Oil Function
Oil does not just lubricate the transmission.
The oil also transports the finest differential abrasive parts in both filters. The oil makes sure the lubricating film does not wear off the differential tooth flanks. At the same time, it acts as a switch valve pressure medium to enable it to perform its functions.
It also seals the selector lever and helps the synchronizer rings when shifting gears. The oil conserves and transports warmth and minimizes noise. The fluid performs many functions. The DSG oil meets very high demands!
To maintain this degree of performance, the filter on the transmission should be replaced during the oil maintenance service.
