I first noticed that the directional signal warning light went on for the driver's side. When I use the signal it first blinks fast and then the warning light goes out and the signal has the normal sequence. I checked the bulbs and they are fine. This happened several times when I start the car. Now it started on the passenger side.
In addition to this issue, I now see that the low oil warning light goes on for 1-2 minutes when I first start the car and then that goes out. The oil level appears fine.
This is on a 2000 328i
