i'm at work so forgive the lack of pictures mate.
1. Use a alan key to remove the silver bit of your interior door handle, there is a hole in the back side of the handle that you should be able to fit somthing into to pop the panel off.
2. once off, remove all of the screws i think there's above 8 in total.
3. remove the electric windows panel and diconnect from wires (this should just slide out), as well as the door handle.
4. You then need a flat head screwdriver and wrap some maskingtape or somthing to protect it, and use this to gently prize the plastic from the door matel, there are 2 gaps at the botom of the door and this is a good place to start, this does require some force but try not to be to harsh so you dont ruin your door

if memorie serves there are about 5 "plugs" you need release from the door so it is released.
5. when the door panel is loose then lift it up and pull away from the door and it should come out pritty easily.
There's a pritty good guide on the type R forum that i used.
Everyone feel free to add bits i may have forgot.

This should help a little
