The code on 16:9 screen ikPxs fox ji :'(or engine immobiliser - leave it alone unless you have need and of course the correct code!
The V50 hopefully doesn't need a code if not locked
For deleting numbers on the dash I would initially empty phone memory and sim memory other than one number - for example "Home"
Go into directory on the car in telephone options turn radio tune knob until you see numbers you want rid of press and turn until C is selected then keep pressed until number disappears completely.
Sorry but mine is disconnected in the boot so typing this using my old BMW telephone operational manual
Oh and it doesn't have default PIN numbers typed in it.
Sorry I can't help more
