Just got my car back after a second go. They did the following: "Tightened seat belt spool mount at roll cage. Tightened B-Pillar components on both sides. Applied krytox to support straps at B-Pillars". So far so good. The noise appears to be gone. I'll keep my fingers crossed. Btw, I also got the clear parking lights. Nice look for only $40. Jim
I just started hearing this same sound you guys are all describing. My thoughts are similar to Masterbm...its a disturbing sound since it just started after I crossed the 6000 mile mark on my '06 987. Also recently noticed that after I drive the car for a while and go on idle, there is a crackling sound, kind of like leaving a coin in a dryer. I guess its time to see Mr. Service.
I took my car in this morning for a follow-up. The technician and I went for a test drive and he was able to hear the noise. It looks like the noise is coming from the entire back side, not just the driver side roof. He said the problem was that part of the frame was hitting against the cloth. When it gets real cold, apparently the cloth gets real hard and causes the noise when it bumps against the metal. He added some kind of tape between the parts that's suppose to reduce the noise. He went for another test drive but unfortunately, today was the rare day in San Diego when it was raining so he had a hard time discerning between the rattling and the rain drops hitting the top. He asked that I come back when its sunny so they can nail the problem. For the first 15 minutes after I left the dealer, the sound was pretty much gone (except when I go over really significant bumps). But as I was pulling into the office, the noise came back consistently. Quite obnoxious. So the saga continues...
I had this pretty badly on the passenger side and only on big bumps on the driver side and only when it was cold outside. I took it to the dealer and of course it turned out to be over 70 degrees that day so it was quiet as could be. Only does it when the temperature is in the 50's and lower it seems. Anyway the dealer opened the top about a third of the way so the fabric was loose enough around the rear side of the window to pull back a bit a look inside. He ended up lubricating what looks like a rectangular piece of fabric close to the edge of the top and appearing to protect the metal components from rubbing on the plastic parts that go around the window. First cold day and problem solved on the passenger side. Now it's gotten worse on the driver's side. I lubricated the same thing wih pure silicone spray and it helped a bit. Now I've used the same spray to lubricate the plastic components that form around the window where they meet and it's better but not completely gone. The dealer said it's an issue but they don't know what it is or have a fix yet. Guys, I took my car into the dealership yesterday and as Popolu predicted, not much success. They said that they couldnt hear anything coming out of the driver side but thought there may be a sound coming from the roll bar on the passenger side. They worked on the roll bar (not sure what they actually did) but, of course, as soon as I drove off the lot the noise came back in full force. I'm really not sure how they missed the noise since its quite obvious (and obnoxious). I'm going to send the dealer this set of postings and perhaps take my car back. Hopefully some of the tips by Popolu and 1JB can steer them in the right direction. I'll let you guys know what I find out.
Hi there, I have a 2006 987 and I think I have a similar problem. The noise is more of a clicking/rattling sound (vs cracking) and it appears to come from one of the joints on the driver side of the roof. I'm debating whether to bring it in to the dealership to look at. Any advice would be appreciated. Thanks. Jim
