Mercedes SLC radar sensor problem

Experiencing an electronic issue with my 2017 Mercedes SLC gasoline engine with low mileage The radar sensor seems to have failed I'm getting an error message and the error memory is full Several driving assistance systems are defunct and a warning light is on Has anyone else encountered a similar radar calibration issue or general malfunction of collision avoidance features I'm thinking of checking if the sensor is dirty What are your thoughts

Summary of the thread

A 2017 Mercedes SLC owner is experiencing a radar sensor failure, leading to error messages and malfunctioning driving assistance systems like Distronic Plus and Active Brake Assist. The issue may be due to a dirty sensor, as cleaning it resolved a similar problem for another vehicle owner. The suggested solution is to clean the sensor and, if necessary, seek professional assistance to ensure proper calibration and functionality.

That sounds frustrating I had a similar sensor failure problem with my older Volvo some years ago, although my issue was impacting the adaptive cruise control I am unsure if it will help, but could you perhaps indicate which systems are failing

Could you elaborate a little more about which systems were affected in your Volvo I'm trying to ascertain if the issues are comparable In my SLC, it's primarily the Distronic Plus and Active Brake Assist that have ceased to function, along with associated warnings related to collision avoidance

I understand In my case it was the City Safety system that stopped working I would advise that you go to the workshop It cost me 45€ to fix

I appreciate the insight I suspected it might require professional attention I will book an appointment with the workshop to address the radar sensor issue and subsequent electronic issue As you suggested, it was in fact a dirty sensor Cleaning it solved the problem, for a total cost of 45€
