DPF problems JAGUAR F-PACE (X761_)

Had problems with dpf warning light.  Wouldn’t regen.  New throttle housing installed, air egr pipe and fuel filter housing cleaned. Dpf cleaned and reset.  Front prop shaft, complete exhaust system and cross over pipe to bank 1 removed and cleaned.  After 10 minutes driving Amber dpf light on, after 5 minutes green light saying its cleaned, then engine light comes on and red dpf full light on.  Dpf is 28% full.  Earliest date to put it into main dealer is 5th July.  Any ideas?
