Original gateway long code long. new gateway longcode short ?

Hi guys.

Changing a golf 07 gateway for a updated one.

Installation list all ok..no issues.

Old gateway long code is about 12 digits and new gateway long code is only about 6. Cant input original long code into new gateway.

Issue i have is that new gateway thinks its left hand drive with fog and reverse faults.

On the old version gateway the right hand drive box can be ticked to sort this but the new gateway with the short code does not have this ?

Any help please. Have seen this twice now...cheers....
