When Craig discovered his local BMW dealer charges $50 to reset the oil change indicator light on his 1999 BMW 528i, he did what any good engineer would do: He built his own reset tool. The simple, money-saving tool is essentially a wire with a pin on one end, a clip on the other, and a resistor in the middle. He simply attaches the clip to a proper ground point in the engine compartment and inserts the pin into the diagnostic or data link connectors and voila—lights out!
