I paid about £400 for my service at 12,700. The Mobil Oil is the expensive bit.

I also took my XF into the garage at 17000 miles as I was getting a grinding from the front brake. There wasn't a problem, just a 'hard' bit on the pad which wore away after another 100 miles or so. Weybridge Autos didn't charge me for looking at the brakes.

Let us know how you get on. My second service is due in 4,600 miles.
