i dont think there is one, but its DEAD easy
open the boot and look at the inside of the hatch, theres two torx screws in the handles, unscrew them
the plastic casing is now only held on by plastic clips which run all along the edge of it, thier easy but delicate to unclip so be careful (should be around 6-8 of them?)
once the casings off you'll be looking at the wiping arm motor, its secured by three screws (possibly torx screws again, cant exactly remember), unscrew them
then look for the white plastic tube which is connected to it, thats the tube for the washer fluid,. it's tricky to get off the motor,, so i just cut it off
this tube needs to be folded on itself, cable tied, taped,, do whatever you've gotta do to it to stop any chance of fluid coming out if you accidently press the rear washer fluid button
after the 3 screws and washer tube is free of the motor you now need to be looking at the outside of the hatch
Simply pull the plastic cover off the wiper arm where it meets the hatch body and it'll reveal a large bolt,
unscrew that, the wiper arm will come off and the motor is totally free of the hatch!!
now you've got a hole in the screen which can be covered up by a grommet purchased from halfords for about 50p, i think its a 25mm grommet but dont quote me!
to ensure the grommet is water tight run a layer of silicone sealant around the edge on the inside,
re-attach the plastic casing on the inside and your sorted!!!
its probably quite hard to understand all this without pictures, i'll have a search now to see if i can find any for you
hope this helps
