Mein Auto: 2000 M5
There's a multitude of reasons why a check engine light can be triggered, not only in the E39 M5 but in many other makes and models. It can be as simple as the gas cap not being tightened, or as complex as a failed exhaust sensor. The check engine light on my 2000 E39 M5 has come on after the two most recent gas fill-ups, after the gauge has dropped to about 3/4 full, and then the light has gone out after the gauge drops a little further. I plan to ignore it, unless it goes on at some point and won't go off.
