so I might have not put it on as tight as i thought! will check! and also its on a different cylinder everytime very strange

8E1-910-560-B @ 0040 is current in this case, keep in mind that the software versions are part number specific and part numbers usually change during the model years.
