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

I purchased my 2002 996TT 2-1/2 years ago. It had an engine rattle that I was concerned about initially, but after some forum searches, found that it seems to be a common issue with the Mezger engines. The rattle gets louder during the following conditions: 1) Car driven for awhile (fully warmed up) 2) A/C on 3) Car in neutral (6 spd manual) 4) Clutch pedal out With the A/C on, when I push the clutch pedal in, the rattle gets much quieter, possibly goes back to "normal". And when I turn off the A/C the rattle definitely goes back to "normal". I typically don't use the A/C, but used it for the 1st time a few days ago and so it's on my mind again. Just wanted to check to see if others have this issue and what, if anything, they have done to address it?
