Gentlemen, I drive a manual 1997 BMW 318i which has 150,000 miles on its odometer. Lately and not every day, the ‘check engine’ light on the dashboard lights up. It’s a steady light, and it does not flicker. The car runs and operates smoothly. Mostly it occurs on wet and rainly days. Has humidity something to do with it?

How concerned should I be, and am I endangering the motor?

I would greatly appreciate your advice, and I thank you in advance.
