Mercedes-Benz 300E Problems

Failure of EHA valve may cause fuel/engine problems
Fuel leaks, erratic or rough engine operation, and fuel economy issues can be caused by the failure of a fuel system component called the EHA (electro-hydraulic actuator) valve.
High Usage Vehicles May Experience Ignition Lock and Tumbler Failures

Due to wear, high usage vehicles can experience ignition lock and tumbler failures. The ignition lock cylinder will generally require replacement to correct this concern.

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.

Once we got it back on the road I added fuel injector cleaner and drove it hard on the highway. Now the issue only appears before its fully warmed up to operating temperature.

I've had my 92' 300E with the 3 liter engine for close to 15 years now and it now has 248,000 miles on it. I’ve only had the standard repairs to perform for a car of this age (radiator, alternator, belts) all self repaired/replaced. The only small annoyance is the need to add oil, about 2 quarts/month, but I've accepted it. The car still runs strong and rides well. It’s getting close to time fo...
