MOT Fail today, help needed

Post by adeel43 »

Took the car in today almost expecting something to be wrong but wasnt expecting it to fail on emissions.

It failed on CO...

Fast Idle Test
CO - limit 0.3% reading 0.43% FAIL

Second fast idle test
CO - limit 0.3% reading 0.58% FAIL

Natural Idle test

CO Max 0-.50% reading 0.44% PASS

Now I did notice a hissing sound when having a poke around ealier (the car was for the first time running really rough today after the MOT) and noticed a hole in onme of the pipes.

Now could this casue it to fail the emissions?

Also what is it and how much is a new one!
