What's the service interval for this? Mine is a 16 plate and serviced every year at a mains dealer. I don't ever recall being asked/told to change the diff fluid.
Thanks!

Every 5,000miles for my Plus 8 with BTR Limited slip diff is quoted in the handbook.
I do my own servicing and it was clean as a whistle at that so now do it at 10k and it's still clean.
