CEL on '03 C230k coupe need help with solving issue
I was hoping someone could help me out on a problem I'm having. I have '03 C230k coupe w/75,000 miles on it. Have a check engine light issue I cannot get solved. There has been no change in the behavior of the car since the light came on. Took it to local shop and the shop said they were getting codes P201c/P2038/P2058 on the way to shop stopped @ Autozone, their scanner said code P0172. Shop changed out downstream O2 sensor, but did not fix problem. They finally gave up on trying to figure out problem and refunded my money. Hoping that one of you out here may have had this issue to help shed some light on it. Any input would be great, thanks in advance for any help

Check your cam sensors first:

Same problem I had. Leaking cam sensors fouled the wiring harness.
Not a good situation. Get it checked out ASAP, maybe you can save the ECUs.
