A / B service question help

[Barry123457]

Hi my 2012 XF is due it’s service ,probably an obvious answer but  how will I know which service to have done ? I have looked on the service history and only the first few years was A or B ticked , the last few years don’t have a tick in either box so I don’t know whether A or B have been done ? Thanks in advance

Hi Barry,

I guess the easy option would be to assume that the unticked services alternated as they should have done, so counting forward you could work out which was done last time and move on from there. On the other hand, you might prefer to play safe and go for the 'biggie',

Cheers,
Jon
