My indy checked the issue on a lift with a stethoscope and diagnosed it as a failed baffle in my passenger side PSE muffler.

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.

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

POST 1 / ORIGINAL POSTEROriginal post

I've been hearing a light ticking sound coming from the rear passenger side when slowly rolling in parking garages or next to walls. The ticking immediately stopped when the car stopped rolling. Ticking was present while rolling in neutral and in drive. Engine ran quietly at idle. My indy checked the issue on a lift with a stethoscope and diagnosed it as a failed baffle in my passenger side PSE muffler. They said the ticking was a resonance from the failed baffle. I'll probably get the muffler fixed/replaced at some point if it gets really bad, but just wanted to post this for others who may have this issue.

POST 2Original post

Are you sure there is not a nail in your tire? If the ticking noise only happens when the car is rolling, it probably has a nail/rock or something in your tire tread.

POST 3Original post

If only "Ticking noise" was so easily resolved ! After all the doom-talk usually involved in a Ticking Post , it is amusing to be reminded that there are innocuous reasons for ticking on an M96 engined Porsche. No acronyms required - good !

POST 4Original post

Ticking noise when rolling. In this case I could actually feel it.

Exactly! This is why I posted -- having fears of bore scoring or broken lifters, and it turns out to be "just" the muffler. Which is in fact ~$1,500+ to replace (I understand you can't buy a single PSE muffler), or a few hundred to find someone to cut open and re-weld the baffles. It is not a rock or nail; the ticking is in time with the idle, and the cadence does not slow or speed up depending on speed.

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