wow 997 fault detection hahaha

The problem with intermittent problems is catching them in the act. If it left no pending codes that is unusually.

They likely need to connect the PIWIS tester and then "rain" water on the car with a hose.

I just talk to my local service guy in Porsche dealer he told me that if we don't have any codes 95% chance that the high pressure fuel pump is bad . Any ideas ??

did not change the pumps yet . Now when you start the car it runs only for about 10 to 20 seconds . When i am under the car i can hear the pump running (passenger side) , then the pump stops and 5 second after that the engine shots down. Any help before i send it to dealer ? :renntech:
