"Transmission Intervention during Gear-Shifts
(EGS only)"

War ist die problem, steurgerät oder zündspulen?

Sometimes the gearbox works really great, all shifting happens smoothly. Sometimes 3rd gear is really hardly shifted, with a loud bang.
Once the car left me on the road(lots of humidity, hard rain), the engine didn't fire all 8 cylinders, but when the ignition coils dryed up, it started working perfectly.

The ignition coils do have crackings on the rubber-parts, i have cleaned all oil away from the spark plugs, spark plugs are all new. I have also changed the leaking engine cover seals.
