Cleaned my throttle body with proper throttle body cleaner and the MAF with electrical contact cleaner.Also got the throttle body re-aligned with proper VAGCOM.But then again mine is the ADY engine 
Any difference in stability in idle with the MAF sensor cleaned? mine is still largely uneven (swings around 800-850 rpm when idling warm) after proper throttle body clean and breather hose change.. Thinking it's probably the MAF sensor or my broken lambda sensor . sorry if I'm hijacking OP's thread
