MOT EMISSION TEST

[pal944]

Just had my S2 mot it passed ok but the guy did not do a emission test said they don,t need to do one as its a pre 93 car even if its got a cat. Any one else had this because they tested it last year.

They should have done an emissions test, see guidelines below:

First used before 1/8/1975 - Visual test only. Failure for excess idle speed, dense blue or black smoke for 5 seconds at idle or during acceleration up to 2500rpm or half engine max speed whichever lowest.
First used between 1/8/75 and 31/7/86 - meter test CO <=4.5%, HC<=1200ppm.
First used between 1/8/86 and 31/7/92 - meter test CO<=3.5%, HC<=1200ppm.
First used between 1/8/92 and 31/7/94 - advanced emission test (CAT) if its running on petrol when presented, to the vehicle specific limits usually around CO<=0.3%, HC<=200ppm and Lambda 0.97 - 1.03. Remember from 1st August 2001 a basic emission test will be carried out initially.
