Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

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.

7 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.

Hi all, In the long series of mysterious rattles, please allow me to add the one in my 987.2 Maybe one of you knows what it is. Here it is (scroll to 55 seconds): https://www.dropbox.com/s/1741qgn36as8wtb/geluid_rechtsachter.m4a If you hear somebody mumbling in a weird language, that's me, in Dutch The rattle only occurs at higher speeds (> 120 km/h or 70 mph). It is not affected by road-surface or RPM. It is not caused by the privacy screen or by the storage compartment, nor by the strut that holds up the trunk (verified that). The sound seems to originate from beneath the window behind the passenger seat. Weirdest thing: it has come and gone, and come back. I can't find a pattern...

POST 2Original post

I wonder if it has to do with the engine compartment fan? If the bearing is shot or the mount has broken or something like that, the airflow into the vent at high speed may cause a vibration.

POST 3Original post

The rear spoiler goes up at 70mph, right? Maybe something with the mechanism? Try manually extending the spoiler with the button and see if you can replicate the problem at lower speeds with the spoiler up.

POST 4Original post

Good point, I have been looking for things related to airflow to check. Yours is another candidate.

POST 5Original post

Hadn't thought of this yet, indeed that is the speed at which it extends. I'll check that as well.

POST 6Original post

Checked the vent and the spoiler to no avail. Tightened a nut holding the vent in place but it was barely loose. Any further input welcome, the saga continues

POST 7Original post

Found it. As quite often with these things; it's really quite simple once you understand it It was the rear bumper part whose screw had come loose a bit and was flapping in the wind. Clip: https://www.dropbox.com/s/99o6kcj3lhcngcg/IMG_7146.MOV?dl=0
