- 1) Additionally secures the starter
- 2) Bolt strength class 10.9, steel bolt can be used repeatedly.
- 3) Additionally secures the starter; with additional spacer between the starter and gearbox.
- 4) Use bolts twice.
- 5) Additionally secures the wiring bracket.
Aluminum bolts can be used twice. Therefore, after the first use, mark such bolts with two notches using a cutter "X-arrow-. To avoid damaging the bolts when notching, do not secure them in a vice. Insert the bolt as shown into the 14mm socket using a 1/2-drive, which can then be secured in a vice. Tagged "X" Do not reuse bolts.

Note. Replace bolts that were overtightened. Replace self-locking nuts, lip seals, gaskets and seals. rings. On vehicles with a manual transmission, a needle bearing must be installed in the driven disk. Before installing the disc, make sure that the needle bearing is already installed. Pressing the needle bearing into the driven disk. Hose fittings, air pipes and hoses must be cleaned of oil and grease before installation. To secure all hose connections, use clamps of the appropriate series. To ensure reliable fastening of the air hoses to the fittings, the threaded connections of already used clamps should be treated with a rust remover. During installation, all cable ties should be placed in the same places.
Be sure to clean the threaded holes for fixing the power unit in the cylinder block before assembling the gearbox with a tap. Before connecting the engine and gearbox, carry out the following preparations: Install mounting tool -T40169- from below under the gearbox housing and the dual-mass flywheel, as shown in the figure. The mounting device must fit into the semicircular groove -1- and additionally into the inspection hole -2-.

In order to find the inspection hole, you need to turn the dual-mass flywheel. Insert the bolts of the mounting device into the hole on the gearbox housing. Place the transport protection -T40170- from below under the gearbox housing and attach it to the flange shaft -1-.

Bolt -2- secures the starter to the gearbox and has an additional spacer sleeve -arrow-. The spacer sleeve must be located between the starter and gearbox. If necessary, check the possibility of reusing the aluminum engine mounting bolts on the gearbox and mark them.
Vehicles with manual transmission: Check the presence of engine and gearbox centering sleeves -A- in the cylinder block, insert the sleeves if necessary. Place the gearbox on the engine and tighten bolts -2...5-.
Vehicles with DSG gearbox: Make sure that the mounting bushings -A- are present for aligning the engine and gearbox in the cylinder block; if necessary, insert the missing bushings. Place the gearbox on the engine and tighten bolts -2...5-.

Relieve spindle -10-222 A/11-. Lower the crane and place the engine and gearbox on the engine mounts. Install the engine mount. Remove service tap -VAS 6100- and hanging device -2024 A-. Tighten the remaining engine connecting bolts to the gearbox. Remove transport securing device -T40170- and mounting device -T40169-.
Vehicles with manual transmission: The next step is necessary to ensure that the clutch module is evenly adjacent to the driven disc and does not warp. Install the front wheels. Engage 4th gear and rotate the front wheels in the direction of travel until the clutch module makes a full revolution. The inspection hole -arrow- should again be visible in the recess of the gearbox housing.

Secure the clutch module to the driven disc as follows: Screw in the first bolt -arrow- by hand (2 Nm).
![](https://www.audimanual.ru/img/q/0280.jpg)
Rotate the front wheels in the direction of travel until the clutch module rotates 240°. Tighten the accessible bolt in this position to the specified torque. Rotate the front wheels in the direction of travel so that the clutch module rotates 120°accordingly, and tighten the remaining 2 bolts to the tightening torque.
Vehicles with DSG gearbox: The next step is necessary to ensure that the clutch module rests evenly on the driven disc and does not warp. Lightly press the clutch module -2- using the mounting lever -1- onto the clutch driven plate -3- -in the direction of the arrow-.
