Gutted! MOT Failure

[Mr Jones]

Well, after 2 years of being off the road and a substantial amount of work, the clio went in for its MOT, and it failed.

Emissions were way too high at idle and fast idle, and there is a crack in the top of the exhaust mid section (wouldn't have expected this from a stainless magnex).

What is causing the emissions to be so high i dont know, is there a chance the crack could be influencing this??? Or maybe the cat or lambda is knackered??

Not bad going though to be honest, fairly pleased there is nothing too drastic to sort out, but i now have 10 days to sort it out or i will be paying full wack for a retest.

no emissions easy to sort out but crack in your exhaust will not give a good reading so sort your crack out ok m8

how does a crack in the centre section affect the emissions at the tail pipe?

affects the lambda reading

 

[Neal R19]

but how though?

 

[Gray-16v]

where is the lambda on the 5, surly if the crack is after the lambda it will have no effect whatsoever.

gray it was the clio not the 5 matey (you miss read again m8 or is it because your old and your eyes are goin abit blind lol)

 

[Chris H]

the exhaust will draw in air through the crack thus leaning out and affecting the lambda reading. Taking it outside the limits

Think I'm just spazticated :? either that or wanking really does make you go blind :wanker:

 

[Mr Jones]
