Emissions waning light.

[Corby G]

Evening all.

Emissions warning light came on tonight after a short spirited drive, I think I need a new lambda sensor. Just to mention the cars de-catted as well.

Exhausts are not really a strong point of mine so I do apologize for sounding like a useless tw*t.

Does this mess with the fueling at all or does it depend on whether it's pre de-cat or post de-cat?

Cheers

Hi Corby, it's just because it's decatted mate, the lambda sensors are both fine, nothing to worrry about

Hi Tom,

Mother in law took to it a garage this morning just to check it out, they've just overriden it on the diagnostics. Shouldn't come on again hopefully.

It will come on again, might take a couple of hundred miles but it will be back.

if its decatted itll be the down stream lambda sensor causing the light to come on. like above itll most likely come back on at some point.
