I haven't seen one done by anyone on here so I am adding mine. Hope it helps someone.
I decided to do a technical write up on the service you should be doing every 40K miles.
The transmission has to be cold at start of service in order to adjust fluid level properly. I'd let the car sit overnight so that it gives you time to do what you need to do.
Parts you'll need
6x 1L of DSG Oil OE# G 052 182 A2 $18.34/1L
DSG Oil Filter OE# 02E 305 051 C $43.22
Tools you'll Need
Ross Tech HEX-CAN cable and computer
14MM Allen socket (for drain plug)
24MM Hex Socket (for filter)
8MM Allen Socket (for overflow tube)
T20 Torx (for airbox inlet)
I have this tool
AST 1000 Fluid system
AST ATF 106
First you'll need to remove the upper engine cover/airfilter
It is difficult to remove this cover because of the way it is held on. I pull up in the back first as it is reinforced. Remove MAF connector, clips for turbo inlet and fresh air inlet. Watch out for J nuts on the airbox inlet, if they come out put them back on the way they came off.
Next you'll want to remove the filter housing. It is located under the battery and is hard to see at first. Use a 24MM socket with extension to loosen the housing. Reach down and unscrew the housing and tilt it in it's bore to drain the fluid back into the trans. Once it is done draining pull housing out from behind the engine. It is a tight fit and requires patience. Pull filter out same direction. Replace filter in opposite order. The filters do not come with O-rings so reuse old one. I's assume at some point there will be one included with the filter but for now it is okay to reuse. After the filter has been replaced, install engine cover and reconnect MAF harness and clips and torx screws.
Next you are going to go under the car. With the car properly raised off ground using suitable jackstands or ramps, remove drain plug using 14MM Allen socket. Use a container able to hold approximately 6L of fluid. Once the plug is removed you will notice that not much fluid comes out. Once the initial fluid stops you can use an 8MM Allen or Allen socket to remove the plastic overflow tube inside the drain hole. This is where you will drain 5L of fluid.
Once the fluid has stopped draining replace plastic overflow tube and tighten to 3 nm.
Next you will be inserting VAS 6262 Tool or AST ATF 106 tool in place of drain plug.
The VAS 6262 utilizes the DSG fluid bottles to fill the transmission. It is more time consuming to do it this way but should be cheaper than purchasing the AST system. However if you are doing alot of trans services it pays for itself fast. From this point on I will be talking only about the AST system.
You will now need to fill the AST bottle with the DSG fluid. It holds about 3.5L of oil so you will need to refill before the engine is started.
Now connect the AST hose to the fitting you previously inserted into the drain hole.
Connect VAG-COM to vehicle and access transmission electronics. Go to Data block 19 and monitor Transmission Fluid Temp.
Pump 5.5L of fluid into the transmission and close off valve. Go to the topside of the car and start engine. Holding brake, move gear selector into each position for 3 seconds and return to park. Now let idle and watch temp on screen. Once the temp is at 35 deg Celcius, remove adapter, hose and allow excess fluid to drain. Once the fluid level is correct it will slow to a drip. At this point replace drain plug with new aluminum washer and torque to 45 nm. Clean off oil and test drive. Enjoy!
