Can anyone tell me the positions of this flap at certain revs. Should it be open at idle and close up the rev range? Can anyone tell me how to test this?
The reason i ask is i have just revo'd my s3 facelift yesterday but now the manangement light comes on and shows fault code p0300 random misfires and p0303 misfire on cylinder 3 this only happens in 4th gear at around 6700rpm. I beleive others have experinced this problem, the car has only covered 3k so dont really see it being a injector issue? Any help would be great before i have to contact the dreaded Audi customer services.
