This is basically all you need to know to remove the drivers door panel on an MPS6.

This shows the location of the three screws.

Screw B

Remove the lens by placing a small screwdriver into the recess at the back of the lens and it slides out horizontally.

.
Once this is done just pull on the trim to release the clips - just like any other vehicle.
Once the clips are undone lift the trim up to unclip from the top of the door, you have to then reach in to un-plug the three cables.
I found it easier when it came to reinstalling the panel to remove the switch panel making it far easier to get the plugs back in.
Hope this works - haven't uploaded for ages and I hope it helps.
