Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I fitted new 997 actuators which are a little better, and then wired in the switch and fitted the 03 relay.

My car was fitted with the 02 relay when I bought it, and the exhaust actuators were non functional due to severe corrosion.

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.

4 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hello all, I have searched for something regarding this but I haven't found anything. My car (2003 S) has the PSE installed. It was not factory, it was done shortly after the car was purchased new (I believe). It is valved, like all the PSE exhausts, but it has no switch or relay. I bought a switch, only to discover there is no relay in my relay panel. Would there be a way to get the switch working without the OE relay? are the valves always open if I have no relay? How can I tell if the valves are open? Thanks in advance.

POST 2Original post

IIRC it works on a vacuum and opens up circa 3k rpm.

POST 3Original post

If I recall correctly, the relay is located in the drivers side footwell (uk car) on the rhs. You will have to take the carpeted panel off to reach it. There are 2 different relays. The earlier ones operate the valves automatically at certain speeds and I think the part number ends in 02. The later ones with the switch end in 03. You can buy the switch and relay from your nearest Porsche centre. My car was fitted with the 02 relay when I bought it, and the exhaust actuators were non functional due to severe corrosion. I fitted new 997 actuators which are a little better, and then wired in the switch and fitted the 03 relay. You can check in your engine bay for the presence of the PSE vacuum canister and solenoids. They're located close to the throttle body.

POST 4 / ORIGINAL POSTEROriginal post

I did a bunch of testing and determined that the relay is stuck open. I unplugged it so the exhaust valves are always open. Maybe one day I'll get it to work, but not right now...
