I thought it went
MY08 original - electronic diff
MY11 - (2010 reg on) - LsD, blue steering wheel, DAB, HDD, Spider Alloys option, UsBlue option

Mine is a May2010, has spider alloys, blue steering wheel, DAB, HDD, and definitely has LSD, even though dealer told may they spoke to Japan and it didn't
Dealers know nothing!
