Foam type insulation on plastic belly pans under W124
When I took my plastic belly pans off recently, I had to scrape away the foam insulation put there by the factory.
The 1" of foam was oil soaked and beginning to turn to mush. Any idea what was used and what I might be able to replace it with? Thanks It's a late W124

man - Im looking for a used set of those in the yards, the new ones are $$$$$$$ - and you can use the above insulation perfectly. Seen an MB mechanic do that too.

Edbso - thanks for the links but the first link takes me to a vacuum cleaner..
Jeremy - very happy I still have them. I check all the screws every time I'm under the car as they tend to back out from vibration. The front pan is a bit worse for wear as it tends to be the lowest point which scrapes especially when leaving driveways. The price is just stupid for replacements and is calling for aftermarket.

I used this type of foil insulation on mine. I agree with Jeremy, it doesn't do much for sound, but streamlines the underside of the car. Why would you want to quiet down the sweet sound of the OM603 anyway. It's not like a 617 tractor motor.

I tried a form of foam sound matting but found that it was attacked by diesel and ended up removing it. In any case, I noticed no difference in sound levels and the stuff I used was heavy, made the belly pans harder to handle. There are many other materials to try but most of us have ended up with no lining at all and the belly pans still work fine. Just be thankful you still have belly pans. Although Mercedes calls them "sound control" panels (I forget the exact term they use) they are really for streamlining the underside of the car and for temperature control in the engine compartment.
