Check Engine light

Hey All,
Any quick hints on diagnosing the red 'idiot light' at the far-right side that happens to say Check Engine?
My blue MB manual says something boring about an O2 sensor being out, or some such silly thing...
The car drives fine...I hope it's not about to explode??? [;)]

I don’t have a “check engine� light, it actually says “O2 sensor� where I’m guessing the check engine light is on your car. [?]

I wonder what it means if it doesn't light at all (when you turn the key to Accesory/power, but not crank it)? And i swapped the bulbs already with a good one. It used to work fine, but it just stopped working sometime ago.
