Genuine Audi 8HP65A/AL552-8Q transfer case/center differential gear oil.
One 1L bottle is enough for one service. The fill capacity of the transfer case/center differential is 1L.
Service Interval
Audi technically does not list a service interval for the transfer case/center differential gear fluid in the AL552-8Q transmission. However, since gear lubricant does eventually wear out, it should be changed. We recommend changing it every 40k miles for the best results.
