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.

Mercedes-Benz 400SEL Problems
Problems with the pneumatic system can cause closing assist and door lock issues.
High mileage vehicles may develop a transmission fluid leak from one or more of the oil seals.
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.
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.
