BMW X1 Radar Sensor Issues Causing Multiple Warning Lights

Hey there! I had a similar issue with my 2014 BMW X3 last year (I'd say I have some experience working on BMWs, as I also owned a 3 Series before). Those error messages can be pretty annoying! In my case, the radar sensor was just really dirty and needed a good cleaning. Took it to my regular workshop, and they diagnosed it pretty quickly. The whole thing cost me about 45 Euro to get sorted out. The symptoms were exactly like yours, multiple warning lights and system errors popping up on the dash. Could you share what specific error messages you're getting on your X1? Also, have you noticed if this happens more in certain weather conditions? This info would help me understand if you're dealing with the same problem I had.

Thanks for sharing your experience! I actually have only 7198 KM on my X1 since my latest service, so I'm a bit worried about these errors showing up so soon. The warnings seem pretty unusual, they pop up regardless of the weather. Getting stuff like "Driver Assistance System Limited" and "Front Collision Warning Deactivated." Super frustrating when you're driving and these keep flashing. Did your mechanic mention anything about sensor calibration? I'm wondering if I should just get it cleaned first before going for any major repairs. By the way, did you need to get any recalibration done after the cleaning?

Hey again! Yeah, I totally get your concern about those errors showing up with such low mileage since your last service. That would worry me too. When I had my X3 fixed, the mechanic actually mentioned that sensor calibration can be necessary sometimes, but in my case, it wasn't needed after the cleaning. Just a thorough cleaning did the trick. Those exact same warnings you're getting, "Driver Assistance System Limited" and "Front Collision Warning Deactivated", were what I saw on my dash too. But here's the thing, since your car has such low mileage since the last service, I'm wondering if there might be something else going on. Mine was actually pretty grimy when it started acting up, but with only 7198 KM on yours, dirt buildup seems less likely. Have you checked if there's any visible damage to the front sensor area? Sometimes even small impacts we don't notice can mess with these systems. When my 's X1 had similar issues, turned out a small parking bump had knocked the sensor slightly out of alignment. I'd suggest starting with a visual inspection and maybe a gentle cleaning, but given the low mileage, might be worth having the dealer take a look. Could be covered under warranty if there's an actual sensor issue.

Thanks for all that detailed info, super helpful to hear about your experience! Makes sense about the calibration potentially not being needed if it's just a cleaning issue. I took a closer look at the front sensor area like you suggested, and honestly, everything looks pretty clean and undamaged. No visible signs of any impacts or dirt buildup, which I guess makes sense given the low mileage. That's what's making me more concerned, feels like there might be something else going on here. Think I'll take your advice and head to the dealer to get it checked out. Since the car's still fairly new with such low mileage, might as well have them take a proper look. Better safe than sorry, especially with these safety systems acting up. Really appreciate you sharing your experience, helped me figure out my next steps!
