I drive a North American SLK 350, 2015 and have had to replace the spark plug ignition coils on two cylinders lately. #6 took me about 3 hours. Anyone else experience coil issues, thought these would last longer.
Your car employs MSI multi spark ignition which may put more strain on the coils. Its usually the ones at the rear that fail as they run a little hotter in the engine compartment
