Mercedes benz C230 kompressor sport sedan began to leak oil into the cam magnet sensor which lead to the failure of the engine wiring harness, costing hundreds of dollars to replace.

Check engine light came on. I took it to the dealer and they told me that the O2 sensor needs to be replaced, and the engine harness needs to be replaced. This is because the cam sensor leaked and pushed oil inside the harness and now there is oil flowing in the harness. This means everywhere there is a contact of the harness there is a possibility that there is oil on it. This seems to have become a common issue now and mercedes is ignoring it. I have noticed that I am getting bad mileage because of the bad O2 sensor. The irony is that the dealer will fix it with the same exact part number only to have it leak again in 4 years.

I own a 2002 Mercedes Benz C230, which has now had 2 severe issues with it. The first issue is the electrical system - the seat control modules go faulty and start draining the battery even when the car is turned off. If you have a battery drain, this is the likely culprit. I have replaced the seat control modules a total of 3 times. This is a common problem according to internet boards. The 2nd problem is that oil started to leak all over the wires. Again another common problem according to the internet boards.
