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.

1993 Mercedes-Benz 400SEL Problems
The electronic throttle assembly may suffer an electrical failure. It is often cheaper to send the valve to a service center for repair that to purchase a new part.
Problems with the pneumatic system can cause closing assist and door lock issues.
Due to the size and materials of the brakes on these vehicles, the brakes start to squeak around the 50 percent wear point. The brake rotor surfaces become uneven, causing a lip to form at the outer edge of the rotor. Because of this, the rotors are usually replaced when the pads are worn (pad life varies depending on driving style and terrain).
Oil feed tubes break and fall into the crankcase (engine) and the tappet becomes noisy
(ticking), resulting in degraded idle quality. Our technicians recommend
replacing all of the tubes at the same time, broken or not.
