2015 S63 Coupe - Jerks violently during heavy acceleration
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
