just hought id ask as the mot system is linked up to vospa etc and they test the emmision with what vospa says it should be right, so how do they do it on imports etc? as mines only registered as a 2.0 subaru 4 door saloon?

so how do they get there base figures for emissions test?

just asking as im decatted pmsl and mot coming up

 

ooop

 

The car goes through a bet test first, (basic emision test) with default settings. If your car fails this, it then has to be tested under the opropriate settings for the car. If the cats still fitted it should pass the bet test no problems.

 

some earlier classics can pass no cat

 

True, but i havent had one yet1

 

It depends on the date of registration / first use. Before 01 08 95 then itll be tested as a non-cat car; ie CO2 under 3.5%. If its a later car then it needs to be under 0.3%.

its an import mate so its prob registered a few yrs ago

and what your regarding to is the uk law? for around k reg?

 

simon , i tried telling a fellow user the same a while ago and then they were bombarded with other stupid replies, u r exactly right, my local mot tester says if the car model aint listed on the data base then it just will get the bet test and thats it, and we all know that a resonably healthy and hot sub will pass this without any cats, supose its how generous u r with the tester at xmas, cans and tabs make all the difference!!!!!!1

 

so whats the quota for the bet test?

 

The figures are in my first post; and the information is taken from a flow chart in the MOT Inspection Manual (July 1998). If the exact model isnt listed (which it cant be where your car is registered simply as 'Impreza'); the allowable CO emmissions depend on the vehicles date of first use. Simply, before 010895 and it needs to be < 3.5% (this is a 'non-cat test') and after after it needs to be <0.3%.

ok that does make sence thankyou, so what do they do om imports? as some will be 2005 registered 2004 etc, mine was registered in uk in 1999

 

For an imported vehicle, the declared date of first use is relevant; not the date of registration in the UK. Cars (first used on or after 010895) for which you cant find an exact listing still have to have CO emmissions of less that 0.3%.

 

but imports wont give a date just a year, ie mine says declared manufacture 1995

 

then it will be 0.3 emmisions

thanks ill bolt up me mates cat then

 

Youre missing the obvious arent you? The V5 may only list the year, but the registration prefix (which changes on the relevant date) will dictate which standard you have to meet..........
