These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

4 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

hi! Can anyone help me please. My 996 Mk2 facelift 2002 MY when radiator fans starts working especially in high Revs but in the idle too the car it has vibration. Or the same think exists when the Air con. it turns on. I have changed all coils new and the engine mounts are okay. Anyone has the same experience to help? thanks!!!

POST 3Original post

Tell us more about this facelift. Maybe some pictures?

POST 4Original post

To clarify, does the vibration feel like engine or is it from the front of the car like an unbalanced fan blade? I'm guessing that since you mentioned coils and engine mounts its the former. I've found my car to stumble slightly at idle when the A/C compressor engages - all of my previous cars have done similar with the exception of my BMW. Is it more severe than that?

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