Drive seat assembly on 1998 Mercedes-Benz E320 4MATIC

Th driver's seat has started to "make a pop" when any pressure is applied. I think this is in the back part, not the actual seat - but I cannot find schematics to diagnose - anyone have the seat assmebly drawings?

There may some drawings in the factory manuals. I'd guess that there's a crack in the framework of the seat or a loose bolt, or a broken spring. You may have to take the seatback skin off to see what's wrong.
Go to an upholstery shop or to a Benz specialist.
