The car (Mini one, 2007) today failed a second time on the emission test with the following reading:
CO Max: 0.20% Reading: 0.25%
HC Max: 200ppm Reading: 367 ppm
second fast idle test
CO Max: 0.20% Reading: 0.63%
HC Max: 200ppm Reading: 399 ppm
The first time it failed I was provided with fuel cleaning liquid and was told to follow the instruction and return again for a retest, which was also a fail.
I am visiting a BMW specialist to have my car plugged into their diagnostic system for codes. Can anyone suggest a likely culprit which could be at fault? Based on research it would suggest a bad 02 sensor or catalytic converter.
update: After visiting the BMW specialist today,he suggest a new 02 sensor and cat converter. I convince the garage technician to firstly install a new 02 sensor and seeing if that resolves the emission problem. The work will be carried out tomorrow.
I will report back tomorrow if the emission problem is rectified. Pray for me guys!
update: The garage technician must be a member of the MoneysavingExpert forum because he just saved me over £300.
Yesterday I reported that a new catalytic converter was required to resolve the emission test issue. However before replacing the cat, the technician cleaned the old catalytic converter using a cleaning solution and BAM!!! I passed MOT.
If anyone else is experiencing similar problems to mine, run a high-quality cleaner before spending $$$, my 2 cent.
