CTS?
Stick some redex in the tank before the test and rag the car before the test.

Give the car a good service.

Or

have you got cat back system on or anything like that? mine failed mot las week on emissions. i put standard silencer and backbox on and also got rid of any air leaks in exhaust and replaced induction kit with standard air box and it went through fine even though when it failed the carbon monoxide readings were double the limit
