BMW X2 Warning Lights & Locked Error Memory, Help Needed

Hi there! I have some experience with BMWs, and I faced a very similar issue with my 2020 BMW X1 last summer. Those warning lights can be quite scary when they all pop up at once! I own both the X1 and a BMW 2 Series, and when this happened to me, I was pretty worried too. The symptoms were almost identical, multiple warnings and a locked fault memory. Turned out it was an undervoltage problem caused by a failing battery controller. My trusted mechanic diagnosed it, and the fix cost me about 240 Euro including the new part and labor. Could you share more details about when these warnings started appearing? Like, did it happen after the car sat unused for a while, or while driving? Also, are you experiencing any starting issues? This info would help me confirm if it's the same problem I dealt with. Feel free to ask any specifics about my repair experience, happy to help!

Thanks for sharing your experience! I'm dealing with this issue at 124089 KM right after my latest service. The warnings started popping up while I was driving on the highway, totally out of nowhere. No starting issues so far, but it's making me nervous. Really hoping it's just the battery controller like in your case, as that sounds like a manageable fix. Did your mechanic need any special diagnostic tools for the BMW system? I'm trying to figure out whether to take it to the dealer or my regular shop.

Hey again! Thanks for those extra details about your X2. Interesting that it happened right after service, that's actually pretty different from my X1's situation. When my issue occurred, I was at around 98000 KM, and it wasn't connected to any recent service work. For the diagnostic part, yes, my regular mechanic needed specific BMW diagnostic tools to properly read and reset the fault memory. Initially, I went to him because I trusted his work on my other cars, but he actually had to collaborate with a BMW specialist to get the right diagnostic access. The BMW system is quite particular about these things, I learned! Just so you know, since my repair, I haven't had any recurring issues with the warning lights or fault memory. But given that yours started right after service, I'd actually suggest going back to where you had the service done. There might be a connection there that's worth investigating, which wasn't the case in my situation. One thing I learned from my experience, these electronic gremlins in modern BMWs can be tricky, and sometimes what seems similar on the surface can have different root causes. I'm hoping yours is something simple, but definitely get it checked soon before it potentially develops into something bigger. Keep us posted on what you find out, I'm really curious if it turns out to be something different from what I experienced!

Thanks for the detailed follow-up! You've convinced me to head back to the service center first, since the timing of these warnings is too coincidental. It's reassuring to hear you haven't had any issues since your repair. I've just scheduled an appointment for tomorrow morning, really can't risk having more problems pop up during my daily commute. I'll definitely let you know what they find out. Hopefully, it's something as straightforward as your battery controller issue, though I'm prepared for it to be something else given the service timing. Really appreciate you taking the time to share your experience and advice about the diagnostic tools too, that's super helpful info to have!
