these used to be available to x part service centres from omitec, but awhile back they changed the policy where x part do it themselves for a charge.it requires a fax back form from them to be filled in by x part centre with all items fitted to that vehicle they then send ZCS codes back for entry by T4. PS i am not certain what you want to do requires the codes, willhave to check at work. HTH HELPS GEOFF.
