if it wont pass there's obviously a problem as they should pass if running properly...

I know you're trying to say that a car doesn't need a cat, but that is bo***cks. Especially for older cars. If manufacturers could get away with not fitting a cat, they would.

In response to Jimmy, it depends, do you have a de-cat? If so, just find a friendly tester or re fit the cat. If not, fix the problem.

You can try your browns gas generator if you want, but I am doubtful.

No cat fitted is a fail now regardless of emissions, one of the new mot rulesYes

Ah ok. Maybe they were compulsory to be fitted from 92 but could still pass a mot without? Not that it matters. No chance of mine passing without one lol

I've had my car pass two years now with my decat fitted I just presume that they are unfamiliar with petrol 306's as every other 306 in northern Ireland is a dturbo, and I won't be correcting them.

You're possibly reading Mei's reply wrong.

He's saying if you need to bodge it or find an iffy garage the there's a problem with the running of the vehicle.

    im talking hypothetically here. im still waiting for my v5 to come back before i can get my black (was blue) gti back on the road.

    as wishy washy as my methods seem and are.... for some reason im pretty lucky with my guesses....and the cat looks.....fooked and i figure it will be the reason for the fail. ive fixed everything else for the mot, my toolbox is just lacking an emmision tester.

    being a dingle here im gonna ask the question ive just realised i should of asked instead......will the newer exhaust/cat on my phase 3 xsi (mot ran out today) fit on my phase 1 gti????

    and in response to the browns gas Smile

    i use my proper cells now for my welding rig. i can get around 22 litres of gas a minute now at around 25 amps. its all to do with adjuting the PWM to resonate with your cells natural frequency to get a dramatic increase in gas production.

    my 1.4 306 had a lot more engine bay room to play with. this was also with my old naff primative cells and no PWM getting around 2-3 litres a minute at about 25 amps. with no real inbuilt safety.

    after the mot tester blew up the plastic manifold top on my 1.4 after being an idiot with my car. i kept it out of future cars.

    but you never know.......its been like 4 years and ive learned some things.....like how to hide switches and not tell people about your crazy and possibly dangerous ideas etc.

    The new rules (which came in April I believe) now state that regardless of emissions, removing a cat should now be a failure. Before it was law to have one from the factory, but would still pass an MOT if the emissions were okay, I don't believe they even had to check for a cat.

    If it's one of the rules which came into force (which I'm sure it was), they now have to check the cat is physically there - if it's not, fail.

    As said before, one way is to hollow out a standard CAT, so it still looks like it's present even though it's acting as a decat. Yes

    i built one a few years ago used to run it on a 1.5 Nad i found it was taking to much power to produce a usable amount of gass had mine up to 4 ltrs/min @40amps with no PWM

    have you ever filled plastic bags and lit them?

    If the testers are arseholes, we simply weld the cat heatshields or the cat's outer skin over the decat pipe (so looks like a real cat, but it's a straight through pipe).

    And if it fails on the emissions we use E85 which brings them down under the fail level Smile
