Spoke to a very helpful chap in Harrogate that repairs LCM's and although mine is not one he can repair he spent quite a while educating me in the world of LCM's.
Apparently the one I took out was a YWC500280 which he thinks is wrong, the one I replaced it with is a YWC000540 which is also wrong and not worth messing around with. He suggested I look for a YWC500281 which will be easier to code if required. I had a search on fleabay and found a "Headlight Control Module Ecu YWC500281 05 Range Rover L322 Facelift" so now it seems I have a FFRR built in 2004, registered in 2005 and may have a factory fitted facelift.

This is the mid-life facelift (also known as the 2006 facelift)

Confused, you will be. Tune in for the next episode of FFRR.

New LCM fitted and all seems good. I even found a use for my Venturcam.
Unfortunately this one will not let me change the VIN or Mileage, maybe I need to drive a few miles first. I will have another read of the code and see if it changes in line with the mileage increase.

After a week of searching and finding nothing on the tinterweb figured this may help someone, someday, somehow.

Stored for future reference.

Code for YWC500281 fitted to L322 Vogue TD6 2005 facelift.

Thanks to everyone for their input, not only have I learnt a bit about LCM's, I have also learnt that cake can be used as currency, and that I have bought the most confused model of L322 available (unless you know different)

Most fattys 2004 - 2007 (dash facelift) can be made up of who ever was in charge on the day !

JLR still used the BMW key (till 2008/9) and remote fob system uptill the 2010

Mileage and VIN now coded so no tamper dot anymore
