Why when starting my 316i e46 does the oil light come on

This answer was rated:

why when starting my 316i e46 does the oil light come on again after about 15 seconds and then remain on for a further 30 seconds is this normal or is it something to do with the engine management system or is it pressure build up in the crankcase

Hi Howard, my name is***** the oil light warning red or yellow?

Ok, that is your low oil level warning. If the oil level is correct it would indicate that the oil level sensor is not reading accurately. Replacing the sensor should solve the problem or you can ignore the warning.

The sensor is located in the bottom of the oil pan. It is easily replaceable. If you post the last 7 digits of your vin number I can look up the part number for you.
