I was curious if anyone had a suggestion in regards to resetting the check engine light on a 2002 E430.

I live about 300 miles from the closest dealership, so I may have to drive around with the light lit. There's no fault that I can find with the car and I may have resolved the issue that made the light come on when I filled it up.

I've read other responses regarding AutoZone being able to reset the light; our local AutoZone does not reset the light.

However, they did provided a suggestion; I was told that by momentarily disconnecting the + (positive) side of the battery, that would reset the light. Anyone know how true could this be or provide any other suggestion?
