1996 Mercedes-Benz S420 Problems

Closing Assist/Door Lock Issues Due to Pneumatic System Problems

Problems with the pneumatic system can cause closing assist and door lock issues.

Faulty Mass Air Flow Sensor Causing Erratic Engine Operation and Poor Fuel Economy

A faulty mass air flow (MAF) sensor can cause erratic/rough engine operation and fuel economy issues. Since this sensor measures the actual amount of air entering the motor, when it fails, the engine control module (ECM) takes the wrong information and delivers incorrect volumes of fuel to the cylinders.

Insulation Degrades on Engine Wiring Harness and Leaves Conductors Exposed

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.
