Yes, I take all your points of view and unfortunately my lifestyle and work changed last year which meant I no longer had to/could drive long distances in it.
Naively, I didn't realise it had a DPF filter initially, till the EOLYS fluid ran out. The Ford Dealer state they need changing at 75k but it still surprises me that they didn't mention it as it was guaranteed work for them and they must see this sort of thing all the time.
Thanks for all the tips on remapping etc. Any idea what this does to the emissions come MOT time and the fuel consumption? Does the car then pour out soot?
