allelujah!! Carmo have just responded, they are still in business yay! In desperation I hit up every email I could find for them last night and just got a reply this AM so hopefully they will be able to help. Scott - don't delete your link yet ;)
thanks again Scott, I saw that post the other day too.. they are more available in the states as you say however I spoke to Ian at Motomatrix (the people who I'll send this to to reset for me when/if I ever get one) and he warns against it due to imobiliser and HP differences so I'm not certain...
These things are like hens teeth, anyone know where I can source a second hand 4S8-8591A-00 Euro spec?? Have called every breaker in the land, new runs at over £700 and I ain't paying that!
