it was simple to replace the led unit once i had obtained one. price here in australia aus$ 900 (thats right 900) and subsequently got one from UK for approx $200. remove instrument cluster (post on this elsewere)remove two screws holding led unit unplug unit,replace with new , replace plug, replace cluster.....voila!!!
the only "tricky " bit was that there are two pin configurations (maybe F and C ???).i just orderd as a direct replacement (4 pins...mine is in C).
i soldered the new lead to the old as i lost it under the fuse box!!!

however it doent seem to have backlight. is this normal?

was it worth it? yes to me because i am trying for all luxury systems working.

systems comleted:
headlight wiper/washers
outside temp
cruise control
power seats
central locking

presently working on climate control!!!!!!!!!!!!!!!!!!
then secureing front seatbacks when underway thanks to alll who have helped
