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 1 / ORIGINAL POSTEROriginal post

Test drove a 996 c4s today and i noticed when i turned the car off there ws like knock noise coming from sort of middle engine ti gearbox. Gears where smooth, clutch was soft and drove really tight. Im thinking maybe bd dual mass fly??? Bad engine mount? Has anyone experienced such noise before

POST 2Original post

My thrust bearing rattles when I turn the engine off........and the one before it did too.

POST 3 / ORIGINAL POSTEROriginal post

Do i need to address that and get it sorted asap. Its sounds like when the starter motor pushes out second you turn the engine off goes conk and stops probably less than a second

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