BMW iX2 Total Power Loss: Dead Dashboard & Systems Down

Hey there! I actually faced a similar issue with my 2021 BMW iX3 last month. The symptoms you're describing sound exactly like what happened to me, complete electrical shutdown and dark displays. In my case, it turned out to be a faulty main power distribution module connection. The high-voltage cable connectors had developed corrosion and weren't making proper contact. It was a serious issue that needed immediate attention since it affected the entire electrical system and could've damaged other components. The repair involved cleaning the connectors, replacing a few damaged terminals, and recalibrating the power distribution system. Main thing is to get it checked by someone who really knows electric BMWs, it's not your regular mechanical issue. If you're seeing FlexRay bus errors, it could definitely be related to the power distribution problem. Don't drive it until it's fixed, as these electrical issues can affect critical safety systems. Have it towed to avoid any risks. Hope this helps. Let me know if you need any other details about what to expect during the repair process.

Thanks for sharing your experience! That's really helpful since I'm dealing with pretty much the same symptoms right now. Quick question, do you remember roughly how much you ended up paying for the whole repair job? Also, has everything been running smoothly since they fixed it, or have you noticed any other electrical quirks? I'm trying to get a sense of what I'm in for, both cost-wise and whether I need to watch out for any follow-up issues with my iX2.

Hey again! Great to hear back from you. Just wanted to update you, I took your advice and had my iX3 checked out by a BMW specialist. Turns out it was indeed the FlexRay bus issue, just as we suspected. They found and fixed a faulty cable connection, which wasn't making proper contact. Pretty straightforward fix in the end, only cost me 95 € for the repair work. The best part? Everything's been running perfectly since then. No more electrical glitches, no dark displays, all systems are working just as they should. It's such a relief! You know how these electrical gremlins can be in modern cars, they can really drive you crazy. But once they found the root cause, it was sorted pretty quickly. My advice would be to get it checked sooner rather than later. These things can snowball if left unchecked, and you really don't want to end up with more expensive repairs down the line. If your symptoms are similar to what I had, hopefully you're looking at a similarly straightforward fix. Just make sure you get someone who knows their way around electric BMWs, it makes all the difference. Let me know how it goes with yours! Always happy to share more details about my experience if you need them.

Thanks for following up! I actually just got back from the mechanic today. What a relief, it's all sorted now! Like you said, finding someone who really knows their stuff made all the difference. I ended up going to this certified BMW specialist who spotted the issue straight away. Funny enough, while it looked scary with everything shutting down, the fix wasn't as complicated or expensive as I feared. They found a corroded connection in the main power distribution unit that was causing all the chaos. The repair cost me about 120 bucks for parts and labor, way less than I was bracing myself for! The mechanic did a great job explaining everything. They cleaned all the connections, replaced a couple of worn-out parts, and ran a full system diagnostic. The car's running like a dream now, all systems working perfectly, no warning lights, nothing. Such a weight off my shoulders! Really appreciate you sharing your experience, it helped me stay calm knowing someone else had dealt with the same thing successfully. These modern electric cars can be tricky, but at least when you find a good mechanic, they can sort things out pretty quickly!
