I think I would be looking for the oil pressure switch. It's probably not as simple as that now but something must sense the pressure and switch the light off or on as required. A temporary gauge connected to the tapping would remove all doubt. It's been like that for 100 years but probably something ridiculously complicated now.

A simple pressure switch is still used.

Have you changed the oil filter recently? 2018 SE SDV8 4.4 Byron Blue |

Oh yes, must check that plug with every filter change. |

Mine does this when parked on a slope facing up. Never on the flat or facing down. Never got to the bottom of it but suspect something to do with how the oil pickup in the sump is situated. It’s definitely oil starvation as the engine noise changes when the light goes out. I always try to park facing down. 2012 TDV8 Vogue (L322) |
