1990 Mercedes-Benz 300D Problems
Due to wear of the internal drive gear, the speedometer can stop working.
A knocking noise from the front end can be caused by cracked strut tower bushings.
The bushings for the shifter lever wear out to the point where they break and fall out. This causes excessive movement (loose feel) in the shifter lever and a clanging-type noise when changing gears.
The engine wiring can degrade because the insulating material falls off leaving the bare wire exposed. This can cause many problems depending on which wires are exposed and what they touch.
