Last few years the emissions have screwed me
2012 - replaced post and pre cat sensors
2013 - replaced main Cat
2014 - replaced main cat again
This year it failed again, CO excessive at both idles, hydrocarbons and lambda outside limits at 2nd idle excessive.
VCDS errors:
17584 Correction behind Cat
16517 Lambda response too slow
17566 MAP implausible signal
Checked for air leaks, re-taped the hoses just in case but found that the pipe to the top of the EGR was not secured - someone had not done up the jubilee clip so had been running like that for at least 4 months.
Replaced MAP and pre-cat O2 sensor, cleared faults, rescanned and all good. Got it back to the MOT tester with an hour to go before the free retest ran out.
fail!!
It seems to be running even richer than before and the tester said the cat could have failed...again? That would be the third in 3 years.
This is the emissions report and the handwritten numbers are from the retest.
