twisted c230

Hello all,
Like it says I have a 03 C230 kompressor and it keep going into limp mode. It happens in cruise on the freeway and in town. Turn it off and it's fine for a while. I have a Auto boss scanner and also a cheap scanner. Here are the codes from the Auto boss
1: P200b-04
2: P2021-02
3: P2022-02
4: P2017-02
5: P2015
6: P2033-01
7: C1022
8: C1024

Cheap scanner

1: P0141
2: P0414
3: P0448
4: P0445
5: P0075

I blew the tube going to the coolant tank. Replaced it and now I have a recurring Coolant visit workshop error. Check engine light is on. I can clear the codes and CEL will go out but will be on later. The car has no oil leaks with 81K miles. I have been on this site for a while, but just now reg. Anybody have any ideas on what this could be? I heard of oil wicking up wires and checked the comp under on the left side of engine and sure enough there is engine oil there. Where is the oil coming from? Will I need a whole new harness and computer? Is this even the problem? What will the cost be to fix?
Thanks for looking

The oil comes from the camshaft actuator. That's why the TSB told you to add the isolating wire.

I just got the car so didn't know about the TSB. Is the oil in the computer what causing the problem? Or are there other issues? I am going to fix this problem. Thanks

It might be the problem...you just have to pull the connector and check.

If that is the case and you got tons of codes like this, you will need a new wiring harness and a new ECU...both of them together is about half the price of your car.

It might be better for you to just get rid of the codes temporary and trade it in!

It leaks from that 2 circles.

Check the ECU connector(the green rectangle)

This is absolute gibberish. You have a major electrical corruption. Could be oil in harness or a damaged SAM. I'm not surprised the car goes into limp. Clean every wire & sensor & plug in sight & look for oil in harness from the cam sensors. Check for oil leak from transmission bush to TCU - TCU is under the passenger kickplate. Check ECU for oil as above.

I love your response, Glyn!

OK so now I know why the person sold the car. I have oil in all the above connectors plus o2 sensors. I have nothing in the transmission connector. I have seen on here that if you get rid of the oil leaking source and clean everything else up real good the problem will go away. With of coarse the constant checking and worrying of it coming back again!!! Where can I get the parts from, other than MB?

Isn't this a recall now? I'd ask the dealer about it because it can turn into an expensive fix.

twisted c230

I called MB and they said Dec. 4th of 2009 it is now a recall!! So Monday I will see how it goes. Thank you

Excellent news - Benz should pay - It's their screw up.

twisted c230

Got the car back they replaced both cam sensors and the whole wiring harness for no charge!!!! This car kicks a$$ now. Thanks all.

Glyn M Ruck

Good news - indeed!

For future reference, the campaign recall for the cam sensor (solenoid) / isolating wire is
