Removing

  WARNING

The system is under pressure.

• The electronic ATF pump must be deactivated every time before opening the transmission, and the hydraulic pressure reservoir is drained.
• Refer to → Chapter "ATF Pump, Deactivating and Draining the Hydraulic Pump Reservoir".

  Note

• General repair instructions. Refer to → Chapter "Repair Information".
• Guidelines for clean working conditions when working on the dual-clutch transmission. Refer to → Chapter "Rules for Cleanliness When Working on DSG Transmission".
• Disable the ATF pump and drain the pressure reservoir. Refer to → Chapter "ATF Pump, Deactivating and Draining the Hydraulic Pump Reservoir".

  Caution

Risk of destroying Transmission Control Module -J217- with static discharge.

• Always "discharge" the static electricity before working with connectors. Do this by touching a grounded object, for example vehicle ground, the heater or the hoist.
• Do not touch connector terminals in the transmission connector with hands.

- Remove the transmission fluid pan. Refer to → Chapter "Transmission Fluid Pan, Removing and Installing".

- Release the connector for the Hydraulic Pressure Sensor 1 - G545--1- and Hydraulic Pressure Sensor 2 -G546--2- at the retaining tabs -arrows- and disconnect from the Transmission Control Module -J217-.

- Secure the connector as shown in the designated transportation safeguard.

- Remove the Mechatronic. Refer to → Chapter "Mechatronic, Removing and Installing".

  Caution

Contamination damages the Mechatronic.

A clean work environment is required for working on the Mechatronic.

- Release the cover -1- for the sensor from the retaining tabs -arrows- and remove.

- Remove the bolts in the sequence -3 to 1-.

- Pivot the Transmission Fluid Auxiliary Hydraulic Pump Rotor Position Sensor -G847--1- to the side to the engagement position.

- Engage the connector for the Gear Position Distance Sensor 1 -G487- and Gear Position Distance Sensor 2 -G488- in the transportation safeguard -arrow- and loosen the bolts in the sequence -4 to 1-.

- Remove the Transmission Control Module -J217- from the valve body.

Installing

Install in the reverse order of removal while noting the following:

  Note

Before installing clean the control module threaded holes of oil and debris.

- Push the control module evenly on the valve body and tighten the bolts in the sequence -1 to 4- to the tightening specification.

  Note

• A protector -1- is located on the ATF pump.

• Pay attention to the correct assembly.

- Push in the sensor arm -1- on the ATF pump -2- by hand and tighten the bolts -arrows- hand-tight.

  Caution

There is a risk of damaging the ATF pump.

The sensor arm -1- must make contact when attaching the ATF pump -2-.

- Tighten the bolts to the specification in the following sequence: -1 through 3-.

- Install the cover -1- for the sensor arm -arrows-.

- Install the Hydraulic Pressure Sensor 1 -G545- and Hydraulic Pressure Sensor 2 -G546-.

  Note

• The connectors must not be interchanged.
• Make sure that the connection is correct as shown -1 and 2-.
• Refer to → Chapter "Hydraulic Pressure Sensor 1 -G545- and Hydraulic Pressure Sensor 2 -G546-, Removing and Installing".

- Install the Mechatronic. Refer to → Chapter "Mechatronic, Removing and Installing".
