While not a common problem, this could be caused by a faulty oil pressure sensor. But it’s important to have this checked out by a mechanic because you could be dealing with an engine that really is suffering from low oil pressure. If the latter is the case, you risk doing permanent and catastrophic damage to the engine because the oil pressure is insufficient to fully protect the internal parts of the engine.
The reason you’re seeing the light come on when the engine is idling (and presumably at operating temperature) is because this is when the engine’s oil pressure is at its lowest. When you rev the engine, the oil pump turns faster, creating more oil pressure. When the engine speed drops again, the pump slows, the oil pressure falls and the warning light switches on.
By having the actual oil pressure checked at a workshop with an independent gauge (separate to the one in the car) you’ll know if the light is coming on because of a duff sensor or because the oil pressure really is too low.
There are so few LDVs out there it’s hard to say how reliable they are, but we know the iMax and Carnival are good. I would go for the Carnival.
Your car is still under warranty, so take it back to your dealer and have them fix it.
