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.

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.

POST 1Original post

Could be something as straight forward as the exhaust heat shields, particularly if the engine has been removed and some of the mounting points have been lost to corrosion.

POST 2Original post

The file is no longer available. I would take it back to the garage and explain your concerns, and at the same time tell them that you have rerurned reluctantly due to past history of problems.

POST 3 / ORIGINAL POSTEROriginal post

Hi all I just had the cylinders 4-6 replaced on my 2006 997 C4S as they had scratches after 70K miles. when I got the car back I notice that whenever it's idling now the engine emits a rattling sound. Seems to come and go in the sense that it gets louder and quieter but I'm not sure I've quite identified the circumstances fully. Definitely rattles loudly at start up when the engine is cold, so I suspect the oil getting warmed up is part of the reason it gets quieter but it's not going away completely. Normally I'd just take it back to the garage that did the work but they've worked on the car three times (under warranty) and each time the original problem gets solved the car comes back with a new problem, and this is a case in point. Got the cylinders replaced but now I've got the engine rattling like crazy every time I stop at traffic lights, loud enough to have everyone walking by wondering what the noise is. anyone got any ideas on what the problem is? here's a video of the sound https://vid.me/bfh Thanks Edited by PrimeArchitect on Wednesday 5th November 13:18
