1990 Mercedes-Benz 190E Problems

Coolant Leak/Overheating Due to Radiator Leak

A coolant leak may develop form the Radiator due to degradation of its plastic components. Replacement of the failed radiator will be necessary.

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.

Throttle Valves May Experience Electrical Failure

The electronic throttle assembly may suffer an electrical failure. It is often cheaper to send the valve to a service center for repair that to purchase a new part.

This is what she needed and I did all the work myself: New Battery-$60 New...
stable , fun driving car. Too many problems. specially electrical. Poor head valve design caused early failure. Not what Mercedes was, should be.
I purchased my 1990 190e 2.6L 6-cyl, with 176,000 on it in Royal Oak, MI from Karl Heinz Automotive, a private repair garage owned by a previous BMW-M-B mechanic who went out on his own years ago. From the records, it seems like the previous owner purchased the car about 10 years ago with 120K on it and had it as a 2nd car.
