Mercedes-Benz E420 Problems

Check Engine Light and Engine Misfire

Failed spark plug wires and/or ignition coils can cause intermittent misfires (rough running); the Check Engine Light may also illuminate. Diagnoses of the ignition system will be necessary to determine which components are at fault.

Check Engine Light On Due to Failed Mass Air Flow Sensor

The mass air flow sensor can fail, resulting in poor fuel economy and Check Engine Light illumination.

Poor AC performance Due to Evaporator Temperature Sensor Failure

The evaporator temperature sensor can fail, causing the AC compressor not to cycle. If the AC compressor does not turn on, the AC system will not blow cold air. If the compressor is stuck on, the air will be very cold at first, before warming up.

Mercedes-Benz E420 Reviews

Great car but has a poor Electrical Wiring System
The ASR light came out and the ABS light same time came on and all gauges stopped working. When engine was shut off, it could not be started and all the lights came on.
This is a wonderful automobile. You have to drive one to know.
