There is none! I found on my A8 after my transmission needed a rebuild, that Audi didn't see the need for one, they say the fluid is a "lifetime" fluid. which is incorrect, the fluid does last a long time but not even close to lifetime of the car. It should be changed every 60,000 miles -ish otherwise it WILL cost you around $3000.
it takes about 16 to 20 hours
