1999 polo 1.4 petrol 40,000 miles The car passed every MOT since 2006 with no advisories except one year 2016 when it failed. It has since passed 2017, 18 and 19
not my car, but I was looking at the MOT history and I noticed it recently failed on
[b]”Exhaust emissions Lambda reading after 2nd fast idle outside specified limits (7.3.D.3)”[/b]
2 days later it passed
Please tell me what sort of things can cause this and what sort of work would have been done to fix it?
Thank you
