The 2011 pegout misfires at idle and the engine fault lamp is on. I had the brain check the 4th cylinder, it gives a combustion failure, I took a few repairmen, they all spoke differently, it could be from the valves, it could be the injectors, the ignition coils and spark plugs were changed. It is said that there is a Mini Cooper gasoline engine in the vehicle and no one approaches because there are problematic engines.
