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.

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

Have tried cleaning with WD40, Back to Black etc but it appears to be the actual plastic that has changed colour, and as you can see it goes right under the car above the exhaust.

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.

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

Noticed the plastic surrounding my exhaust was a bit lighter a few weeks ago and is now looking really ugly. Not sure what could have caused it. Have tried cleaning with WD40, Back to Black etc but it appears to be the actual plastic that has changed colour, and as you can see it goes right under the car above the exhaust. Has anyone else seen this or got any suggestions ?? Thanks in advance Al.
