2007 Cayenne 4.8 s Pooo8 code

[Dee_70]

I've had problems with my 2007 4.8S Cayenne. At full operating temp I get delayed starting and then the EML came on. She then started stalling and has also started misfiring. Normally she starts on the button from cold and stalls after about 20 mins of driving but then doesn't stall again after the restart. My mechanic pulled a P0008 code and he has suggested replacing the VVT solenoid. I was also going to replace both the cam & crank position sensors at the same time. Has anyone else had this issue and, if so, what fixed your issue? Also is there just one VVT solenoid per bank?

A P0008 trouble code indicates an Engine Position System Performance issue in Bank 1. This means the engine control module (ECM) has detected a problem with the alignment or synchronization of the crankshaft and camshaft(s) in the first bank of cylinders.

 

This can be caused by:

A sticky or dirty VVT solenoid - I would change the oil and see if it gets better.

Or depending on the mileage the VVT solenoid might need to be replaced.

Thank you. I'm having the solenoid replaced next week together with the cam position sensor & crank position sensor, fingers crossed that will do the trick
