Hello dear community, No improvement, same error picture. Still misignition of Zyl. 3. Then I switched the injection nozzles between Zyl 3&4 among each other. I cleaned the throttle cap a bit. After that I turned a short lap. Same error message and no change of the error picture. So I parked the car again yesterday. Now the car hardly started this morning and ran even more unroundly than it was before. The car only stopped. Does anyone have any idea what all the fun can be about? Stuttering this morning could probably be due to the gaskets of the injection nozzles that didn’t like the one and the mounting, but what about the error message? What else could I check?
