No changes . Original key and chip. Just tried to reprogram it with My "My Naff Code Reader". In immo live data shows that key is ok, signal transmitted, signal correct and so on. Like i said, just one thing… Request from engine - not received.. i tried different ecu ant immo just to look if it gets engine request,but nothing.. same issue.. i think there is maybe problem with wires, but im not professional eletric, so i dont know everything how to check correctly. I cant even find diagrams , maybe then it gonna be easier somehow
