83 240d buzzing dash

Hello,
I have a recurring issue where the dash in my 83 240d makes a buzzing/vibrating noise at higher speeds. Specifically its the clear plastic in front of the gauges. If I press against it, the buzzing disappears. Im not sure if there is a spot I can tighten up that would quiet things down. I was considering trying to slip in a thin piece of rubber or something similar to try and stabilize things. Has anyone experienced this? Any help would be really appreciated! Thanks!

Edit: Just to elaborate a little more, the buzzing seems to come from the upper part of the clear plastic, where it joins with the black dash.

The dash is a friction fit and doesn't really "tighten up."

The whole cluster may be loose and could simply be pushed in more. Sometimes the heavy felt insulation comes unglued and makes seating it snugly difficult. You might have success by removing the knee bolster and 'guiding' it from underneath (I recommend wearing goggles if you're under the dash looking up - lots of crap up there) while someone gently pushes from the front. That may seat the whole unit.

Or, if someone pulled the clear lense while trying to remove it, it's possible the lense has come unglued/cracked away from the black housing and that's what's vibrating. If that's the case, then you can remove the whole cluster and glue the loose section back to the case. Don't be tempted to completely remove and re-glue the clear lense, just some super glue on the loose part.

If you remove the cluster and this is your first time (assumption based on post count) then search for some threads about the speedo cable and the oil line. You don't want to break it, but you want it to go back without leaking.

Thanks, those are some great suggestions! It wouldn't surprise me if the issue is the lens has become partially separated from the housing you described. It certainly looks that way.

I'll try digging around tomorrow and see how it goes. Really appreciate the help.

Use a 13mm on the back of the oil gauge fitting to take the stress of it as you use the 10mm to loosen the line.

DO NOT start the engine once this oil line is loose and or disconnected. you will get a lap full of black yucky oil.
