like the rest say veg oil is the easiest way used to work testing and you could tell when on veg oil as a single rev of the engine is all that was needed and a pass then

Does using Veggie oil work on this new reader they introduced in December as part of some new legislation?

Re test Monday all suggestions gratefully received

No new ideas but..........

What was the fail results? You should of got a print-out.

If you try this veg-oil route, let us know the results.

Presumably any new legislation is for new models only and older vehicles will carry on at the contempery rate/method? Things tend not to be retrospectively applied. The emissions standards you need to meet do vary quite a bit depending on engine age as new vehicles are built to meet tight restrictions that old ones simply can't, seems logical to MOT them to the tighter standards they are now built for (euro1/2/3/4/5/6, T3 engines aren't even euro1!). All modern diesels have CATs and particulate filters so perhaps they are bringing in something to test CATs as as far as I'm aware, that bit currently isn't tested by the smoke test meaning you can just remove it or make it streight through (if it has to have one by law) and no one would be able to prove it was bust. All way to moddern for a T3 though.

If you don't rev them much they seem to do rather well on the smoke test (should be done at max no load speed). The 1.6's rev really high so bringing the max speed limit down a bit could help and yet still seem belivable? 4krpm still sounds like a max speed for a diesel and is all you'll manage with some beer mats under the pedal

I don't think there is such a thing for older diesels, there's just a visual smoke test I thought?

I just turn mine down about 1/2 turn and back up afterwards

.. and don't top it up with oil just before you take it to them, leave it fractionally low!

Thanks guys, I replaced the air filter, it had been missed out the last service so it had been in for 18 months and was black, I have filled the fuel filter with injector cleaner and blasted that through and I was thinking of filling up with BP low emission diesel, going to ring in the morning to see about retest.

That will probably do it... make sure its good and warm, good luck.

That is what I thought but apparently they have this new machine since December, shame was the tester looked at the welding and commented on how well up together it was

bloody good service with fresh oil, new air filter and properly set up pump timing etc etc... the hard thrash works a treat if the engine is in good nick.. if it isnt.. BANG!!!!. well its gonna be costly........

Too many people think they know the MOT regs, but simple don't. I as a tester have to look in the manual at least once a week! lol. The garage 'should' ask when the cambelt was last changed on a diesel engine and the oil level should be checked before a diesel test by the tester....A good set up and warmed up engine should pass a test no problems. Only trouble can be when you get an old fart driving round town at 20mph all the time, thats when you will see clouds of black smoke on the test...

Describes me perfectly

look at the bible yes but there is a cut off date on older cars think you will find its around kreg not a 72 k and the smoke visual then comes in so new machine or not the new machine will cover the new leg for newer cars etc but the machine will also cover the older regs too but every station works diff allthough they should all be the same the only way they will sort it is do like the germans etc gov run places and not sep places because everyone interperts the manual diff i do as other gresse monkeys do we had 2 guys in our place argueing one wanted to fail the other said no bible out if the tester is going to fail it they will no matter what norm find this at a garage where they undertake repairs just mot testing place you dont find that happening but norm dearer on the test hope it goes through for you but i think the veg oil is the easiest route then xplore some more rember the test is only good as long as you are in the station once you leave a police officer can find a prob as test standards dont always comply to the rule of the law

!

Well they did my about a month ago.

(Think) It had to be below 160 ppm after three revs.

Why ask when cambelt was done on a T25, there never was a replacement interval as with all non tdi vw diesels so you would be wrong to refuse to test even its origianl one.
