Is my oil pump failing

Maintenance/Repairs

Hi folks! I feel like I already know the answer to this but I also feel like I could be an idiot.
So, I lived in the Benz for a few months. I didn’t drive it but I did run it to charge the battery and use the heater.
Along the way, the oil light started coming on. It was long overdue for a change. It also started “smoking”. White colored exhaust. The oil light would turn off after about 5 minutes.
Anyway, fast forward, changed the oil, got employed and don’t live in it. Now I drive it fairly regularly.
After a couple of weeks of regular driving the smoking stopped entirely. It was always intermittent and only ever happened after the car was warmed up. The oil level is correct and the car runs and sounds great. No water in oil or oil in water. But the oil light still comes on after about 10 minutes of driving. Then goes off about 5 minutes later and doesn’t come on again.
I think it’s the oil sensor and I know it’s a cheap and easy thing to eliminate as the cause but for reasons that would take too long to explain I’d like other opinions. Thanks in advance for your time and help!
