Brothers 106 GTi has failed mot on emissions. I dont think its possible to adjust it manually being totally controlled by the ecu.
Its only a tiny, tiny bit above passing. Personaly I dont think they had it up to temperature when they tested it.
Anyway, is there anything I can do just to bring it down a bit to make sure it goes through?

Take it out and hammer th eliving daylights out of it before testing. Worked on my mates old VTS

gurnE

That should work

What was high?

Set of plugs and an air filter wouldn't hurt

carb cleaner in the air filter and as above kick the shit out of it, my old car did it but i took the air filter off and emissions went down strangely

Has your lambda sensor failed? They are very prone to it as are the Saxo VTS.
Is it running roughly? Sometimes it takes a while before it logs a fault on the dash light......................speaking from experience here

Yeh thought of giving it a good blast before hand

I think CO level 0.32 at idle and also slightly high at fast idle.

Had plugs in a service just before he bought it a couple of months ago. Dont suppose a new set would hurt just to be sure.

Just remembered its got a K&N on. Maybe something to do with that...?

RSBen

Runs fine I think, he hasnt said otherwise. Wouldnt it be miles too high if that was th case though?

RSBen

Maybe helped it breath better ? ?? Just guessing here....!!

i dunno what it did but it brought emissions down and it passed

urm, try plugging it in see if theres any codes if you know a mechanic with a machine?

try a fuel filter maybe? 02 senser? does it have a cat fitted? [could the last owner have hammered it out?]

Holding it on the rev limiter does work though!
