Porsche Repair Questions? Ask a Mechanic for Answers ASAP
hey there thanks for the question.
I apologize, the Cayenne has a relay/switch under the drivers seat that needs reset or replaced when in a collision that causes airbag deployment.
It will be under the drivers seat in front of the battery and if it is the type that resets it will be a yellow switch.
The main question would be did the car start for 10 seconds just on the initial start after repair or will it continue to start and run then for 10 seconds and die?
The best way to KNOW if the rest switch is the issue is to check the jump start terminal under the hood. Left side of the engine compartment remove the cover and test for power. If there is power there then we know the relay or reset switch is not at fault.
