[QUOTE 4104049, member: 9609"]And I also think the MOT station has went a bit OTT insisting it is fitted, they were not mandatory until late 2009, so any vehicle reg after that date should be checked, but a 2005 car, I think they are being ridiculous.[/QUOTE]
Not so: the rules are quite clear. If the car had a DPF fitted as standard when new, then it must be present. Nothing to do with the year of manufacture. The MoT tester has no discretion in the matter.
Diesels are wonderful things, but inherently dirty. By nature they are solid and reliable, but the ever-tightening emissions legislation means that makers have had to devise more and more ridiculous solutions to get round them - EGRs, DPFs, AdBlue injectors and on and on. These are all essentially sticking plasters to get round the inescapable fact that diesel combustion produces a lot of stuff we don't like. I spend a lot of time on a motoring forum, and there are ridiculous numbers of people who come on to complain about rough running, breakdowns and expense, all related to the fact that the modern diesel is only really happy if run for long intervals at a decent temperature. Salespeople are still selling diesels to customers who only use them for shopping and local trips, when in fact they are totally inappropriate. The government gave us all those tax breaks to get us buying diesels, and now they are going to have to reverse them. My daily driver is a Mondeo diesel and I don't have any problems with it (56 reg, no DPF) but when the time comes I will be replacing it with a petrol. Higher VED and uses more fuel, but better for the environment and less risk of huge, life-changing bills.
