3. Remove the DSG (see Section 15).
4. Unscrew the service hole plug (In the illustration 21.11 Chapter 1) next to the rocking support, and then unscrew the overflow tube located behind this plug - approximately 5 liters of working fluid will pour out. Screw in the overflow tube.
5. Unscrew the lid (1 in illustration 21.6 Chapter 1), tilt the filter (3) slightly so that the working fluid flows from it into the DSG, and remove the filter. Install a new sealing ring (2), after lubricating it with DSG fluid.
6. Wet the sealing ring in the receiving sleeve (see illustration 21.7 Chapter 1), install a new filter and tighten its cover with a torque of 20 Nm.
7. Fill the DSG with fresh working fluid (see Section 21 Chapter 1).
8. Remove the clutch cover retaining ring and lift it up with a screwdriver.
9. The clutch cover can be supplied with or without a bushing. Installation of a clutch without a sleeve is described in paragraphs 10-13, and installation of a clutch with a sleeve is described in paragraphs 14-16.
10. Clean the T10302 mounting sleeve and make sure it is free of scratches. Make sure the new clutch cover is dry and there is no grease on the center seal. Clean the end of the clutch shaft if necessary. Only the seal on the outer edge of the cover can be lubricated with DSG working fluid. Place the T10302 bushing on a flat surface.
11. Deform the center seal (In the illustration) new clutch cover (A). To do this, push the cover evenly and horizontally onto the T10302 bushing - the sealing edge is brought to the installation position. Remove the sleeve from the cover in an upward direction and install the sleeve onto the end of the clutch shaft.

16.21. Pulling out the pump drive shaft
22. The details of the supplied clutch are shown in the illustration. The cover of the new clutch is not secured with a retaining ring (5), it is seated in the clutch with a slight tension to prevent the clutch parts from falling during transportation. The cover can be carefully removed before installing the clutch.
16.22. Details of the supplied clutch 1. Clutch; 2. 10 retaining rings of different thickness, with a step of 0.1 mm; 3. Clutch cover, a sleeve is installed to protect the central seal, which should not be removed; 4. Cover retaining ring 3; 5. Cover retaining ring 3, do not install wave rings
23. Remove the new clutch from its packaging, pressing down on its cover to prevent the cover and the backing plate underneath from sliding off the inner plates. Pay attention to the correct position of the four piston rings (And in the illustration), - their joints should not be located on top of each other. Try turning the rings - they should move freely, without jamming.
16.23. Piston rings
24. Make sure the label is present (And in the illustration) on the clutch. If there is no mark, apply it with a marker opposite the tab (B) of the clutch cover. When installing, the cover tab will need to be positioned opposite this mark. If the cover is being installed on a new clutch, remove the retaining ring (1).
16.24. Lid position
25. Carefully remove the clutch cover in the direction of the arrows (see illustration) and put it aside. Do not remove or attempt to lift the plate support, otherwise the plates may rotate. Place the clutch aside so that it does not fall.

28. Select a 2mm thick snap ring from the clutch kit and temporarily install it (see illustration 16.19).
29. Install the MP3-447 or VW387 holder with a plunger indicator on the DSG flange. Press the indicator plunger against the DSG drive shaft (see illustration 16.29a), reset the indicator, lift the clutch to the stop and record the result. Then press the plunger of the indicator against the hub of the large support plate in the gap of the retaining ring (see illustration 16.29b). reset the indicator, lift the clutch to the stop and record the result. Determine the thickness of the required retaining ring. To do this, subtract the first measurement from the second result, add 1.85 mm and round down to 0.1 mm. Remove the temporarily installed 2.0 mm thick snap ring and replace it with a snap ring of the required thickness.
16.29a. Dimension #1
16.29b. Measurement #2
