Hello All,
Took my car for its yearly ITV (MOT), and all ok except for emission test, it failed! I don't know if it's possible to get an idea of what is at fault by the reading, but here they are...
There is less than a 300km's on the car from last year to this year.
Last year CO Ralenti 0,02% Ralenti acel.: 0,01% - Lambda: 1,006
This year CO Relenti 0,71% Ralenti acel.: 0,49% - Lambda: 1,009
Does this make any sense to anyone? I'm sure there's articles about emission issues on here somewhere so will be checking them out anyway, but if anyone can direct me to a good article about a process of ilimination to sort this out, that'd be helpful and appreciated.
Regards,
Ivan
