Hi

So you may have seen my other thread about MOT failure and high emissions.
One air filter replacement, some oil and italian tune up later, its still failing.

I assume the Cat has gone. But that's as far as my knowledge goes. There's more than one cat right? So do I replace both, or just one? Car is a Standard Turbo 2000 with PPP. Is there some sort of prodrive cat fitted instead of a standard one?

thanks

 

What are the emissions readings. could also be lambda failure

 

Not sure, its excessive carbon monoxide.
I think a couple of days ago it was 40-50%. Today it seemed more, but the car wasn't really up to temperature.

 

The correct results will enable a better diagnosis. The test centre should have given you a print out. Without it. Its like p**sing in the wind

 

They did not. He just kept telling me what the result was. 41% first test, 51% the next.
Better make a trip back there then

 

Nope, its me who's an idiot. I had the right paperwork all along.
In short, its failing on fast idle test, where CO is concerened. Looks all good apart from that.

it says:

Test One:

fast Idle test Limit Actual Value

CO =<0.2% 0.51%
HC =<200ppm 38ppm
Weird symbol 0.97-1.03 1.004

Test Two:

fast Idle test Limit Actual Value

CO =<0.2% 0.41%
HC =<200ppm 22ppm
Weird symbol 0.97-1.03 1.002

Natural Idle Test

CO =<0.3 0.12%

really appreciate your help turbotits, and anyone elses
