Awasome Bmw E36 Check Engine Light Reset 2023. Let’s go on with the search. Check for loose or disconnected hoses, wires, or other components in the engine bay.

My local bmw dealer has informed me that my catalytic converter is failing which is why the check engine light is a constant on. I do have a fault code for the o2 sensor, so it should light up when its running aswell. As long as the programming problem has been resolved, it should operate.
