im not sure if plastic welding will work on that material,you could try the technique out on a less visable area .Plastic welding involves using a mesh and under heat (soldering iron) melting it into the surface ,then using a flexy filler flatten it back and paint ,you will most likely see evidence afterwards ,if you can get the the end of the crack ,drill a small hole to stop it spreading

ideally support behind with fibreglass mesh and then plastic weld and fill. you can buy kits with a soldering iron with adjustable heat and various plastic rods to melt into the joint. then grind back with a dremel and paint if neccessary to conceal

I have had very good results with Plastex HERE plenty of info on website to show you how to use it but it's very easy.

Thanks all for your advice, much appreciated. I can´t get behind the panel, so I´ll try the plastic weld method then paint to conceal.

I used to do plastic welding as part of my business ,not all plastics lend themselves to the technique , use 400 grade sandpaper to flatten down the filler ,have a block behind it ,then some highbuild primer and flatten back with 1500 ,mask everything that you dont want painted and key all areas.

Just had a thought ,i fixed a brand new moho bumper many moons ago ,i welded the bumper,then used filler and gell coat repair (get it from a marine shop) the problem with the gell coat is that it will look brand new so a bit of primer and paint over it faded out the difference

After the repair you could always use some vinyl cut to shape to cover up the repair.

Use a different colour maybe and it will look like it is supposed to be there
