Triple flush differential

Does anyone know in detail what that means when you take it back to the dealer that they want to do a triple flush differential thank you

Triple flush is for the A8 transmission. No reason to do anything more than a simple drain & fill on the differential.

Will that be needed on my soon to be delivered 2019 GS? And at what mileage?

They hook it up to a pump and fill the transmission, lines, and cooler then pump it all out, then fill and empty 2 more times. Tripe flush worked on my 2016 at 15k miles. At 20k now, still good.

Depends on how you use it. Normal Service Schedule says rear axle at 45K. Severe Service Schedule says 45K miles for both A8 and Rear Diff. Track duty drivers diff change to every 24 hours of track use. Might give you an idea how much more stress track duty places on a car Vs even spirited driving on the street.
