service engine light is on how can i reset it without taking it to the dealer.

Thank you however i wanted to do it myself. ''''their must be a way of reset.

Is it the maint. reminder light or the 'check engine' light , that indicates a problem? ???? If it's stored trouble codes , all you do is clear it til the problem resurfaces , possibly worse , clearing codes is not fixing......??

thanks, BMW fixed the problem. replaced the 02 censors. all 4 front and back.
