When unscrewing the clutch module bolts, hold the crankshaft with the adapter "T40058" from turning. During the final turn, rotate the crankshaft only in the direction of engine rotation "arrow".
Unscrew the 6 bolts "arrow" of the clutch module, to do this, turn the crankshaft in 60° increments in the direction of engine rotation.
Unscrew the "arrow" bolt from the ATF line bracket.
Place a rag under the disconnection point to collect the leaking ATF. Unscrew the "arrow" bolts, disconnect the ATF lines from the gearbox and secure them on top.

Equip a lifting table "VAS 6131 A" a set of conductors for Audi "VAS 6131/10", as well as an additional set "VAS 6131/13" as follows. The remaining fasteners remain unchanged. Secure the jig "VAS 6131/13" 7- at the front left of the engine in the threaded hole of the tension element of the poly V-belt with a bolt M8x35 and a washer with an outer diameter of 25 mm, as shown in Fig. Fasten the conductor "VAS 6131/13" 7- on the lifting table.
Remove the conductors "VAS 6131/10" and a universal retainer "VAS 6131/13" 2- in front of the gearbox, as shown in the figure. Turn the right and left lead screws upwards so that the universal lock "VAS 6131/13" 2- fits tightly to the gearbox. Screw the support plates of the fastening elements to the lifting table "VAS6131 A" with a torque of 20 Nm.
Loosen bolts "1" and "2" of the starter. Press the starter away from the gearbox and leave it in the mounting position. Loosen the remaining bolts "3...10" securing the engine to the gearbox. Ignore "Pos. A". Loosen clamp bolts "1" on the side of the "VAS 6131 A" lifting table and move the rear platform with the gearbox back "arrow".
