Hi, I have a W204 2008 c180 and the “auto lights inoperative” error comes up.

I have changed to new rain-light sensors as many old forums and youtube videos have recommended I do, but the error still comes out. Sometimes, the rain sensor still works, so at this point I’m not sure if it’s a connection issue (or what I’m not sure too) or a software issue.

Any advise?

    Updates: No coding/programming has been done pre or post change, and I changed the sensor from code A204 870 88 26 To A204 901 45 04

    have you checked the wiring harness for any damage or loose connections? sometimes the issue can be with the wiring rather than the actual sensors. also, have you tried resetting the error code after replacing the rain-light sensors? it could be a software glitch that needs to be cleared.
