Mini One Radar Sensor Problems

This sounds like a classic sensor malfunction, especially given the array of error messages you're experiencing. Before you jump to conclusions about a serious electronic issue, have you checked the sensor itself for any visible dirt or obstructions? These automotive sensors can be quite sensitive, and even a thin layer of grime can cause sensor failure. Where is the sensor located on your model?

Thanks for your reply Where exactly should I look for the sensor Is it easy to access, or will I need special tools I am not super familiar with car electronics. I just hope I don't mess anything else up while trying to fix this

Given the symptoms, I still suspect a dirty sensor is the primary cause, particularly as you describe the vehicle's behavior. You can locate it behind the front bumper, usually near the grill. Although you will not need specific tools, you will need access to the sensor without damaging any components. Prior to deciding to replace it, and after checking for obstructions, I would suggest having the sensor inspected by a shop. This will allow them to confirm it is working correctly.

You were spot on I cleaned the sensor like you suggested, and it totally fixed the issue. Everything is working perfectly now. I am so relieved it didn't need any fancy radar calibration or a new expensive automotive sensor The whole thing cost me like 45€ to get the specific cleaner, which is a lot better than I thought it would be. Thanks again, you saved me a ton
