Ignition System: Description and Operation

V6 DFI Engine

Ignition Coils - V6







The V6 engine still has static high-voltage ignition distribution with individual ignition coils directly on the spark plugs. The DME control unit activates the individual ignition coils individually in the firing order 1-5-3-6-2-4 for each cylinder. The individual ignition coils in the Cayenne V6 have an integrated output final stage, but unlike the Cayenne V8 engines, the diagnostic function is integrated in the Motronic control unit. If an ignition coil fails, fuel injection for the affected cylinder is deactivated. This can happen on up to two cylinders.
