Post Title: DSG Fluid and Filter Technical Write-UpPosted by: Sureguy at 8:24 PM 8-20-2008

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 itgives you time to do what you need to do.

Parts you'll need

6x 1L of DSG Oil OE# G 052 182 A2 $18.34/1LDSG Oil Filter OE# 02E 305 051 C $43.22

Tools you'll Need

Ross Tech HEX-CAN cable and computer14MM Allen socket (for drain plug)24MM Hex Socket (for filter)8MM Allen Socket (for overflow tube)T20 Torx (for airbox inlet)

VAS 6262

or

I have this tool AST 1000 Fluid system

withAST 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 MAFconnector, clips for turbo inlet and fresh air inlet. Watch out for J nuts on the airbox inlet, if they come out put them back onthe 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 socketwith extension to loosen the housing. Reach down and unscrew the housing and tilt it in it's bore to drain the fluid back intothe trans. Once it is done draining pull housing out from behind the engine. It is a tight fit and requires patience. Pull filter outsame direction. Replace filter in opposite order. The filters do not come with O-rings so reuse old one. I's assume at somepoint there will be one included with the filter but for now it is okay to reuse. After the filter has been replaced, install enginecover 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, removedrain plug using 14MM Allen socket. Use a container able to hold approximately 6L of fluid. Once the plug is removed you willnotice that not much fluid comes out. Once the initial fluid stops you can use an 8MM Allen or Allen socket to remove theplastic 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 becheaper than purchasing the AST system. However if you are doing alot of trans services it pays for itself fast. From this pointon 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 engineis 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 tempis 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!

Of course if you don't want to buy the tool you can always make one. http://deviantspeed.com/diy-ds...s6262

You should also make sure that when you are doing the final step. To have the car level so the right amount of fluid comesout. This will let you make sure its filled to the proper level and not a little less because the car being on a slope.

To the OP, this is an important step which according to the photos was not followed!

Good point. If you use a set of ramps the trans actually sits pretty level. Otherwise a rack is preferred.

Can this get added to the DYI Trans section?

Nice work

Post Title: AHHHHPosted by: linux_guy at 5:23 PM 8-22-2008

I wish I could do it. Besides dealer ships who can do this properly? I assume this is not regular shop kind of stuff?

And how much is this at the stealerships?

Post Title: Re: AHHHH (linux_guy)Posted by: Sureguy at 6:17 PM 8-22-2008

It's really not that hard. The biggest hurdle you have to get over is that it is not filled from the top. Once you canconceptualize how the service works it's cake. If you've done one you can do it within 30 min again with the right tools.

yeah looks good even from just that small preview

anyway back on topic, my bad

Post Title: Posted by: Speeddemon69 at 5:05 AM 2-5-2009

what do you guys mean by leveled? like the car has to be on a lift or on 4 jack stands? also how does the fluid go in if you doit one quart at a time with the other hose?

Post Title: Re: (Speeddemon69)Posted by: Tim Birney at 6:17 AM 2-5-2009

Normally the fluid is gravity fed (think of an IV setup as seen in Hospitals).The pump in this write-up is pricey, so I went to Murray's Auto and purchased a $6.50 Valvoline hand pump.The threads on this pump don't work on the DSG bottles, but it doesn't matter.There is an extension tube on the Valvoline pump that can be trimmed for length. Just attach it to the pump, trim the lengthuntil the top of the pump touches the top of the bottle, and hold it in place with one hand, and pump with the other.

Is this like a gear lube pump for filling differentials?

I bought the ATF 106 adapter and was thinking about using a bug sprayer to pump in the fluid, but I guess a gear lube pump

would work well.

so you are letting the car run after removing the adapter(while letting the excess to drain?
