    Hi Guys,

    just been snopping on this to see if there was anything here to help but couldnt find anything..

    basically i have a 2003 octavia 1.9tdi that i am after spending a small fortune getting jobs done, (Injectors, egr valve and new suction hoses,) i want to hold onto the car a it is a good solid car for the girlfriend and has very low miles..

    its still not putting out proper power as it used to be so i was told maybe my cat was stuffed and that i could remove it and would have no effect on NCT..

    i was going to remove it and break the insides and put up again as it would be empty and couldnt get stuffed again, ju

    just wondering if anybody put a desiel car through nct with no cat or a dude and if it had any effect with emmissions or anything like that..


    any help would be very greatfully appreciated

    Won't affect nct, as it's only a smoke test, not emissions. You could drill/knock out the insides of the cat, or weld a pipe into the exhaust either.
    I have seen cats block solid before myself.

    Did you try driving it with the exhaust temporarily removed to make sure it's a blocked cat? Tbh I didn't think that era Octavia had a cat...

    And no care in the world about dirty diesel emissions. Shame the NCT only ever tested smoke in diesels and not NOx or CO2.

    I'm not advocating the removal of the cat, just to temporarily remove the exhaust to see if that's where the problem is. A ten minute spin down the road with the exhaust removed will hardly kill the planet.

    Not having a go at you, just more that the ball was dropped during the diesel boom of the 2000s.

    Just a smoke test is laughable especially when petrol cars have had some form of emission test since the 1994 (think it was only an idle test before that?).

    I don't think it's that easy to do gas analysis on diesel as it is on petrol engines. As far as I know diesels only produce high levels of nox in very specific circumstances, light load highish rpm with an almost closed throttle etc

    Diesels? I may have a crawl under the Aul lads 02 Octavia, with the way he drives it must be like a clinker at this stage...
