How to Reset oil service light on a 2005 BMW 530I?

This is for Push Button Start E60 models only..... Put 'key' unit in ignition. Leave car in gear and push the Push to Start Button ONCE. Don't worry, car will not start. This is called position 15. All dash lights will light. Now push and hold the Odometer reset button. It will initially light up a warning Triangle, continue to hold until the Oil can symbol lights up. The oil lamp is the first of the service lights to illuminate. They can all be reset by pressing in short bursts. But for the oil reset, when the oil can illuminates, let go, then press and hold. After about 3 seconds a message saying Reset? will appear. When it does, let go the button and press and again until the mileage indicator resets itself. Repeat as necessary for each of the required service indicators. These mimick the iDrive service menu settings, in order, incidentally. Hope this helps..... Aidan.
