2015 S63 Coupe - Jerks violently during heavy acceleration
Hey guys! I am having a problem with my S63 coupe.
The problem showed itself after an ECU flash procedure.
During heavy full throttle acceleration on a high-way, at high RPM the car starts jerking violently, and feels like power gets cut off for a second.
The tune service people recommended to go to a dealer to update the fuel module computer. But there is no update available.
Maybe someone had a similar issue? Please help.
Thanks
Alex

This sounds unrelated to the ECU programming and the timing could be a coincidence. I believe you should have a 217.377 with a 722.9 that has a wet clutch therefore there is a possibility that if you carry out an extended adaptation of the wet clutch whilst driving this should rectify it. There should be an tips document in which your local dealer can search for and follow to hopefully fix your issue.
