Please could an S3 owner try the following for me as i think i may have a engine fault. When the car is idling can you remove the oil cap and see if the engine tries to suck it back on as your pulling the cap away, and also does the engine start to run rough, also when you pull the dipstick out about an inch it also splutters. Would be kindly appreciated before i give audi a call, my warranty runs out in a few weeks!!
