Hi, my hijet just wont pass its mot, 3 times it has failed on emmisions. Ive changed the cat and put on a new exhaust, new plugs,new air filter, cleaned out inlet manifold and all the injectors have been cleaned, please help dont know what else to do and my garage seem stuck too!!!:sad:
Was the engine HOT?
Coolant must be at running temperature when emmision is tested. Take it on a fast 20minute cruise [70mph on motorway] and teat it on arrival.
or
The MOT testing centre's machine needs testing.
