I would like to discuss the subject of the ignition coils which sit on top of the spark plugs. The factory Bentley manual for my 2002 Passat
1.8T specifies using a special tool to remove these coils. I read that after I replaced the spark plugs without the special tool. Soon afterwards, 2 of the 4 coils failed. The failed coils were not the original. The original coils failed (without being removed) and had been replaced by a VW campaign. The new ones have yet another part number revision, so I wonder if the second set had a defect too. Anyone have any experiences or knowledge on this subject?- posted
