VW Touran Failed MOT
Discussion
Hi Guys
2006 Touran, petrol engine. Just failed it’s MOT on the following, any ideas?
Exhaust carbon monoxide content after 2nd fast idle exceeds default limits (8.2.1.2 (b))
Exhaust Lambda reading after 2nd fast idle outside specified limits (8.2.1.2 (c))
Exhaust carbon monoxide content at idle exceeds default limits (8.2.1.2 (b))
Exhaust emits excessive dense blue smoke during acceleration (8.2.1.2 (g))
No signs of excessive engine oil usage or a leak, no head gasket signs, and to be honest no excessive smoke whilst driving? I followed it home! No oil in exhaust either? No engine warning lights, no loss of power?
Any ideas? EGRValve? PCV Valve? Blocked breather pipe?
Cheers
