Hi Grant,
Sorry, I missed your previous post!
I've bought two XF-Ss from Arun a 2011 and more recently a 2017 - I assume you've meat Duncan, Andrew and the rest of the crew there by now?
I would suggest a chat with Andrew about the timing belt, etc., if you haven't done so already, although my understanding is that it isn't due for several thousand more miles.
I'm just coming up to the first anniversary of getting my current one - MoT next week!
Only problem I have (which will mean a chat with Andrew) is that my glowplugs are reluctant to do their stuff in cold weather - no a problem atm, of course, but need to get them (or the control module) sorted before Autumn!
Enjoy your XF!!!
Ceers,
Jon
