So are you saying the additional muffler support is what the final problem ended up being with the vibration?
The vibration that occurred during acceleration went away when the DMF was replaced. (The dealer told me mine had a crack in it (?).) The vibration that occurred when the engine revved at about 3000 rpm was repaired by the additional muffler support.

Can someone please describe these vibrations; where they're coming from, where it is felt, any associated noise.
My '02 2.7 experienced a little mechanical vibration when deaccelerating from above 4200 rpm. The source was the drive train, and the vibration could be felt everywhere. I told my dealer about it during a 30k service. A tech drove it and diagnosed it as a bad DMF. I had the DMF replaced.
After the replacement, the car experienced mechanical vibration from the drive train everytime the tach hit 3000 rpm. It didn't matter whether the car was moving or not, I could rev the engine to 3000 rpm, and the vibration was present. When I talked with the service advisor about this, he placed his hand on the dash and revved the engine to 3000, then acknowledged the mechancal vibration.
The dealer then replaced a motor mount. -- No change, vibration still there, so
They pulled the transaxle and found the DFM they replaced was faulty ("flywheel will not return as per tech bulletin"). They re-replaced the DFM. (They also installed a clutch kit.) -- No change, vibration still there, so
They contacted Porsche tech support and performed several checks concerning the oil pressure relief valve and valve train. No problems anywhere. They compared like cars and found mine did not have the additional muffler support (the wire support shown as #6 in the diagram of this thread). The part number is 996-111-242-01.
With the repairs, as far as driving experience, I'm satisfied.
Porsche picked up the the costs. The dealer provided a loan car and was super.
Here's the parts list. Can anyone explain the "window adhesive"?
1 As Dual-Mass Flyw.
6 Screw M8 x 16
1 Clutch Repair Kit
8 Screw 10 x 50
7 Cyl Head Cup Seal
1 As Ignition Coil
2 ORMD-Window Adhesive (pn 000-043-203-73)
1 Exhaust Support
2 Hex.-HD Screw 8x25
2 Nut M8
1 Retaining Plate
2 Hed-Head Screw 8x30

Why was the engine replaced, and what during what year? Thank you.

Rich,
What was the diagnosis on your vibration at 3200 RPMs?
I have the same issue going on and the dealer tells me it is the DMF and want about $1000 to replace it. I am very leary of this and would like other's input on it...
I have a 2002 Boxster 2.7 with 30k miles. I had noticed a little vibration in the drivetrain when de-accelerating from around 4000 rpm. I mentioned this to the dealer during a 30k maintenance. A tech drove it and diagnosed a bad DMF. I had them change it. I got the car back and found a new and annoying vibration around 3000 rpm. This vibration occurred each time the tach hit 3000, even when there was no load. I took it back to the dealer, the service manager revved the engine to 3000, and noted the vibration. The next day, the dealer called and advised I needed a front motor mount. I had them do it. I got the car back, and it still had the 3000-rpm vibration. I returned the car to the dealer, they re-replaced the DMF, and installed a clutch kit. Still, there was noticable vibration at 3000 rpm. The dealer has requested advice from their support, I've been without the car for 5 weeks, and I'm a little worried.
Should I Get A 996?

I gave up an '02 Boxster, 2.7L with 32k miles, for an '03 911 C2 with 23k miles. The Boxster was artic silver and had a sports touring package, the 911 is seal grey. I wouldn't change back for anything. However I wish I could have kept the Boxster. Because the interiors are so similar, it's a crazy experience driving the 911. I believe driving the Boxster caused me to deeply appreciate the 911. I agree that the Boxster is a very good looking car with the top down. But it doesn't quite match the view of the 911's C-pillars from the driver's seat. And my Boxster had a quiet exhaust, but a great engine sound after 4000 rpm. The 911's sound experience is completely different and completely satisfying. My Boxster had poor gas mileage, but the cost to insure it was low. The Boxster had a soft ride compared to the 911. You might want to consider the cost of ownership of a 911. There's a difference there, too
