Creaking sound in the trunk - not the dead body problem
it is driving me nuts, a creaking/rattle sound when going over bumps, etc...has been progressively gettign worse with mileage (now 9k). It is not the same problem as the "dead body in the trunk" problem that sound like a thumping noise from the airmatic suspension discusses in earlier threads. I have checked spare and battery to ensure they are not lose, they are not. I have also tried to adjust the bumper stops on the trunnk lid, it made no difference. However, there are also stoppers on the trunk lid that can be adjusted via a hexagonal screw, any ideas if this may do something? Any other ideas.
I will keep my ears open and if I find something I will post.
Its obvious the unibody of our cars stink and is not torsionaly as stiff as a sports car should be. Another Mercedes undercut in design take a E320 chassis and load in a hugh motor viola a half made sport sedan.

When, what speed dose it happen, is it worse as speed increases?
Is there a speed when it goes away?
Have you changed the ride hight?
Is it louder with the car empty or fully loaded?
What makes it worse a right turn or left turn, accelerating or breaking?
Do you have the pano and the folding rear seat, how about the rear sun shade what position open, closed, up, down are they in when you hear the noise?
If you have the trunk closer is it working properly?
Record it and find the frequency and determine what moves/oscillates at that frequency.

2. as above
3. Car is stock. I have tired all Airmatic settings and it does not make a difference.
4. Similar noises whether car has one or more persons.
5. slow turns on slopes where the cars frame is being torsioned
6. I have both pano and folding rear seats. Rear seats seem to be fully latched. I have suspected the folding rear seats to play a part here, but cannot figure out how these would make noise unless they were not fully latched.
7. I have trunk closer and it work properly. I have changed the height of the rubber stoppers on the trunk lid (by screwing them out about 2 full turns). This seemed to help a little bit.

Ok, that is likely the pipes hitting the heat shield. Just get under there and make sure you have room. you can try to find it by reving and letting go to instigate the rattles. Did you have your resonator deleted?
