Mercedes-Benz C320 Problems

Oil Seepage on Back of the Cylinder Heads

Mercedes Benz C230 models manufactured between 2005 and 2009 may have engine oil seeping or leaking from the back of the cylinder heads. This is commonly misdiagnosed as leaking valve covers.

On the back of the cylinder heads there are three, in total, plastic expansion plugs that plug access ports to the camshafts. These plugs are well known for seeping oil, and leaking if left unattended. The oil will run down the back of the engine and eventually make it to the ground. 

Replacement of these three plastic plugs is extremely simple, and should be done as regular maintenance. The recommended interval for replacement is every 60,000 miles.

Stalling and/or "Crank no Start" Due to Failed Crankshaft Position Sensor

The engine may develop a stalling and/or no start condition due to a failed crankshaft position sensor.

Clicking Noise From Behind Center of Dash

A repetitive clicking noise from behind the center area of the dash panel is usually caused by a broken stepper motor actuating arm. The actuating arm controls the direction of air flow in the climate control system. Disassembly of the center console will be required to access and change the broken arm with the updated, reinforced part.

I purchased my vehicle, the Sport Model with 18" with 207,000 miles and it is a gem. Put in new Air Filters (2) and increased mileage substantially. Rear shocks were bad but I replaced them.

I have replaced every part associated including the control center and still the problem exists. I'm ...
