Just changed spark plugs on my 09 1.4 Note and now the management light comes on! All I have disconnected is a plug on top of the engine and the 4 coils. I have made sure that no wiring has been trapped on re- assembly (previous post by another member had trouble with this)Engine starts and runs ok, any ideas? btw I don't have a code reader but it looks like I may have to get one. Is the Gendan GCR25 any good?
