Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I just purchased my 2002 C4S with 39,000 miles in February and it has the PSE feature. Yesterday morning, I got into the car, started the engine and the PSE light was on (meaning sport exhaust is turned OFF). This light is never on when I start the engine. I didn't have it on when I last turned off the car either. When I tried to turn it off, it wouldn't turn off. I pushed the button several times and drove the car for about a minute, pulled over and shut off the engine. When I restarted the car, the light was on again. This time I was able to turn it off and the car got louder. I have read that the PSE system works on a vacuum system. Is it possible the valves were sticking or the vacuum system is failing? One other thing I should mention, the previous owner had the catalytic converters replaced at 32,000 miles becuase they failed. He said Porsche replaced them under warranty. Maybe the mechanic that replaced the cats didn't hook something up properly??? Anyone else experience this issue before?

POST 2Original post

sounds like an electrical issue located at the PB area.... pull the PB out and and wiggle the wires or look for a short in the wires....

POST 3Original post

I agree with Ferd (redridge) that it sounds like an electrical issue. If the vacuum line(s) had come loose the light in the PSE button would not be illuminated. You may also want to check for loose PSE wires in the engine compartment.

This is a source reference. Confirm exact model applicability in the original material.
