Heres my finished article. Two M6 screw bolt on the rear, there are 4 little screws to undo. Once undone you can thread the bolts through the rear mount. Then mark your hole positions on the dash just above the cupholder and drill using a 6mm drill bit. Wood or metal will be fine as it's thick plastic. Then screw the backplate onto the cup holders and push into the holes and nut up the bolts. You will need to remove the trim where the radio is but put the car in N, and the panel lifts up, carefully as you need to undo 5 wiring connectors. Then you've got a fully new cup setup.

After extensive looking (i.e. camera, pipe cam and pulling trims etc off). I found that you need to remove the whole centre console lower dashboard to get those screws. So i've decided to make my own from the Amazon standard vent cup holders. I bought these CupHolders , Next I remove the air vent clips, put a 4mm drill bit through the retaining back plate and then through the old cup holder cover/pull arm. feed some 4mm threaded screws through (like faceplate screws) then bolt them on. No more brittle plastic and doesn't cost me over £60. Will post pictures onec I've done it.

Thanks! I'm going to tackle fixing my power sliding door next. I actually managed to successfully fix and wire the rear power boot before this, so I'm ready for the next challenge

Thank you

Thanks Gamith, I don’t think it is that part but will use the diagram to try and identify it. It looks like it slots in the top and just runs the width of the van bending round at each end.

Thanks Charlie, I’m familiar with that product, will check it out and see if they have one in black.
