My check engine light is on in in my BMW 2010 X5 - it came

Customer Question

My check engine light is on in in my BMW 2010 X5 - it came on with an error saying the gas cap was not locked. I locked the gas cap, my mechanic reset the light and a few days later the same thing happened - same error and light came back on. I've now
replaced the gas cap and had the light reset and after 2 days the same error came on the dash screen and the check engine light came back on. Could it be a faulty sensor? how can I check that? Thanks.
