1995 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.

Power Window May Fail Due to Window Regulator

One or more door windows may stop working due to a failed window regulator. Replacement of the failed regulator will be necessary to correct this concern.

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

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.

I've owned my 1995 s-420 since 1999, and have been relatively satisfied with it. My main concern is that there is a slight vibration that I cannot get rid of. I've balanced the tires, replaced all four tires, had the drive train checked all to no avail. This has been going on for the last 8 years. It looks like it is something that I will have to live with. The heating system is slow warming...
