They replaced some metal parts in the frame with some others that didn't rattle.

They all do it, and the predilection changes with outside temperatures.
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.

Greetings,
I have an 04 C4s Cab. Ever since it has been new the top has rattled. I have had it in to the local dealer 3 times to find the rattle.(just got it back after 1 week)They found a technical Bullitin from Porsche that dealt with this problem. They replaced some metal parts in the frame with some others that didn't rattle.
WRONG!!!!
!
They all do it, and the predilection changes with outside temperatures. Only the most fastideous and repeated efforts at employing the TB will clear it up. I have given up on mine.......On cold days it pops and snaps to distraction, especially going over any bumpy surface.......
I can only speak for myself, but my '04 C4S cab has been rattle free from day one. There was a slight squeak in the frame above the driver's door, and the TSB fix (listed on renntech.org) took care of that with a little silicone spray. Other than that, it's as tight as a drum. Best soft top I have ever had (including Ferrari, Aston, many 911s) other than MB. I suggest you find another dealer with a resident rattle expert--this is definitely not something to accept. I've sold many of my cars for having squeaks and rattles that didn't go away (especially glass roof Targas!).
This is a known issue and is solvable. My '02 C2 cabriolet had that problem when I first got it. It turned out to be cables in the top rubbing together. The dealer wrapped them in tape and I've never had a rattle since. I posted the work order info in response to an earlier thread on this same subject. Do a search and you should be able to find it (I don't have the info with me at the moment).
My C4S has had zero rattles as well. I have about 22,000 miles on it now it's as rattle free as the day I picked it up. The only thing I noticed is the windscreen creaks sometimes but that's expected.
ymmv,
Rob
