Hello I fitted a decat 2 days ago and after a 10 min drive the engine light came on so reset it then again 10 min later came on again,isn’t the code the top senser that dosent normally have an issue with decats.
It never came on before,and it undone out of the old downpipe fine so I don’t think I broke it,
I’ve checked the plug and that’s fine.
Is my only option to buy a new one

Happened with mine too. You have to get it coded or mapped out.

Yeah but isn’t that the post cat one that flags the light on? I’ve never had it come on so soon after driving though,all my other cars were decatted and the light took like 200 mile to come on
