2003 Mercedes-Benz C230 Engine cooling Problems

“The check engine light goes on, the next day I go to independent mercedes shop. They tell me my o2 sensors are bad. The reason that they are bad because of the cam sensor at the top end of the motor was leaking. The whole time it was leaking I didn't even know. Then the bad new everything has been coated in oil such as o2 sensors that is it gives out the check engine light. The engine harness is also coated in oil.”

“This is a new Mercedes-Benz C230 compressor engine with one thousand miles. Last month a sulfur smell emitted from the exhaust while warming. I was told this is normal.

I have noticed that I am getting bad mileage because of the bad o2 sensor. …”
