How to hold the panel in place after 20 year old glue failes to do so?

I am not a mechanical engineer but something can be pulled off i think by using screws.

Any ideas how to tighten up the door panel to stand in place when you put your arm on the arm-rest bit? Can i do it with screws, drill holes in the panel so screws can go trough instead of glue?

Or there are purchasable parts that can replace the plastic bits that hold it?

Yeah, it happens to every Lupo... Even worse is when the moulded clips break, then the only solution is to glue the retaining clips.

And their position is important when you glue them back on. I use polyurethane rubber adhesive.

They break when you lean on that ledge that the electric window switches are mounted on.

I've had an idea how to prevent it happening, by mounting a strip of something on the top of the door so that the door card panel hooks over it, like on Golfs. I haven't tried it yet. I broke one of my door cards (again...) a couple of weeks back.

Cheap design. 

Haven't tried it yet. I don't know how they are called, circular metal plates that go with screws. If I put screws with flat end, one metal plate on one end and another plate on the other end and then tighten the panel with mutter (how are these called) it could possibly work.

Just not sure how strong the panel's material is if it breaks after some time.

A combination of these three

The more screws the stronger it will be. Problem is if I could reach all holes in the metal to put a screw and if I drill a hole in the right place of the panel so its even. Not too high, not to low, not too left, not too right :) 

But door has already two screws, for the door holder plastic so...

Bolt, nut and washer are the words you're looking for :). A "screw" has a pointy sharp end to pierce and make its own hole.

That might be an idea. Do you mean where the retaining clips push into the door holes, you put bolts. Then you fit a washer and nut (with a small amount of glue)? We need some pics...👍🏻

Something like that, yes. Maybe skip glue all together. Washer on the indoor side and then washer in the outer side of the metal with a nut. And then another combination for the outer side of the cardboard panel with washer and a nut. Tight those properly to hold. 

Well, there could be various lengths of the bolts to reach the outward parts of the panel. The hard bit is the reach all the holes by hand. And then how to drill holes in the panel to not shift sideways... :) 

Maybe even use rubber washers, rubber on one side.

Still work to do but putting screws to hold the plastic frame on the top works

Used glue but it didn't stick at some points

But screws and glue together could work

I would go fully custome and drill small holes in door metal, then line wood bolts thru door cards into the drilled holes. With 8 bolts it would hold better than original. 

There are many other options how to hold that door card in place way better than original, like using threaded river nuts, in my opinion, repairing stock mounts is the worst way to solve this problem.

Hmm just searched threaded rivet nut. Didn't know such thing existed. 

But how to you mount it in the existing holes in the door metal?

You just screw it once and once inside when pulled in opposite direction it will deform in such a way that it will stick strong?

No it is not that simple to install any rivet, you need to use rivet tool, or pull it with diy tool, watch some videos on youtube and you will get it.

Actually there was a third place where a bolt can be mounted along with a washer and nut. Just below one of the holes diagonally. Somehow i got the math right and drilled hole in the cardboard at the right place. So a long fat bolt, a nut and a washer and now the cardboard holds on three screws (two at the door holder handle) and it seems strong and not moving.

I think it was a triangle of 1.5 cm, 2.1 cm and 1.5 cm if you look at one of the holes. This is how to get where the big hole is and to drill a hole in the cardboard.

Haven't made a picture of the final set-up but this hole is here.

But yes, rivets and plastic bolts like these can be used as well if you can find them

The problem that appeared, if you put one of these in the holes, cannot remove them without cutting them in half because different size than the original ones. Plus it broke one of the plastic holders. So i skipped these for now.

This means if you use these plastic bits you will not be able to remove the cardboard from the door without breaking the plastic holders on the inside.
