1994 Mercedes-Benz E320 Problems

Engine Performance Problems Due to Crankshaft Position Sensor Failure

The crankshaft position sensor may fail. Symptoms of this are: The engine will crank—but not start—especially when the engine is warm. The car may start again if it is left to cool off, but it may run roughly or have poor performance.

Malfunctioning Regulators May Cause Blower Motor Failure

A malfunctioning HVAC blower motor regulator can cause the blower motor to operate below the requested speed or not at all. Updated regulators are available; the blower motor and cover need to be replaced at the same time to upgrade the system.

Failed Exhaust Catalytic Converter May Cause Rattle From Beneath Vehicle

When the engine is running, but the vehicle is not moving, a rattle heard from beneath the vehicle could indicate that one of the exhaust catalytic converters has failed. The substrate (the internal part of the catalyst that reduces emissions) can loosen and bounce around inside the canister section of the converter—the defective unit will need to be replaced. If this problem is ignored, the substrate can break down and reduce to a size that plugs the outlet pipe, which will cause a sudden loss in power.

I have to give the Germans their well earned right as very well engi...
It is a great car which gets great gas mileage and is really comfortable. the performance is awesome for a sedan. The repairs can be expensive but do not occur often. 3.6 liter inline 6 engine. 6 gallon gas tank and 2 gallon reserve tank. Great car!!!
