Freelander 2 (LR2) Which ptu?

Need to replace the ptu in my 2008 auto fl2, however when I have looked at supplies I come across two numbers.
7G9N-7L486-AB
6G9N-6L486-CF.
I am assuming these are for pre and after serial numbers but can't find any info anywhere.
Has anyone any information they can assist me with.

Regards
Graham
