If you think changing the headlight bulbs on the face lifted XF would be the same easy 3 bolts as the previous model your in for a shock!
First off as before the headlamp unit must be removed, however once the bolts have been removed the unit will not fit though the hole. (not even close) also the bolt that you could see inside the wheel arch is now behind the arch cover
Remove the two bolts from the front of the unit
remove the three bolts on the inside of the wheel arch and cable tie back to the wheel
Remove the two bolts on the inside of the arch cover, one for the headlamp unit and one that clamps the bumper to the wing
Remove the five bolts that hold the front grill to the car to allow the grill to flex out
Pull the bumper at the wing down only as there are two locating pins attached to the bumber
The unit can now be removed but dont forget to unplug the unit.
My 2011 face lifted has D3S Bulbs not the DS1 That Halfords help desk had on file for the newer shape upto 2014
After all that changing the bulb will seem like child play.
