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.

Discussions that contain suggestions: 1

0 original-poster resolution reports. Counts can overlap; they are not unique people or a success rate.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

I have in the past removed the levers and freed them up and all has been working well for some time, however when I went for a run yesterday no change in exhaust noise when I push the switch.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

I have the "adjustable noise" system which is operated by the electro/ vacuum system moving the bypass flaps. I have in the past removed the levers and freed them up and all has been working well for some time, however when I went for a run yesterday no change in exhaust noise when I push the switch. A look underneath confirms that nothing moves when the switch is pressed. The levers are free and all vacuum pipes look good (as far as I can see) so I'm fairly sure its the electrical part of the system. All connections are fine but car electrics are not my strongest point. I can't find any reference to a fuse, is there one? All assistance appreciated! Many thanks.

Most likely to be vacuum, might be mechanical, unlikely to be electrical. Test and prove the vacuum bit first.
