Check engine light

I have a 97 528i and the engine light came on. Does anyone have any suggestions about what the problem could be. Can you reset the light by disconnecting the battery or does this cause problems. Any info appreciated

if u gonna disconect the battery you'r radio may get locked, just go to AUTO ZONE they gonna check what's wrong and they can erase it for free.

I will do that first thing Monday morning, thanks for the direction
