Was bedeutet der Fehlercode?
Cylinder 6 is misfiring, and the engine control module chooses the fault code based on how serious the misfire is: either an effect on emissions or a risk of damage to the catalytic converter. The misfire can be detected already at start-up or while driving, and if it continues the catalytic converter may be damaged.
