I drive a 2003 r50 and I just got my oil change two days ago. For some reason my oil light comes on when my car warms up and when I am idling. When the oil is cold like in the morning, the light does not come on. However, when the oil is warmed up, the light would come on every time I'm at a stop. Does anyone know what the problem might be? I took it to the shop I got my oil change and they said it wasn't from the oil change they did but it possibly might be the oil pump or sensor. I have never had this problem until my recent oil change 2 days ago. My car has about 89,000 miles, with 5w30 synthetic oil.

There is no leaks and when I checked today in the morning when I turned on my car to warm it up, the oil seemed to be at the right level.

The store said they'll charge me $90 just to diagnose it. Does anyone know how I would be able to check this myself or am I just out of luck? One of my friends told me that every time I get an oil change, I have to reset the sensor or something like that for the car; however is that true?

If anyone has any suggestions or has been through the same problem, please let me know ASAP. Thank you.
