I have to remove the BCU from my vehicle listed above and refit the new coded one. How do I do this? What do I disconnect first on the battery and unit please?

Here are the instructions on how to replace the BCM with a generic guide to help walk you through the steps. Also, we don't have this vehicle in the states, but I think I found the correct application. Please let me know if this doesn't work for you.

You can get a preprogrammed unit by searching Google or Ebay. Check out the images (below). Please let us know what happens.
