I have an oil light on my Range Rover sport 2007. The light has been on for over a year and I have driven the car during that time. I have been told that this could be a oil pump failure. Most of the posts I read say that when the pump fails it affects the running of the car immediately but as I’ve said the car runs well. Could it be something else like a faulty oil pressure switch?

No unknown
Probably faulty dash. (Soldering issue)
