How do you re-set the service reminder?

I posted this in the C5 forum, but had no luck, so I thought I'd post here. I have a 2003 A6 allroad. My husband did my 70,000 mile service himself, rather than taking to the dealer. However, the service reminder message comes on every time I start the car. We do not know how to re-set it. Please tell me I don't have to have the shop re-set it. Can anyone direct me?

Audi A6 2.0 l diesel 2006.Hi how is the service reminder reset? Audi dealer wont do it as they did not service the car.

VAG-COM (VAG 1551/1552) procedure in the front (If not, get one, the best money you will spend - nice birthday or xmas gift ), without VAG-COM on the last page.

Here it is as clear as I can make it:
0. Display reads "Service!" when you first start the car.
1. With the ignition key in the off position, push and hold the right button under the speedometer. This is the button you use to reset the trip odometer also.
2. Turn the ignition key to the on position, but don't start the engine. Keep holding down the right button while you turn the key.
3. Push the left button under the tachometer. Your service light should reset to say something like "Service in 8100 miles."
