Mercedes-Benz S550 Problems

HVAC Blower Motor May Fail

The HVAC blower motor may fail. This is commonly caused by water entry through the cabin air filter areas during heavy rain or snow. Failed blower motors should be replaced. Our technicians tell us there is no special fix for this issue at this time.

Check Engine Light Due to Faulty Camshaft Adjuster Solenoid

The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

Stalling 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.
