I had a similar experience with my 2011 XF 3.0d S Portfolio. The Jag dealer quoted AU$2500 for replacement front rotors and pads.
After a bit of research I purchased replacement front and rear dimpled slotted ebc rotors, red stuff pads and wear sensor cables for AU$1000 and paid a local garage 2 hours labour to fit. Whilst he had the brakes apart, I took the calipers home and did the red ceramic heatproof paint thing.
Big, big savings and great brakes.
