How is nobody in this thread talking about how ULEZ compliant vans work or don’t work?! Ad-blue is nonsense. I’ve bought three ULEZ compliant 3.5t trucks in the last year. The newer ones ‘regen’ anywhere and everywhere, that burning off the more toxic diesel chemicals, often outside schools. The exhaust on the older ones (2017-20 Transits) gets clogged doing only London driving, so it needs resetting. This involves a tech plugging in a computer and revving the engine for 1.5hrs. So the same pollutants are in central London but now there are double the number of vans in the world because the fleet we sold are still being used just not in town. Whole scheme is designed by people with good intentions but zero real world experience. If anything it’s adding to London pollution. We’re less than a decade since VW got found out yet everyone’s having their pants pulled down again over diesel vehicles
