If I'm 100% wrong and 180 degrees backwards on this, then you're right that a broken wire would be illuminating your light. Somebody correct me on this if I got it backwards.
The 1 minute delay is likely the fact that the thing is configured to wait 1 minute after the switch says "low oil" before illuminating the light to compensate for the fact that the oil may sling away from the sensor every time you turn right or left (whichever it is) and you don't want the light flickering constantly.
Either way it's probably a wire problem. But disconnecting *I THINK* will simply result in never getting an oil warning.

I'm not certain, but that is not how this system appears to work. The FSM mentions that the Oil Level Sensor is connected to the IFI Control Module (N3/7) which communicates the signal to the multifunction display viw the CAN bus. Not as simple as I would perfer. There are at least two possibilities: 0 volts or 5 volts as far as I've been able to tell. I will double check the function of the old sensor and let you know how this works.
