#1: Mot fail Emissions Author: TattyWater, Posted: Thu Jun 19, 2014 2:25 am ---- My faith full little Pug has failed her Emissions test as follows.
Fast idle
CO : Limit 0.30% actual 0.50%
HC : Limit 200ppm actual 150 ppm - Pass
\ : Limit .970-1.030 actual 1.071
second Fast idle
CO : Limit 0.30% actual 0.58%
HC : Limit 200ppm actual 201 ppm
\ : Limit .970-1.030 actual 1.051
Any advise where to start to sort this out ?
Was thinking new cat and clean Lambda sensor ?
She is an old girl at T reg but only done 85K, and did have a loose joint to the back box.
Thank you

Are you using supermarket fuel or something like Shell V Power?
A good hard run on a motorway can be enough to give it a clean out and reduce the emissions to a passable level.
#3: Re: Mot fail Emissions Author: TattyWater, Posted: Thu Jun 19, 2014 6:39 am ---- I was given the car in Oct last year, but no idea when last had service.
Buying some Bosch super4 plugs today and have used up the last of supermarket fuel with redex in it. Now filled up with Shell advance.

You'll probably need a new lambda sensor too as it looks like your fuel is running rich
#5: Re: Mot fail Emissions Author: bodieanddoyle, Location: ColchesterPosted: Sun Jun 22, 2014 11:28 am ---- Full service, ie plugs air filter and oil change. Check for air leaks. Probably a service and half decent thrash on a dual carriageway with sort it
#6: Re: Mot fail Emissions Author: TattyWater, Posted: Sun Jun 22, 2014 2:24 pm ---- Thanks Pepole.
I have put new exhaust on inc cat,super 4 plugs and V Power fuel = CO level worse.
Going to do oil flush and change, oil filter and Lambda sensor tomorrow.
The car is solid no rust anywhere and only failed MoT on this, but does have I think, a head gasket problem and needs new clutch.
#7: Re: Mot fail Emissions Author: TattyWater, Posted: Mon Jun 23, 2014 2:49 pm ---- Done Lambda sensor, oil and filter change - Still wont pass Mot.
Failing on Co still at 0.60 !!
#8: Re: Mot fail Emissions Author: macca1411, Location: Westhoughton, LancashirePosted: Tue Jun 24, 2014 1:02 am ---- Have you changed the air filter?
#9: Re: Mot fail Emissions Author: TattyWater, Posted: Tue Jun 24, 2014 7:16 am ---- I took the air filter out for test !

#11: Re: Mot fail Emissions Author: TattyWater, Posted: Tue Jun 24, 2014 1:22 pm ---- Tell me about it, put on new cat,lambda sensor,super 4 spark plugs,new oil and filter,dosed the tank of shell v power with redex, spent best part of £200 and the fecking CO reading is no better !!
#12: Re: Mot fail Emissions Author: kwakzx7r, Posted: Tue Jun 24, 2014 1:37 pm ---- No offense but does it not occur to you to try putting a new air filter back in and then re testing it
#13: Re: Mot fail Emissions Author: TattyWater, Posted: Tue Jun 24, 2014 2:43 pm ---- Car is running too rich, hence no air filter = maximum amount of air going in to help weaken mixture.

More air means more fuel. Put the filter in.
