Hi all,
 
	Re XF 3.0 V6 diesel.
 
	Thanks for the advice on this thread. Having a DPF full, consult handbook message and following the handbook advice of a constant speed long run which failed to fix the problem. I then tried the sport mode 3rd gear 3500 revs method above on a 40 min blast down the M50 and back. The following morning,  its all fixed.
 
	Guess I'm going to have to find some excuses for a few longer trips.
