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.

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

POST 1 / ORIGINAL POSTEROriginal post

I am already annoyed with the noise cut off on my PSE :nooo: I have read about the mod and it looks very simple to do but will it invalidate my warranty in any way? Cheers

POST 3Original post

Nope. Mine is set up without the low speed cut off which Northway's put in for me. Doesn't matter who does the mod for you as long as they are Porsche parts which your exhaust is which I confirmed with OPC west London.

POST 4Original post

The 'simpler' approach is to identify the PSE relay on the relay board (drivers footwell) and snip the speedo feed pink/grey wire, that way you won't need to mess around with snipping diode legs etc.

All done lads, she sounds a million times better now 8)
