That is also a problem, as from 2009 it is illegal to fit none type approved cats as replacements. Replacement cats MUST be to same EU type approved spec as fitted from new. None approved cats are cheap approved ones are not. Regulations mention unapproved suspension and brake mods. This could encompass a lot of things, lowered suspension none standard shocks, discs, pads, the list could be almost endless. How they would check for some mods is open to debate. But as all P38s have air suspension on their type approval, a set of coils would be a pretty obvious mod. It depends how retrospective they make it. I would think maybe they will set a date, otherwise 99% of boy racer type and a lot of off road motors would be instantly illegal. Unless the government see it as an opportunity to rid the roads of older vehicles. Would not put it past them.
if vosa is going down the type approval route then wont land rovers(all cars for that matter) retro fitted with lpg fail as its not on the type approval sheet?????
