hi there i need some help my new engine has fail emissions test here is the read out smells like its running ritch and smokes when its warm

CO 3.54%vol

CO2 12.1%vol

O2 1.04%vol

HC 451ppm vol

\ 0.928

hope this is a easy fix as been told its the cat but donnor car had new one fitted

could be Lambda probe or the temp sender/temp sender wiring. the new cat is it a proper genuine one or a cheapo copy that half the size the skoda one is??

if its a copy take it off and throw it as far as you can and fit the proper one as they are usually rubbish and it has most likely been changed to fix the fault that is still there.

Do you have vagcom?

I would go with along with the lambda probe theory too, however before you go shelling out on a new one there are a few things you can do in vagcom to check if it's working or not by looking at the measuring blocks whislt the engine is running, the other thing worth doing is checking the ignition timing too.

hi there yes it is a s**ty one but not my choice was on the car yes i do have vag com i did get this report up

how do i test with vagcom this and how do i check the timing as well

You've answered your own with the above readout, swap it out for a Different one, the one that on your original 1300 engine is the same lambda probe if you still have it knocking around...

ok will get it back off my mate as he is sticking it in his rapid on 40s

changed the plugs too i think they where the ones in the car from new that mite help me too

will upload pics later

Where do you get those VAGCOM things from, and how much are they?

Would this work? Seems a bit cheap.
