F10 M5 - handing keys back (lease) - rules around servicing?

[Tonyc32]

Hi all, in March I hand my keys back for the M5 as my two year lease is over.

At the time I only opted for 8k miles PA and this was more than sufficient. However, a change in job saw my miles increase significantly. I'm on 13k miles with about 5 months to go.

Regarding the 16k mile service.....what are the rules? Do I have to pay for it if I exceed 16k miles? I'd hate to have to fork out for a service for a car i'm about to hand back!

Thanks
