MY2010 TDV8 Service Due (But When)?

Dash gave a warning (SERVICE DUE) this morning at 11 months and 13,500 miles.

Fine as I expect it is the close proximity to the end of month 12 that counts as we were 'told' it should make it to 15k miles before a service is due.

But when is it due in terms of miles. On the older FFRR cars (and most BMW's come to think of it), you get a mileage ‘value’ warning when the service is due. This just states SERVICE DUE. Had a quick drill through the onboard screens (dash and clocks computermebob thingy) but cannot not find anything stating as value?

Anyone seen anything remotely interesting for this please?

The service is free (we have a voucher for it) But wait till they see the list of bits that don't work (aux heater key fob), the bits don't quite work as expected (seat memory system nothing short of useless) and are coming unstuck (passenger step top cover is delaminating and coming apart) It will be like a new car when it comes back  Currently running FFRR MY10 TDV8 3.6L and a Disco 3 XS Commercial (tank like but very effective as a Company van). Plus one mint condition Track Day Car in the form of an E36 M3 3.2L Evolution circa June 1996 with lots of go faster bits and only 52k miles on the clock! Oh, plus a few bits to make it slow down really quickly as well! Luvverly.

My MY10 displayed service due in 1000miles. Think it was the same for the discos. *Gone* Discovery3 HSE
