My 146 is now clear on its Mot apart from the emissions, as follows:
Fast idle:
CO = 0.56% [should be =< 0.3%] = FAIL
HC = 78ppm [should be =< 200ppm] = PASS
lambda = 1.011 [should be between 0.97 and 1.03] = PASS
Second Fast idle:
CO = 0.44% [should be =< 0.3%] = FAIL
HC = 98ppm [should be =< 200ppm] = PASS
lambda = 1.011 [should be between 0.97 and 1.03] = PASS
Natural idle test:
CO = 0.50% [should be =< 0.5%] = PASS
MoT test centre say it's probably the cat; reading this forum I'm not so sure... what should I try first to troubleshoot this?
Car is a 1.8 with 101k on the clock. MAF is genuine Bosch. I do not know when the MAF or lambda sensor were changed.
I have MultiECUScan and will be connecting this tomorrow - any suggestions on what to check?
Cheers,
Jeremy
