Lexurf IV.

[BUSHWHACKER]

No need Alex, it's all relevant stuff for this section.

When I take the Lexurfs for MOTs, the tester sticks a probe in the end of the exhaust and the emmissions must be within a certain limit both at idle and 3000rpm.

No...it's all very relevant. When a vehicle also falls just short of an sva test, but undergoes a major modification( á la lexurf), you have to take into account, the original vehicle was uncatted.

i had a cat inmy truck



the little fu**er scratched me when i tried to get him out...

Oops, did someone say cats?
Personally I would fit them if legislation required them, even with a friendly MOT man you could still get pulled by VOSA roadside.But having read the comments from the more knowledgeable out there if its grey I wouldn't bother, spend the money on some more lovely soulnd making juice!

It's not a grey area, I've said what the test involves, the truck can still fail on emissions. An emission test print-out is handed over with the MOT.

If testing a vehicle with a cat because thats what the flowchart says ( post Aug 1992 and on the database) how could you do a test if it had no cat, dont they fit a lead to the lambda sensor for the test ?

The cat it's self does not get tested unless the vehicle is post 8 2002

Are the allowable emissions for test purposes not different depending on whether a cat is fitted or not. Would that not mean you were almost certainly doomed to fail ? If the vehicle has no cat yet the database says it should have, would that not be a fail in itself?

They will be slightly different, but (in my experience) a vehicle with the cat removed will pass its emissions test so long as the rest of the gubbins are OK. I don't think a missing cat. is grounds for a fail, just like no ARBs isn't a fail.

Is this too much of a thread hijack ? Should I delete this and move it to general?

No, it's more relevant here than in general.

Sorry, scan read the thread qucker than my brain could process it....
So to clarify it just needs to pass emissions. If a cat helps then great, but if it doesn't need the help it doesn't need the cat(s)?

Yep, as long as the emissions fall within the parameters it'll pass. They're tested with a hot engine at idle and at approx 3000rpm.
It's tested as a cat-less vehicle.

Well it's never been asked before, and for once (apart from Richard...shame on you ) the answers were sensible and definitive.

lol, its easy, a 1992 surf will have to pass the emission test for a 1992 surf, regardless of what motor is in it.
pre 1992 petrol cars have less to meet, 92-to 95 go by a official book, if a match isn't found its CO<=3.5% and HC<=1200ppm, after 95 the levels are tougher, being CO<=0.3% HC<=200ppm, which is almost impossible to achieve without a cat, or Running on LPG.
I think from 2001ish you HAVE to have cat fitted regardless.
