Worn spark plugs
Spark plugs supply the spark to ignite the air/fuel mixture and create an explosion to produce engine power.
But, the worn spark plugs or plug wires will result in a check engine warning.
Damaged catalytic converter
Catalytic converter is a part of the exhaust system that reduces toxic gases and pollutants.
If it is going out, then rotten-egg smell along with the check engine warning found in BMW.
Faulty oxygen sensor
In a BMW, the oxygen sensor measures how much unburned oxygen is in your exhaust.
A faulty oxygen sensor will turn the check engine light while driving the vehicle.

If the gas cap is loose, then the check engine warning light comes on automatically.
