Smile Fasteners used in W211

Hi everyone,
Do you know the name or part number of these fasteners used in the engine bay of a 2005 Mercedes W211? They secure two small plastic covers near the windshield. One of those covers protects the engine bay fuse box from above. It looks like my car is missing 3 out of 5, and I’d like to buy replacements. I assume these are common fasteners used on many Mercedes models.
Thanks in advance!

That looks similar to the ones I replaced in my W204. Theres one holding the top of the front wheel well liners and also one in the engine bay at the grill bracket. Expensive for what they are. May find generics on eBay or aliexpress cheaper if you need alot.

The dealer helped me find the number of this part and I managed to buy it.
It is:

A 002 988 0542
A0029880542
0029880542

It looks like this part is used in many different Mercedes models.
Apparently, they are used not only with the equipment in the engine compartment, but also at the wheel arches, the cowl panel, and the underbody shields.
The original ones cost about 4 EUR, while on the internet you can find replacements for around 0.3 EUR.
