Anyone know what these fasteners are called/where to buy them?
 

See photo,
The fasteners that slide onto the car that the twists caps *circled in red* lock into? 2 of them are missing on my X5 and my entire cowl vent is only mounted by 2/4 of the twists, I’d like to replace the missing 2 and have my cowl vent secured as originally designed.

You can look them up on realoem.com and order them from ECSTuning or one of the other sponsors. You might have to troll around a bit to find them but I'd guess they are in the bodywork section. Very useful site for many things. 51711947419 They were in the heating and cooling section

Nr.14

That doesn't look like the correct part. I checked the part for an e46 and it only crosses over to the X3.
Tomorrow I can see if the actual part from my e46 fits the X5.

I've installed these parts to my own E53 just a while ago. They are correct.

I do not think the 1:4 turn clips are a separate part. I think somebody will make a 3d printed part to solve this problem.

I probably have 3 working clips between both mine and wife's X5. I may solve this problem soon.

You are correct - these ARE the correct part - I've also replaced them myself in the past.... They are called a plug-in nut (BMW 51711947419)

BUT... if Dinan4.6is is talking about the mating cam, the part on the cowl itself (and I think this is the case) then you're SOL looking for them as an E53 part - they are not available without buying the entire cowl (or scuttle as it is sometimes called - BMW call it the micro-filter cover).

However, as has been suggested, a similar part is used on other vehicles, namily the E83 X3...

Not 100% sure they fit/work but it's the closest we've found...

*edit* - re-reading the original post, I now think Dinan4.6is IS asking about the snap-in nuts.... :thumbup:

I hugely recommend you silicone this in place, or you will be looking for more again soon.

That's some helpful stuff. By accident you gave me a great idea how to solve the MUCH more common problem of the quarter twist "screw" breaking off.

I'm thinking of adapting mine to use actual screws and adapting this push in nut to take them maybe using a drywall anchor as the go between.

Second that. I used butyl adhesive tape (same as on vapour barriers).
