Mercedes-Benz 300CE Problems

Rough Running Engine Due to Misfire

A rough running motor or lack of power can be caused by a failed distributor cap or rotor, ignition wires (or their resistors), or valve cover gasket leaks. If the valve cover gasket leaks, oil can pool where the ignition wire resistor connects to the spark plug. The resistor can fail and the spark plug may not fire because of a short circuit through the oil.

Improper Temperature Output From HVAC

One or more blend door vacuum actuators may fail resulting in the incorrect output temperature from the HVAC system. Failed actuators will require replacement to restore proper HVAC operation.

The Differential May Develop Leaks From the Seals or Cover

Leaks may develop from the differential seals and/or cover on older or high mileage vehicles. Our technicians recommend a complete reseal of the differential unit when these leaks are addressed.

I'm a proud owner of a 300CE and I love it! I recently purchased the car and the more I drive it, the more I become attached to it. For a 1993 it's in excellent condition and its still running great 19 years latter. When I drive this car I feel noticed by everyone with its black exterior and stunning looks it really is intimidating. Overall, The 1993 Mercedes-Benz 300CE is a very solid car that...
