It varies dependant on the car

According to my last test, Fast idle co is max 0.20 and natural idle is 0.30.

Best thing you can do is blag it... tell the MOT garage its a 1993 T5 with a private reg. Pre 1994 didnt require cats if I remember correctly.

co2 = 13.08

HC = 1117 ppm

do we think she's running a bit rich? a well the boares should be nice and clean after that wash

Or offer to buy a bottle of their MAGIC cat cleaner and hopefully he'll take pity on you and give you a pass whilst it gets to work

Sadly if it's ever been tested before under computerisation the VOSA computer will tell the tester what the vehicles year of first registration is regardless of private plates.
