I did this on my CCC in the 630i when I did the MASK to CCC upgrade. The CCC unit was from a Polish car. I believe that mine auto selected the Ireland when I default coded the unit so I suspect got your case you'll just need to change the country setting to Ireland using NCS Expert. Look up the MASK coding options on NCS Dummy and it will give you the options. I'm away at the minute but I'll try to check it when I'm back tomorrow.
