Mercedes-Benz 300CE Problems

Rough Running Engine Due to Misfire

Exhaust & Emissions -- Verified

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.

Electrical Issues Due to Degraded Engine Wiring Harness

Electrical & Lights -- Verified

The engine wiring can degrade because the insulating material falls off leaving the bare wire exposed. This can cause many problems depending on which wires are exposed and what they touch.

Coolant Hoses May Fail Unexpectedly

Engine -- Verified

The cooling system hoses may fail unexpectedly. The hoses can look good on the outside, but the rubber can degrade and erode on the inside. If not carefully checked, the hoses can burst at any time.

Worn seat springs/padding may cause lean or sag

Miscellaneous -- Verified

The seat springs and padding break down over time, causing a lean, tilt, or sag.

Shifter Lever Bushings May Break Causing Loose Feel/Noise

Drive Train -- Verified

The bushings for the shifter lever wear out to the point where they break and fall out. This causes excessive movement (loose feel) in the shifter lever and a clanging-type noise when changing gears.
