Hi - has anyone come across the red engine light on (immobiliser light I think) but starts/runs and drives fine. It is on a 06 defender - the other issues I have with it but don’t know if related are that I can’t get a code reader to link through the odb port (powers up but won’t link) and also the interior light doesn’t work with the doors. Do you think it points to an issue with the 10as? Any ideas or experiences welcome thanks
