Mercedes-Benz 400SEL Problems
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.
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.
