emissions problem
looking for advice on emissions failure mot. is it possible a small exhaust leak could cause failure or is it more serious?
|
A minor exhaust leak, can give you high lambda readings which could fail, as it's drawing air into the exhaust. What have you failed on? Lambda, hc or co?
|
post your readings mate and i'll try and help:thumb:
|
fail sheet reads; centre exhaust has minor leak of exhaust gases.
exhaust emissions; carbon monoxide content after 2nd fast idle, excessive. lambda reading after 2nd fast idle, outside specified limits. hope you guys can help, 'cause garage never advised of a fix to pass mot due to their diagnostic equipment playing up! would a new exhaust simply fix it? |
A minor leak of exhaust gases is not a failure in it's own right, but excessive lambda can be caused by an exhaust leak. Can you post up the figures my guess is it only just failed.
|
didnt get figures, just fail sheet and advisory. sorry i cant be more help.:wonder:

Yeah you really should have a gas sheet. Either way if you failed on excessive lambda and have an advisory for exhaust leak, there you go!! Get that sorted and try again.
|
will do! cheers for help guys. the search for loud goodies starts now then :norty:
|
Good luck, gotta start somewhere, trouble is once you start you can't stop!!
