MOT Emissions

Mine failed on the CAT last year, a new one solved it.

Hi,

Just thought I would mention that high CO2 readings can be as a result of a hole in the exhaust. I had a tiny hole, less than 2mm, and the car failed on CO2. Stuck some exhaust putty on the hole, and hey presto passed straight away.

Lamda on the other hand does tend to suggest a failed cat. Could also be a failed lamda sensor or cat not hot enough. My pennies worth, is be careful changing the cat for an after market one, they are not as good as the manufacturers ones, and can cause EMLs to come on and will fail a lot quicker.

This is true. I paid only £150.00 fitted for a replacement - bargain basement price! I wondered how long it would last but it's done a year. I dunk mine in cold water regularly though, and no CAT likes that, so I reasoned that it may be cost efective to hve a cheapie put on ratherthan ruin an expensive one by abusing it.

December - February this last winter I was breaking ice when offroading through water at our club so the CAT really couldn't have liked that!!!

I gather that MOT means something to do with an annual roadworthy scheme? Glad they don't have anything like that here in Victoria, would sure cramp ones style :whistle:
