Mercedes-Benz CL500 ProblemsStalling and/or "Crank no Start" Due to Failed Crankshaft Position Sensor
The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.
Other than a defective motor, a bad switch or blower motor resistor assembly can cause an inoperative heater blower motor.
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.
