I have a 2006 3.2 Cayenne. When I accelerate normally the engine sounds slightly like a diesel until i reach 1900 to 2000 rpm. If I accelerate fast I also get loud engine rattle noise at around 3000, if I drive normal the rattle is not very prominent. No power loss shifts smooth. The engine rattle noise does increase with rpm but disappears around 4000 rpm when car shifts. No rattle at 3000 rpm normal acceleration. Any thoughts?
I'm getting a weird buzzing noise (buzz/whine) when above 4000 RPM. It's a 997S 1st gen no mods, with about 70k on it. It sounds a bit like the car is struggling at anything past 4000 RPM.. It happens in gear and in neutral. When its hot and cold. if anyone has any ideas of parts I should look at, that may be causing this, please let me know!
I'll post a video of the sound in the next couple of days too, so you can hear what it sounds like.
Thanks a lot!

With my Boxster S, it was the lateral arms... the ones that goes front to back. In the 197K miles of ownership, I think I replaced at least all of them twice and a few three times.
My 2009 C2S has a clunking/rattle in the right rear. I had it up on jacks and could not find it. I checked the three bolts on the top of the struts, I put a tire iron in there and twisted and wedged and no joint/bushing moved more than the others.
I am very sure it is a control arm. So, unless someone in Philly has some chassis ears they can lend me for a day, I want to just replace the most common offender. 997 331 043 01
So, which rear control arm goes first?
Anyone know the torque values for this part?

I'm sure this has been covered, and maybe I'm blind, but I've got quite the cold start rattle and want to look into changing out my tensioner's, the car is an 01 c2 cab, factory IMS, 97k miles and runs great. Is there any guide or maybe some tips to doing this? help would be appreciated!

I have a 2012 C4S with a sunroof. When going over rough pavement I hear a distinct, persistent rattle -- more like a mechanical buzzing sound -- coming from the area of the rearview mirror and dome near the mirror. It may or may not be the mirror or something in the dome -- perhaps it is something under the headliner in that area -- but I am sure the sound is coming from that area (I have cupped my ears and listened and there is no doubt the sound is coming from that area).
My dealer observed the problem and thought he had fixed it -- by applying tape to plastic parts that may have been rubbing against each other -- but the problem persists.
Has anyone experienced this problem and discovered its source?
