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.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

My '01 S has a mettalic engine rattle which is most easily heard when accelerating in low gears after the engine is at operating temperature. The dealer has confirmed the rattle and checked the engine on two different occasions. They have changed the catalytic converter and the muffler. The rattle persists. Anyone with a similar problem or a solution??

POST 2Original post

I had the same issue with my '01 (non S). The dealership ended up replacing (after 3 trips) both cats and both PRE-cats along with replacing a leaking exhaust gasket - The rattle is gone! Matt

POST 3 / ORIGINAL POSTEROriginal post

Matt: Thanks for the response. This is helpful (I'm only in the second dealer trip now). chip
