Title: MOT Failure - Emissions
Post by: toller on 26 November 2010, 13:02:18
Just had the car in for it's MOT and one of the things it's failed on is emissions, specifically the CO content.  On the fast idle it was 0.49% against a limit of 0.3% and on the second fast idle it was 0.36% so was only just over.

Of all the things it can fail on it's the emissions I hate the most as i've no way of checking them myself. 

Anyone got any suggestions as to what I can do to get them down?  I'll be giving it a thrashing up the motorway before i take it in for the retest but anything else that could help would be welcome.

It's also been failed on the parking brake having no reserve travel even though it is fully on within 5 clicks which I'm a bit confused about.

Give her a damn good thrashing, get her nice and hot, and as for the hand brake, just take up the slack slightly on the ajuster, I think the tester is just trying to find things which arnt wrong personally, they can be arsey sometimes >:( >:(

oil and filter change could help, as could air filter change, make sure car is fully warm when taking it for retest

Check it has the return springs on the rear lower side of the shite guards behind the rear discs.

Any leaks on the zorst system? That can raise the CO levels. As already said, new air filter, oil filter and oil. Get it nice and hot and get it re-tested :y

P.S. Ask your MOT place if they'll do the emissions first, that way you won't have to go through the whole re-test if it fails again.

I've already bought some cataclean so that'll be going in as soon as it comes.  I don't really use the car that much as i prefer motorbikes (even in the winter) and when i do use the car it is only for fairly short journeys.

My previous omega failed on emissions a few years ago and a good thrash up the motorway got it through ok although one of the cats failed about 2 weeks later.

Not checked on the return spring on the handbrake but i'm going to have a look at everything this afternoon.  Still -5 outside too so it should be fun :)
