EQC Radar sensor issue resolved

I can offer some insights I have a similar EQC and experienced comparable symptoms The error message, the compromised safety systems, it all sounds familiar First, has the vehicle been exposed to inclement weather recently? Check the radar sensor itself, often located behind the front bumper Road grime, salt, or even a build-up of insects can obstruct the sensor's field of view This can trigger a sensor malfunction, especially affecting systems like adaptive cruise control Are you able to determine the specific error code stored in the memory? A diagnostic tool can provide more granular information, potentially pointing to the exact sensor affected or even indicating a communication issue within the system Knowing this information will help determine the next steps

Thank you for the swift and insightful response I appreciate the suggestion to check the sensor for obstructions I will certainly inspect it for any visual contaminants Regarding the error code, is there a specific diagnostic tool you would recommend for retrieving this information? Also, could a simple cleaning potentially resolve the electronic issue, or is a more involved repair typically required?

While I cannot recommend a specific tool, any OBD II scanner capable of reading manufacturer-specific codes should suffice Regarding cleaning, yes, a simple cleaning can sometimes resolve the issue, especially if the sensor is merely dirty However, depending on the nature of the error code, it may indicate a deeper problem: a faulty sensor, damaged wiring, or even a software glitch within the driving assistance system's control module If cleaning does not resolve the issue, and given the potential impact on safety systems, I would advise consulting with a qualified Mercedes-Benz technician They possess specialized diagnostic equipment and expertise to accurately pinpoint the cause of the sensor malfunction and perform the necessary repairs In my case, cleaning did not solve it, and a visit to the workshop was necessary They recalibrated the sensor after cleaning it and the safety systems returned to normal

I am most grateful for your comprehensive guidance Following your advice, I had the sensor cleaned and recalibrated at a qualified workshop The error has indeed been resolved, and the safety systems are now functioning correctly The final repair cost was 45€ Your shared experience and recommendations were invaluable in resolving this sensor malfunction Thank you again for your assistance
