Hi all i thought this would be a good place to start with my problem , here we go , i have a 2010 Audi A3 1.6 Tdi SE 5 door with the 7 speed dsg gearbox which i have owned from new , 2 years ago the dsg gearbox was replaced under warranty due to swarf in it , everything thing was fine until until under a recall the gearbox oil was replaced with mineral oil , now it hangs on to the gears to long in auto mode until it gets warmed up (i am talking in to the redline to long ) i want to change it back to semi or fully synthetic oil but cannot find any spec on witch oil to use , i know that the 6 and 7 speed take different oil , can anybody help ?
