BMW i8 Won't Start: Locked Steering and Access System Errors

Hey there! I had a similar issue with my 2016 BMW i3 Hybrid last year. The symptoms you're describing match exactly what I experienced, locked steering, multiple error messages, and access system problems. The root cause in my case was a defective door handle sensor unit. These units contain electronic components that communicate with the car's central locking and security systems. When they fail, the car can't properly verify the key presence, leading to those start-up and steering lock issues you mentioned. Got it fixed at a certified shop specializing in BMW electronics. It wasn't a quick fix, they had to order specific parts and reprogram the system, but it wasn't a major mechanical issue. The car's been running perfectly since then with no recurring problems. If you're getting error codes related to the access system, I'd strongly suggest going directly to a shop that specializes in BMW electronics rather than a general mechanic. This kind of issue needs proper diagnostic tools and expertise with BMW's systems. Best of luck with the repair.

Thanks for sharing your experience! This is really helpful since it sounds exactly like my issue. Good to hear it wasn't anything too serious. Would you mind telling me how much the repair ended up costing you? Also curious if you've had any other electronic gremlins pop up since they fixed it? My other concern is how long the car was in the shop, hoping it won't take too long since I need my car for work.

Hey again! Happy to give you an update! I recently got my i3 fixed for the exact same issue you're dealing with. The total bill came to 480 € for replacing the faulty door handle electronics. Money well spent, I'd say, as the car access system has been working flawlessly since the repair. My car was in the shop for about two days, they had the parts in stock, fortunately. No other electronic issues have popped up since then, and it's been about 6 months now. The car starts perfectly every time, no more error messages, and the steering lock works as it should. I totally get your concern about needing the car for work. I was worried about that too, but the electronics specialist shop I went to really understood the urgency and got it sorted quickly. I know it might seem like a steep price, but considering how complex these systems are, and more importantly, how reliably it's been working since, I think it was worth every penny. These BMW electronics can be tricky, but once they're properly fixed, they tend to stay fixed! Let me know if you need any other info!

Thanks so much for all the details! I actually just got back from the mechanic today and wanted to update you. Turns out it was indeed the door handle sensor unit, just like you mentioned. The repair took three days total since they had to order the part, but honestly, it wasn't as bad as I feared. My final bill came to a bit more than yours, around 550 €, but the car's running perfectly now. The mechanic also did a thorough check of all the other electronic systems while they had it, which gave me some peace of mind. No more error messages, the steering wheel unlocks smoothly, and the start-up is flawless. Funny thing is, during the repair they found a small wiring issue that could've caused problems down the line, so they fixed that too at no extra charge. Really glad I took your advice about going to a specialist rather than a general mechanic. They clearly knew their stuff with BMWs. Thanks again for sharing your experience, it really helped me make the right decision!
