I was driving on the highway last week and suddenly the engine starts cutting out very badly. Got it towed to my house. Pulled codes and came up with Miss fire on cylinders 654&2. Now it won't even start. Is there a shraider valve on the fuel rail any where to check fuel pressure or has anyone had this happen? Only have 90k on it and have taken really good care of it. Thanks

Yes - there is a valve. I'll move this thread to the real Cayenne forum - although I suspect by now you've gotten it fixed somehow.
