Mercedes-Benz E500 Problems

Erratic Engine Operation and Poor Fuel Economy Due to Faulty Mass Air Flow Sensor on Mercedes-Benz E500

Problem Description and Possible Solution

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.
