    Is it true they make you sign a disclaimer when you bring in a diesel car ?

    Yes.

    Yes


  • Registered Users, Registered Users 2 Posts: 73,478 ✭✭✭✭colm_mcm


    Yes, it's in case the engine goes wallop when they're testing the exhaust emissions

    I've heard it, it's in the NCT manual, but I was given nothing to sign when I tested mine in October.

    This would be the one about the timing belt.... I'd wonder about that disclaimer..... One would assume that NCTS would still be liable for their employees negligence despite the disclaimer. Has anybody ever actually read one? What does it say?

    What's the difference between testing a diesel and a petrol for emissions?

    is it that diesels have lower revs and the nct rev the bejasus out of them?

    Revving the engine wouldn't usually wreck it, it's just to save bother I reckon. It would make any case against the nct pretty weak.

    Diesels have rev limiters anyway

    Smoke test as opposed to hc and ppm. They bring the engine up to its redline to test that.

    I know when mine goes for it's test, I'll make sure it won't rev above 3k rpm. They won't be rebuilding it if it goes wallop!

    I think it just states you are agreeing the car is in a fit state to be tested and the timing belt has been replaced in accordance with the manufacturer recommendations. In other words if it snaps while they are revving the crap out of it it not there problem

    And they don't smoke test the petrols?

    It's a smoke opacity test that the rev the engines hard for. Doesn't apply to petrols

    Well petrols don't produce clouds of black smoke (:pac:)

    Petrols steam when cold but shouldn't smoke. Otherwise something is radically wrong!

    DUH! Sorry, having a stupid day :) Too used to petrols and don't pay attentions to diesels.

    Must watch out when stuck in traffic behind a diesel (with the windows closed :) )

    If it's the diesel you are referring to than they won't pass it :)

    How are they being negligent ?

    Not to worry! :)

    Generally diesels don't smoke much anymore, much cleaner emissions and rarely a puff of smoke from them :)

    Except mine :pac::pac:

    There's 2 ways I do this: screw it right down or set the max rev screw really low. All mechanical, done in a few mins :)

    Same crack with the DOE, if it can't rev, it can't smoke, it can't fail on that :)

    Maybe other centres are different but that's how it is round here...


  • Posts: 23,339 ✭✭✭✭ [Deleted User]


    For the NCT they have to verify the rev limiter works when it should, if it doesn't they stop the test. If it can't rev it won't hit the limiter so you fail ;)

    For the nct, the engine has to rev close to whats in the makers specs or it wont pass, to stop people turning them down for the test:pac:


  • Registered Users Posts: 265 ✭✭GE90


    What about newer cars that wont rev above 2.5k to 3k when in park or neutral ?

    Hmmmm, maybe they were up near the limit and I didn't realise it... Didn't fail so that's all that matters :)

    Still didn't stop me turning it down though :pac:

    there's a low cut off option for vw's, audi's , bmw's etc , that have a limiter on them. there is a by pass system on vw's and audi's to check whether they have a factory cut off or after market cut off. diesels are not revved to the limiter anyway.

    how to by pass that limiter ? on my wifes vw polo diesel, cant rev over 2.5 k, while parked, if start drive, press clutch and rev, then limiter not working.
