Hi,
 
	I have a 2009 3.0 D Jaguar XF [120k miles] and had the same issue pop up recently.
 
	I have now done the following for under £50 total [i.e no labour costs] and all very simple to do.
 
	1 Redex DPF cleaner [£10] one dose in fuel and 30 min drive on motorway & dual carriageway.
 
	This gave a couple of days grace to do the rest.
 
	2.  Air filter [£4.50] + Air Mass Flow meters spray clean [£10.00]
 
	3.  Fuel Filter Change [£21.00]
 
	Engine now revs up to 5000 with no issues at all.
 
	I hope this helps.
 
	Phil F.
