Changed my DSG fluid\filter in my 2009 Sportwagon this weekend. I agree with the other 09 owners, the battery and battery tray must come out in the 09s to access the filter. This seems to be optional on the 06s. If you do pull the battery, make sure the radio, lights and all the windows\sunroofs are off\closed.
I drained about 4.5L used fluid from mine. I filled with 6L (needlessly) and 1.7L excess came out after heating to 113 farenheit (verified VagCom with contact thermoter after drain). I was on the high side of fluid temperature so a little more then I would have liked drained off, however, I'm sticking with it as I'm only .3 L short compared to what was originally in there. I'll be keeping an eye on it.
Because I disconnected the battery to get at my filter, my JSW also threw the "Electro-Mechanical power steering assist reduced" error. I also got the Traction Control indicator. On p.240 of my manual explaining the power steering, it states "if the battery has been disconnected, the yellow indicator light comes on after the ignition is switched on. It must go out after driving a short distance." I drove 1/2 block and both warning lights disappeared. The rest of my test drive went great. I DID NOT reset my DSG settings back to basic and she shifted just like she has in the past (pretty well).
Due to difference in reports for tools necessary, i didnt have all the tools necessary and had to go to the store multiple times for the proper tools. To that end, I thought I'd post what was needed for my 2009 JSW. Hope it helps someone...
-24mm socket (DSG filter canister)
-14mm Hex (DSG drain\inspection plug)
-8mm Hex (snorkel)
-7mm Hex (air filter housing removal)
-T25\T30 torx (plastic undercarriage pan)
-10mm socket (battery tray)
-7mm? socket (battery terminal)
-Torque wrench(s) (I used two, a small one for snorkel and a larger one for the other required torques)
-homemade VAS6262 (3/8 id hose, filled from beneath in less then 10 min with two people)
-VagCom or non-contact thermometer to measure DSG fluid temp
-Oil drain pan
Good luck to anyone doing this. I would definitely plan on having a helper around. It was helpful for me when filling my homemade VAS6262 to keep fluid consistantly flowing without introducing air between pours into the funnel.
I'd be happy to help anyone in my area accomplish this maintenance. I was kinda leary of doing this but was not going to pay the dealer $1,100 + to do my 40K. Come on! $1,100! Ridiculous!
