Answer
Kevin, have some one who is car literate or use your owners manual to check the oil level of the engine. If the oil level is correct (between the two hashes) then the yellow oil level warning light is comming on erroniously. Most often a fault oil level sensor at the bottom of the oil pan. A BMW shop can verify this by checking the fault codes stored in the engine computer. Replace the oil level sensor and perform oil and filter change. Front windshield at our U.S. dealer for your car cost about $550.00 USD.
