This thread is a sign!
I've noticed in mine today that when I started it up I got the oil warning light. Next time I started it, on the same level ground it was ok, but I pressed the button to see the level and it said 50%, so from low to 50% on the same incline = Renault electrics. I had already decided I would manually check the dipstick before driving it again, but this thread has jogged my memory big time!
PS yours was just low level on the stick. The pressure warning lamp should come on if there is actually any starvation, and it wouldn't cut out at 3500rpm due to low oil level - it would give you a big f**k off tablet and a bill for a full rebuild or new engine.
EDIT: I'm no mechanic so probably best to ignore that entirely
