Reset of Engine light

Me again... Bloody Car my pain in the bum at the moment..

Just wondering out of a little bit of curiosity how you turn the engine management light off or reset it.?
 
when you say engine managment light do you mean the emission light?
if so the only way to get it off is to plug an OBD reader in and clear it, but it will come back on if the problem is still there.

You have had an induction kit on though havent you so it may be that?
