1990 Mercedes-Benz 300TE 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.

Cracked Driveshaft Flex Discs May Cause Driveshaft Movement/Vibration

A vibration felt through the center floor of the vehicle can be caused by cracked and/or shredded driveshaft flex discs, resulting in excessive driveshaft movement. If not repaired, damage to the driveshaft center support bearing, transmission, or differential can occur.

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.

1990 Mercedes-Benz 300TE Reviews

love the car but always seem to need something. Best family car EVER
I have purchased a 1990 300TE. Bodywork fab, general condition is awesome throughout. Some slight problems with the transmission, but nothing that a transmission oil change and check on vacuum pipes won't cure. All in all fantastic! My car has completed 217,000 miles so far. good for another 200,000 with good care.
It's a Benz. Like no other car. The only problem i had is the premature suspension failure (at 168K miles) Replacement parts are rather costly, and so is the expert service. It is NOT a car to take to Pep Boys.
