Audi say this is sealed for life I believe? I was thinking of buying this http://www.wavetrac.eu/Motul-Multi-DCTF-1-iter And doing it myself to my s-tronic box. Which is on 62k now and if sealed for life will never have been changed. My gearbox changes are super smooth except downshifting manually which can make some shunting noises sometimes, also when coming up to roundabouts in either D or M sometimes when you need to stop then immediately go the gearbox has a hissy fit and you find yourself stuck in the transition period as it figures out what you are trying to do...then finally figures out and catapults you forward a few seconds late... has made for some almost brown seat moments. None of my other cars did this but they were not 8P3's they were 8P2's with different engines and presumably different gearboxes. Car is still under warranty for another 10 months though but I believe they won't change gearbox oil at Audi? When they sold me the car they mentioned the warranty for example if the gearbox goes they will pay towards it...but at an Audi dealer you are looking at half the cost of the car to change gearbox!!! So preventative maintenance makes sense to me? In a year or two I am planning on making it a sleeper, so K04-064, LSD, sticky tyres, supporting mods, 380hp FWD in a A3 Sport will be quite the sleeper!
