Hi Sofia,
I bought a 2017 XF-S last year, my second XF (first was a 2011).
Only problem so far is glow-plugs not working (cold weather only!), not sure if it's the plugs or the controller, but I need to get it seen to before next winter!
BTW, I'm an Essex boi too, from Tilbury, now living in Sussex, where you at?
Good luck with your XF - they're great!
