Removing the rear wiper arm was impossible....i tried pulling hard, levering it off, I even resorted to a rubber mallet......in the end I found that when the motor is undone then you can move it enough to get in to the last nut to get it off......
AND the boot door liner.....what a nightmare.....fingers were red raw and those metal clips don't like coming out
But I got it done......my estimated 20 minute job took an hour
Flipping DV was easier to change.
