Hello all, I have a 2017 c43 and have searched for my specific issue with no luck. I have some sensor issues involving several didn’t warnings. I have added some pictures of the problems I am seeing. I have cleaned all sensors and windshield from all the troubleshooting steps I have found and nothing seems to work. I hope someone has seen this issue and can give me some steps to troubleshoot. As you can see from one of the pictures the turn signal in the front does stop working.
I've had the same issue on my 2018 C43 for a while now.. I get the blind spot assist and the active brake assist. Have you found the cause by any chance?
Sorry, I don't have any solid leads if it's permanently on, when the low beam warnings turn on, are they visibly not on? Wonder if it's a problem with the cameras at the top of the windshield? Maybe it has logic to look for more light when the low beams are on, can't detect that and assumes it's a headlight issue?
About once every 3 months while driving, I'll get the Brake Assist disabled warning and the cruise control and related systems will be disabled. It will clear about 10 minutes later. I had asked the dealer to check during one of my prior visits, and they didn't find anything concrete other than suggesting that sometimes environmental factors (fog/mist specifically) can sometimes throw off the sensors. The only time I've seen it legitimately disabled is in a heavy snowstorm and thick snow was caked over the radar sensor in the Mercedes badge at the nose.
