Instrument cluster - how do I code a new one

[Goran]

It looks like I will need a RHD instrument cluster with a mile-speedo to be able to register the car in the UK.
Looking at a few threads I see that the facelift insturment cluster carries an imobiliser and has to be coded to the keys?
Does anyone know how to do this using VCDS?

Othe alternative I was thinking of, can the speedo dial be detached from a RHD instrument cluster and re-attached to my instrument cluster? Are the dials glued in or can the be unbloted?
