I'm sure you won't get a direct answer here. Security is tight :wink:
Your best avenue is to call datatool:

or
+44 870 165 2414
There are troubleshooting and coding instructions downloadable off the site but fitting instructions are 'dealer only' or contact the help line with your problem. You'll probably need some numbers off the unit to identify it also.
