i've had a bit of trouble with my car, i bought it last January and was fine up until November/December time, then i kept getting a warning light and engine light and was told it was DPF related so garages tried regeneration and was ok for a few days then same problem.
eventually i got a new DPF fitted (not Ford genuine part) as was told the DPF was completly clogged as the regeneration's would not work any more.
i do mainly town driving but do tend to try and go further a field at least once a month. as i heard it needs a bit of motorway driving every so often to keep it clear.
i am a little concerned as car has started leaving fan on for a few mins when i turn off and engine sounds louder etc- i have read that this is usually car trying to regen, but i have been turning car off whilst regen is happening i think but the day before i did drive for 25 mins or so at 60+ mph, would this have cleared it if it was getting blocked?
im petrified that i'm going to see the dreaded light again and the limp home mode again.
is fan staying on etc an indication that dpf is getting blocked again and if so what can i do as like i say i have taken it out a couple of times this month for longer motorway style runs?
