BMW i3 Multiple Issues: Fuel Sensor & Stalling Problems

Hey there! I've got some experience with hybrid cars and had a pretty similar situation with my 2016 BMW i8. I understand your frustration! I had almost identical symptoms, stuck fuel gauge and engine issues. After checking with my regular workshop, it turned out to be a blown fuse connected to the fuel pump circuit. Total repair was 52 Euro for parts and labor, pretty straightforward fix, honestly. Before jumping to conclusions though, what's the exact error code you got? Also, how long has this been happening? With these BMW hybrids, sometimes symptoms can point to different issues depending on the model and specific system. I'm curious about your car's mileage and service history too, might help pinpoint the problem. Let me know these details and I can share more specific advice from my experience.

Thanks for sharing your experience! My i3 has only done 8585 KM since my latest service, so this issue caught me off guard. The error code I'm getting is P0462, and these problems started about a week ago. The stalling is what worries me most, it happens pretty out of nowhere even when the battery is well charged. Your fuel pump circuit suggestion sounds promising since it might explain both the gauge and stalling issues. Did your car also stall before you got it fixed? Really hoping it's just a fuse like in your case. The thought of a major repair bill is giving me sleepless nights!

Hey again! Yes, my i8 definitely had those unusual stalling issues too before I got it fixed, super annoying and honestly a bit scary when it happened in traffic! Seeing that P0462 code on your i3 brings back memories, as it's exactly what I dealt with. With only 8585 KM since your last service, I'd be frustrated too. The good news is, when I had this issue, the stalling completely stopped after the fuse replacement. The symptoms match up perfectly, my car would stall even with a good battery charge, just like yours. Quick tip from my experience, while you're waiting to get it checked, try to keep your tank at least half full since the gauge isn't reliable. That's what I did to stay on the safe side. You're right to hope for a simple fuse fix, that's honestly the most likely scenario based on the symptoms. Mine was back to perfect after the repair, and I haven't had any similar issues in the two years since. Let me know how it goes after you get it checked out. Always happy to share more details about my experience if you need them!

Thanks so much for all this detailed info! It's really reassuring to hear your i8 had such a straightforward fix for the same symptoms. I've actually booked an appointment with my mechanic for tomorrow morning, and I'll definitely mention the fuel pump circuit fuse to them. Following your advice about keeping the tank half full, filled it up today just to be safe. You're right, it was a bit nerve-wracking driving with an unreliable gauge, but at least I know I won't run dry now! Really appreciate you taking the time to share your experience, especially about the long-term success of the repair. The fact that you haven't had any issues for two years after the fix gives me hope. I'll definitely update you once I get the diagnosis. Fingers crossed it's just that pesky fuse!
