Eseries radar sensor error

Greetings. The symptoms you describe are indeed indicative of a potential radar sensor malfunction. Several systems rely on the data provided by this sensor, hence the cascading failures you're experiencing. Considering the age of your vehicle and the accumulated mileage, it would be prudent to ascertain whether the sensor itself is obstructed or damaged. Have you inspected the sensor's physical condition and cleanliness?

Thanks for the quick reply! Where exactly is the radar sensor located on the Eseries? And is it something I can clean myself, or am I risking making things worse?

The radar sensor's location can vary depending on the specific configuration of your Eseries, though it is typically situated within the front bumper or grille assembly. While cleaning the sensor may resolve the issue if it is merely contaminated with debris, I must caution that improper handling could exacerbate the problem. Given the sensor's critical role in various safety systems, it may be advisable to consult with a qualified technician to ensure correct diagnosis and rectification.

Thanks for the advice! Turns out the sensor was just dirty. Cleaned it and the errors are gone. Cost me 45€ for the cleaning at the workshop. Appreciate the help!
