1990 Mercedes-Benz 300E 4MATIC Problems

Electrical Issues Due to Degraded Engine Wiring Harness

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.

Engine Oil and Coolant Leaks Resulting in Fulid Intermix

Internal and External engine oil & coolant leaks can develop from the head gasket and/or timing cover gasket; these leaks should be repaired before the engine oil and coolant intermix which can result in severe engine damage.

Transmission Oil Seals May Leak on High Mileage Vehicles

High mileage vehicles may develop a leak from one or more of the transmission oil seals.
