When is the timing belt due?

When should I change the timing belt on a 2009 (59) Audi A6 2.0TDIe, when the service book says 114,000 miles? My dealer says 75,000 miles. It is after-all still under warranty, so if it snapped wouldn't Audi be liable?
Needs doing now. Waterpump as well. Isn't the warranty mileage limited?
