Unknow Torx found on carpet F33 430D

naunos · 02-16-2025, 08:28 AM

Hello to all,

I found a Torx screw mounted with a bearing on it .

It was under the passenger seat on my f33 430d

The screw is worn out on its thread .

I can’t found where it is coming from seat or maybe convertible roof ?

Or maybe a lost screw which was already replaced ?

Here are some pictures attached.

Thank you for your help !

I doubt if it's there's only one, so finding another one that hasn't fallen out would be the way to identify it.

It does look like one of these already installed:

Which is very similar to screw in E92 seats, but that one uses a plastic spacer:

Thank you for your reply, indeed it looks like it, but still can’t find its place 😓
Still looking for its place

Interesting how it is partially painted as well. Is there something that matches the color under there?

Are you taking the seats out just to clean under them? I have to take mine out to try to freshen up the seat belt retractor, it's not working very effectively.

Highly likely it is a some kind of anti-galling coating on that machine screw head.
