Hi all
Just took the car for mot & it failed on broken rear spring & emissions.
If anyone can give me any advice or information on how to sort the emissions I would be greatful.
Thanks in advance.

Is the car running ok??

Yeah seems to be,think the breathers need cleaning tho.

First thing I was going to suggest (breathers and ICV clean). Maybe an engine flush/oil change wouldn't go amiss. How badly did it fail on emissions? Cat ok?

Cat passed ok,the emissions were both on 2nd fast idle.Not sure of the readings

Might be worth getting hold of a gas analyser which you can get fairly cheap from halfords and the like. I'd clean the whole throttle body assembly as well as breathers and ICV, pay particular attention to the jet at the top of the inlet manifold you'll probably find it is completely blocked.

I get nervous under a bonnet lol i'm a bit limited on tools & worry i'll bo!!ox it up ! i bet a garage would charge a small fortune.

Seriously, it's a doddle even for a beginner. Here's a couple of guides on how to do it. It really isn't difficult, any socket set will be good enough and you may need a couple of torx as well which you can find from halfords or a factors.
Have a read through these...

You should have got an emissions test report with the refusal. Post it up and it might shed some light on why it failed.

I'll have a gander at them & see whats involved.Hopefully I can sort it without spending megabucks!

On the sheet its got fast idle test its got fail next to lambda. its the only place on there with a fail reading next to figures.According to sheet my reading at lambda was 1.04 the max being 1.03.
Hope that helps !

If its not been serviced recently I would do that (oil/filter change, air filter, fuel filter, plugs) and the breather clean previously mentioned.
None of that is difficult esp. as you have a 4 pot.

OK. Sounds like the cat is fine, as you say. Is there any possibility of an air leak into the exhaust system? Manifold gasket perhaps? Any trouble codes stored in the engine ECU? Could be a lazy Lambda sensor perhaps?
I would be inclined to try cleaning out the breathers, etc. as said, give it a service and a quick "Italian tune-up" on the way to the re-test wouldn't hurt.

i know theres an advisory for a slight blow in back box but other than that i dont know.
just had a look at whats where under the bonnet for doing the breathers & cos i'm so short i'm struggling to see whats where !
