BMW X2 Electrical Nightmare: Multiple System Failures

Hey there! I've got some experience with car maintenance and had a similar issue with my 2017 BMW X1 (I also own an X3). Those symptoms sound exactly like what I dealt with, unusual error messages, system failures, and weak starts. Turned out my battery was severely discharged and on its last legs. Had it checked at my regular workshop, and their diagnostic showed the battery was only holding about 30% of its original capacity. Got it replaced and all those electrical gremlins disappeared instantly. The whole thing cost me around 290 Euro, but it was worth every penny since all systems went back to normal. Before I share more specifics, could you tell me how many miles/kilometers you've got on your X2, and whether you've had any previous battery issues? Also, have you noticed if the problems get worse after short trips or when using lots of electrical accessories?

Thanks for sharing your experience! My X2 has 126586 KM on it and just had its regular service last month. I haven't had any battery issues before, but lately, I've noticed the problems get worse after short drives, especially when using the AC and infotainment system together. It's reassuring to hear your similar situation was fixed with a battery replacement. The weird thing is, my battery performance test during the last service showed it was still decent. Did your diagnostic initially show any signs before the battery completely degraded, or did it happen suddenly? Just trying to understand if I might be dealing with something different here.

Hey again! Thanks for those extra details about your X2. You know, that's really interesting because my situation was quite similar, my battery also tested "okay" during regular service about two months before everything went haywire. But here's the thing, I learned that these modern BMWs can be tricky because the battery can actually pass basic tests but still not be up to handling the car's complex electrical demands. In my case, it did seem to happen pretty suddenly, like within a couple of weeks, it went from seemingly fine to showing all those symptoms you're describing. What really caught my attention in your response is that you're seeing issues after short drives and when using multiple electrical systems. That's exactly what happened with mine, it would act up especially when I was just popping out for quick errands. I'd definitely suggest getting a more thorough battery test done, specifically looking at the load capacity. When my shop did the advanced testing, that's when they found the real problem. These newer BMWs are super sensitive to battery performance because of all their sophisticated electronics. Have you noticed if the problems are less severe after a long drive? With my car, I found that longer trips would temporarily make things better because the battery had more time to charge up. But the issues would always come back, especially after those short trips you mentioned.

Thanks so much for that detailed explanation! What you're saying about the battery load capacity makes a lot of sense. Come to think of it, I have noticed the car runs better after longer drives, which totally fits with what you described. I guess the regular battery test might not be telling the whole story. I'll definitely get that advanced battery testing done, seems like these modern BMWs need more thorough diagnostics than just the basic checks. You've really helped me understand what might be going on here. I'm feeling much more confident about getting this sorted now, especially knowing someone else had such similar symptoms that were fixed with a proper battery replacement. I'll make an appointment with my mechanic tomorrow for that detailed battery check. Who knew these fancy electrical systems could be so picky about battery performance! Thanks again for sharing your experience, it's been super helpful!
