arm that hands seat belt in coupe

Hey guys,

I have an odd issue with the little arm that comes out to hand you the seat belt in my 07' 335i coupe. The passenger side always seems to work, but the driver side seems to not retract fully every 1 out of 5 times (estimate). I noticed that you can actually pull the arm out further, which seems to be the issue, as it seems to pull itself out a bit further than it should (by itself, and I have to push it back in manually), and does not retract back into the slot.

Hope this makes sense and someone has encountered this so I don't sound like a crazy person. Any easy fix for this?

Thanks!

It's just crap- the damn thing never worked right in my E92.
I had gotten it replaced three times and still wouldn't work. I'm sure others can attest to how crappy they really are.

You can start with trying to get it replaced by the dealer if still under warranty, otherwise I would just pull the fuse on the damn thing and get the belt myself.

I should really search first, just saw the large "DIY" thread in here with the seat belt holder. I think I'm going to go that route and pull the fuse for it.

Can't find the right part number for mine though, I'm not sure which one it would be under these: http://www.getbmwparts.com/parts/200...335I/index.cfm

believe it's this?

I got the driver side replaced under warranty (I insisted upon a replacement, BMW instructed the dealers never to replace, just update the software), so it still works today, in year 6+. The passenger side kept getting stuck, and I got so mad I ripped it right out of its socket.

When I looked the parts up online, they were so expensive, I put the arm back in the socket, so that too now works about 75% of the time.

It was a bad design, so imho no use fixing it. You can try to disassemble and reassemble and see if it helps, it may.

I have had both arms replaced (once) and seatbelts (replaced 4x each side). 2nd to last time they installed some kind of "fix" were they place a plastic piece on the track at the bottom where the belt travels to shorten how far they go back. They work for a few months then stop grabbing.

The problem is the seatbelt itself gets worn and stretched where the arms grab on overtime. You can either get it replaced under warranty and go back every <2 years or if you're out of warranty they may just replace them because it is a safely item.

It was a great idea...but didn't kill it like they assumed it would. My past e92 335 drivers side would work perfectly and the passenger would work 10% of the time.

Ya. I definetely pulled that fuse.
Just thought it was tacky.
But, like you said. You can pull it out farther?
Whenever mine got messed up it was because it came out a little to far.

Try pushing it back.
Not all the way back in but untill the parts are all snug.

Always worked for me.
Good luck

Mine did a similar thing to OP and I would just give it a "love tap" and it would suck it back into place.

However, just as many times, the damn belt slip right off the arm.

Passengers found it amusing- I found it frustrating.

Now that I have an E93 I don't have these problems anymore- I have a whole different set of problems

Absolute crap. I can't believe they're keeping this 'feature' on later year models. They need to redesign this flaw asap

What fuse is it for the Seat Belt arms??

I'm so tired of the seat belt slipping off half way thru the extension.

I am seeing that the seatbelt itself is the problem. On a lot of the coupes by me the seatbelt is saggy and hangs there so the arm isn't even close to it. Repalced the seatbelt on one and all is well.

It's a poorly engineered design (this is coming from an actual engineer). I thoroughly documented my observations and took numerous photos explaining the flaws in the chosen materials and the chosen dimensions of the arms and submitted it to a bmw rep. He originally told me he would look into obtaining the part that I highlighted as being the weak link in the system (which is a thin piece of plastic), so I wouldn't have to purchase two new assemblies at about $800 for the pair. To my disappointment he told me he couldn't obtain the part separately for me.

I had the fuse pulled for a while, but I hated seeing the error code for the arms everytime I scanned my car. So the OCD in me won over and I coded out the arms so I'll never see a code again due to the fuse being pulled.

I really liked this feature on this car, so it's unfortunate more thought didn't go into the design.

there's a trick that you can do to your seatbelt so it doesn't slip off the seatbelt butler. look it up in the DIY section.
