Just after some advice please. Put my bug in for mot today and it failed on co2! Max 0.30% and mine was 49% at fast idle test and on the second test was 0.65%. Natural idle max 0.50 and it was 0.55%. Just been reading giving a good thrashing before the test would get it through. Can anyone confirm please?

 

What did the tester say??

 

They said nothing lol. Just it failed on emissions. My wife took it in as i was at work. But what i can make out its only just failed.

 

She took in at 15.40 and they did the test at 16.40.

 

It needs to be red hot and it will pass mate

 

Thought so. Will give it a good blast before i take it in. Cheers scoobyman

 

Yer mate and just say can they do the emissions stray a way and then thats it mate

 

cool. Will put a post up tomorrow and let ya know how i get on. Cheers again

 

happened to me a few years back failed got told to thrash the living daylights out of it before test , worked a treat the tester said what the **** have you done to it its better than a new car .

 

Ok mate let me no

 

Failed again!! Co too high. The tester said its could be due to having a tiny little cat welded into a de-cat pipe and it's not doing its job properly. We tried everything! Fuel additives and giving it a blast and testing it again but no luck not even on idle. So got it booked in to edm motorsport on Tuesday to get another cat put on and try again. Cheers for your help though.

 

It will be the 02 sensor mate, change it and all will be fine.
