A start on this can be made looking through this:-

And the owner manual where you’ll find things like holding the unlock button on the remote opens the windows, holding the lock button down closes the windows. A double press on the lock button deadlocks the doors.

Watch this:-

 

Test release button on the inside of the tailgate lock in case it won't open
Test string in boot to pull open the fuel filler flap in case it won't open.
Don't panic about all the errors when the battery is dis/reconnected. They will disappear.
If the turbo gauge is not there in D mode, then turn off radio_repetition setting in menu.
Turn off the DRLs in the menu to preserve the LEDs so you don't get an MOT failure for broken sidelights.
Respect the interior door handles!
Boot has a second 12v cigarette lighter socket.

 

Congrats. Post some pics...👍

Can't help too much with your motor...we have a petrol...

All I'll say is, you'll love it and it will put a smile on your face every time you get in. Not to mention the looks and comments from complete strangers...😉
