SLK55 AMG engine cover
Discussion
The little plastic pegs that clip into the rubber grommets holding on the front engine cover have snapped off. Three of them are missing, indicated in yellow on the attached picture. Some previous ham fisted idiot.
Does anybody have any bright ideas how to repair these. I have toyed with small screws with little covers covering screw heads. I could drill a small hole in the corresponding cover to join together. Or just leave alone ?
Mods please move to wherever suitable. I couldn’t decide which area to post in

The issue with araldite or similar is that it never really "grips" the original plastic and isn't likely to stay in place.
How are you with fabricating stuff?
What does the underside look like for rebuilding the pegs?
If it were mine, I would get a self-tapper into the original structure for some strength, then build up round it with body filler or superglue & plastic powder then get the shape with a dremmel & that should last.
Either that or take it somewhere that does plastic welding.

I'll second that but also suggestHow are you with fabricating stuff?

Chemical metal, like body filler but stronger.
GRP Paste, Plastic Padding do one, has glass fibre content for strength.
It is SERIOUSLY good used like this.
Drop superglue where you want to build up, pour on plastic powder, repeat until you have built up enough to work with & then use dremmel etc to shape what you want.
I have done several repairs/mods to plastic items like this & it is ridiculously strong.
I started with the kits that you can buy but you don't get much powder & it works out fairly expensive to do more than a little repair.
Now I do it 1 of 2 ways using High Viscosity Superglue (normal works virtually as well) and either plastic "filings" or buy a bag of plastic powder.
The way it works is the long molecule strings in the glue "fill in" the gaps between the plastic & the powder & all hold onto each other which makes it VERY strong.
It can also be used in the same manner with aluminium filings/powder & superglue on metal.

Ebay, just a couple of £ for a few 100g bag or get out a grinder/dremmel & a bit of scrap plastic & catch the bits, works just as well.
Something like this is fine.

It is meant to have heated metal dropped into it to "plastic powder coat" it, but for using it like I suggest it is really just a filler for the glue strings to hold onto/wrap round to increase the strength of the bond.
