Thanks so much for sharing your experience! Glad to hear it was just the backup battery, that's exactly what I was suspecting with mine. Hey, do you remember roughly how much you ended up paying for the fix? Also, has everything been working smoothly since the replacement, or did you notice any other quirks?
Hey again! Yes, absolutely, happy to share the update! After getting it fixed, the emergency call system has been working perfectly, no more error codes or any other issues. I paid 110 € for the whole thing, which included the new backup battery and labor. Honestly, it was worth every penny for the peace of mind. The funny thing is, once they replaced that emergency battery, all those annoying warning messages disappeared instantly. It's been about a month now, and my iX3 hasn't shown a single error since. The system runs all its checks normally, and everything's back to how it should be. Just make sure they do a full system check after the replacement, mine did, and I think that's why it's been running so smoothly. If you're still unsure about your mechanic, maybe this is a good chance to try someone new? It's a pretty straightforward fix for anyone who knows BMWs. Let me know how it goes when you get it sorted!
Thanks for all the detailed info! Actually, I bit the bullet and took it to a different mechanic yesterday. You were spot on, it was the backup battery! Funny story though, when I got there, the mechanic immediately knew what was wrong just by looking at the error codes. He had this "seen it a million times" look on his face. Turns out the fix was even cheaper than what you paid, and the whole thing only took about 45 minutes. The best part? While I was waiting, the mechanic showed me where the backup battery is located and explained how the whole system works. Way better experience than my last mechanic who always kept me in the dark. System's working perfectly now, and those annoying warning lights are finally gone. Really appreciate everyone's help on this. Think I've found my new go-to mechanic too, what a bonus!
Hey there! I actually faced a similar issue with my 2021 BMW iX3 last month. The emergency call system started throwing error codes, and yes, it turned out to be the backup battery. The emergency battery is separate from the main one and needs replacement when it dies, it's a safety feature that keeps the emergency call system working even if the main battery fails. Had it checked at the service center, and they confirmed the backup battery was completely drained. It wasn't a major repair, but it's definitely something you shouldn't ignore since it's a critical safety feature. The replacement took about an hour, and they also ran a full diagnostic to ensure no other systems were affected. Based on your mileage and the symptoms you described, it sounds exactly like what I experienced. You'll need a proper diagnostic test to confirm, but I'd bet it's the emergency battery. Just make sure whoever handles it uses the right battery spec for your i5. Hope this helps!
