How can I reset service on my bmw 525e

SOURCE: BMW 5 series - 2005 model - resetting service & waring lights

the brake pad warning light is controlled by a sensor located in the front and rear brake pads, small contact with 2 wires that plud into a harness, if they are bad I think the replacement cost is around 5-10 dollars for a new one, there will only be one in the front and one in the rear, the service light is turned out by a special tool at the dealer

BMW requires a scan tool to reset the light.

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door
