Complimentary AdBlue® refill service applies to the cost of parts and labor at authorized Audi dealerships for all 2016 MY Audi TDI® vehicles and 2015 MY A3 Sedan TDI® vehicles. Owners choosing to refill AdBlue® themselves are not eligible for reimbursement. Complimentary AdBlue® refill service applies for 4 years or 50,000 miles, whichever occurs first, and is transferable to subsequent owners. Complimentary AdBlue® refill service applies only in cases where the instrument panel warning light appears at 1,500 miles before empty or at subsequent mileage warnings, provided the vehicle has not reached its specified maintenance interval. In that case, the AdBlue® refill is a customer expense along with other maintenance, except at the initial 10,000-mile service interval or for customers who have an Audi Care plan. See your Audi dealer for details.
