Just failed its mot on the emissions! Any one else had the same prob? Any advice would be welcome CHEERS!!

Will let you know when I get chance to talk to the test centre about what's happening with my car. Hopefully not but hey you never know

Any comments such as a leak found or anything?

Hi, i've been reading a few related posts and its looking like the CAT or LAMBDA or possibly both the emission results read FAST IDLE CO 0.3 FAIL HC 200 FAIL LAMBDA 1.03 FAIL natural idle test CO .35 PASS

fast idle CO 3.95% HC 207ppm LAMBDA 0.91 natural idle CO 0.16% does using super unleaded damage the lambda? Read up on lambda's they normally need changing between 30 n 50k my mileage is 61k i had a diagnostic guy try to read the ECU but it kept kicking him out does the red master key need to be used to read it?

I had this kinda problem not long ago on my old fiesta - turned out to be the lambda was knackered. Replaced it and it passed
