all zafiras run eobd2
the socket for it is right next to the handbrake
there is a kind of pocket there between the handbrake and gearstick
pull up the base of that pocket with something pointy like a key and the socket is underneath it
if anyone is going to charge you over 40 quid to do it then here is a link i would recommend
i have one of these and they are ok
not great just ok
