Maybe I need to listen to it from outside or test using a decibel meter!

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

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

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

0 acknowledgements have no verified action link; they do not establish a repair result.

POST 1 / ORIGINAL POSTEROriginal post

I can't hear any difference with the button on or off, is there supposed to be a big difference? I've checked the brown cable in the engine compartment and it's still connected. Also just did the diode cut and now there's no nerfing from 25-40mph But the PSE button still doesn't seem to do anything...

POST 2Original post

There is a big difference between silent and loud. The default position of the valves on the exhausts (no vacuum applied) is open = loud. Only when you apply vacuum, the valves are pulled shut. A frequently failing part is the electro valve. Or, they stay closed all the time = No vacuum = loud But I have seen cases where the electro valvee stays open all the time= silent Vacuum leaks or a leaking actuator are other options.

POST 3Original post

You can definitely notice a difference in the tone with your foot down. Not sure how I'd describe the change as I didn't think it was that much louder. Seems more like the depth of the noise changes.

POST 4Original post

On the quiet setting mine is 98db, on the loud setting is 108db (Goodwood's noise meters). You should be able to hear the difference!

Seems more like the depth of the noise changes. Interesting, that's kind of what I'm hearing as well, a difference in noise rather than the actual loudness. Maybe I need to listen to it from outside or test using a decibel meter!

POST 6Original post

I've only heard it on a test drive this week. All the others I've driven didn't have the PSE. Try with the windows down as a start.

POST 7Original post

But crucially does it go quicker in either mode??!!

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