214 SPI fails MoT on CO emissions

#1 Post by clayts450 » Thu Jul 04, 2019 3:21 pm

K540WRP failed MoT on emissions, on CO : fast idle 0.48% (max 0.30%), second fast idle 0.52% (max 0.30%), natural idle 1.81% (max 0.75%).

Lambda fine (1.02 on fast idle, 1.00 on second fast idle),

Hydrocarbons fine (117 ppm, max 200 on fast idle; 74ppm max 200 on second fast idle).

I suspect the cat is shot and this was what the tester was leaning towards. What do we think ?

Nook it back in Take it for a blast down to motorway and drive it like it's stolen before it retested , if that fail disconnect camcover breather pipe from the cam cover and bock up . First one works for me the engine as to be red hot and second one worked year ago on a 216 that had piston ring trouble. :D

It could also be a problem with the coolant temperature sensor as this can cause K-series with mems to run rich

Cat additive and an Italian tune will get that figure down.

Cabby failed emissions, quick' Italian Tune' to 'warm up the Cat' and it passed ok.
Had a Fiesta that had the same issue, failing emissions several years. Then they started doing emissions test as soon as I took it in after a hard run and it passed. Sitting at idle while they poked about underneath just let the Cat lose its efficiency.

Agreed, if I get up early enough tomorrow, I'm gonna lob a few litres of Shell petrol and some Cataclean in there for good measure, and then give it a razz down the M1 in 3rd/4th for a junction or two, before rocking up at the test centre.

Yup, NIL.

The tester said to me 'yeah, it's just squeaked past'. I asked him what the readings were and he smiled and showed me.

HCs were 29 so it was definitely working.

I suppose when you combine new barely used cat, 15 litres of petrol, a bottle of Cataclean and an Italian tune up it is entirely possible !

Craig - do you have T4 ? I might need your services with this one. Er, and possibly a new clutch.

Thanks, much appreciated - I'll ping you a PM shortly.

It'll probably be a few weeks before I can come to yours (214 being willing of course !) as I'm booked up for the next two weeks with work, parts collections for various members of my fleet and the Festival of the Unexceptional !
