a better fix would be to just pull the fuse out. thats what i did with mine. i would love to have the handover working again but it would cost about 50 pounds to get one from a scrapyard and seeing this i kinda don't want to spend the money on it as this is the third different issue i have seen with them . mine pushed the seatbelt forward too fast and the seatbelt got locked and something in the arm's end broke / snapped and ever since it just doesnt grab it anymore

Yeah but its really hard to reach the seatbelt from the front imo..

Hey I'm not sure where to find it but didn't someone post a part that attaches to the headrest so that the "belt butler" could be disabled and you could just have it hooked to the headrest ? It would be a PITA for rear passenger but how many times do I have rear passengers? No often. Anyway, if I find it I will repost the link.

Could you see if you could do a repair on it or add a replacement metal tab?

I think its hard to repair because its thin cheap plastic (german engineer).
The only thing we can do is go to our dealers and ask if they can give us a replacement plastic.
Keep us updated

mine does stick out it just never grabs the seat belt... i dont kno why... any clues?

Here you go

OP, how did you take out that arm?

Does anyone know what part number that is? Mine seems to be broken :/

I carefully pull it out, it wont break just make sure the door is closed and the motor of the arm is not running (when you hear nothing)

I noticed this when it happened to both the driver's and passenger's side on my car (within 3 weeks of one another). I contacted BMW since, like you, I knew that I did not need the entire assembly. I sent lots of pictures and explained the engineering flaws in the design. I do not remember the name of the guy I spoke to, but we exchanged approx 3 emails over the course of 2 weeks. Unfortunately, he told me that the part I requested (that thin piece of plastic) is not available separately. I'm not sure how much effort he really put in, but I think the best option is to try to obtain it at a scrap yard because I'm not spending $300-$400 for new assemblies when they're not needed.

Yeah and thats BMW service...! I think the scrap yard is the best choice
