Bloody hell. Same situation again this year - passed everything swimmingly and failed miserably on emissions.....every year it seems to be emissions for a different reason - now I don't even know what to try.
This time I did a car reboot / reset and gave a good run before the test, but the CO2 was massively over the limit, Lambda was slightly out. I need to check the blink test again tonight, as I think the air intake control sensor fault comes back after a while, even after I replaced the part last year.
Annoying to say the least....

Looks like I may have to try a few things in order to sort. How much do people pay mechanics to check the emissions (multiple times) ? Probably about €40 a pop is it ?
