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.
