1992 Mercedes-Benz 500SEL Problems

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.

Tandem Hydraulic Pumps May Leak From Either Section

Some models have tandem hydraulic pumps—one section for power steering and the other for suspension adjustment. These pumps are prone to leakage from either section.

Window Regulator Failure is Common

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.
