Those of you owning 1.8T cars from the VAG group, might be interested to know there is an official workshop campaign in effect which mandates the change of your (old) coilpacks with an updated revision. This change is for free (!) and if you service your car with a dealer you should normally get it automatically. Otherwise, or just to be sure, you can call/visit any dealer, ask about it, and they will most likely do it for you. Note: the car doesn't have to be bought from that dealer or even Switzerland.
Enjoy your new set of coilpacks
