rusty94disco Posted August 30, 2009 Share Posted August 30, 2009 Hi i did my 94 tdi a month ago and it passed its mot last week no problem. All the mot tests is smoke. car feels much smoother. i paid the extra for the flexi down pipe and fitting was no problem just a bit of wiggling about.

karlo Posted August 31, 2009 Share Posted August 31, 2009 Yes, do to the cat on the diesel being a particle filter not a cat, mine has been through 2 MOT's without it fitted. Quote Link to comment Share on other sites More sharing options...
stageonesimmo Posted August 31, 2009 Share Posted August 31, 2009 I hate to this, Karlo but - Rubbish! That's an urban myth. Its a single stage catalytic convertor - particlate filters are not nor have they ever been fitted to any production landrover - they require complicated monitoring and soot burning systems involving ignitors and fuel supplies - none of which is fitted to any LR exhaust. When the 300Tdi came out particulate filter systems were in their infancy and were even too expensive/unreliable to fit to large commercial vehicles, let an already basic 4X4. Although the technology is now more common-place (i.e. the latest Pugeot diesels are often fitted with them along with a smattering of other major manufacturers), its still not very widespread and its definately NOT fitted to 300 TDi discos............ However, the gist of it is right - the smoke test checks opacity/density and not chemical composition which is what a cat changes meaning that taking off the cat leaves no testable evidence behind.........
