MECHATRONIC Circuit Board, Removing And Installing: Removing
-- Remove the DSG Transmission Mechatronic -J743-. Refer to MECHATRONIC, REMOVING AND INSTALLING .
-- Place the Mechatronic on a clean, soft surface.
There is a risk of destroying the transmission control module (Mechatronic) with electrostatic discharge.
- Always "discharge" the static electricity before working with electric connectors. Do this by touching a grounded object, for example vehicle ground, the vehicle or the hoist.
Using an inappropriate tool can damage the transmission control module (Mechatronic).
- The Mechatronic must be replaced if the locking mechanism for the connectors gets damaged while unlocking and disconnecting the connectors.
- Use a screwdriver -a- = maximum 3.5 mm to unlock the connector.
Unlocking the connector
-- Unlock the connectors -1 and 2- on the Mechatronic carefully using a screwdriver -3- in direction of -arrow A- and disconnect them in direction of -arrow B-.
-- Loosen the screws -1, 2 and 3- on the small circuit board -A- approximately 5 mm.
-- Remove the screws -4 and 5- completely and move the wiring guide to the side.
There is a danger of an insufficient contact connection.
- The contact springs on the circuit board can be connected one time only. A circuit board cannot be used again once it has been removed.
-- Pull circuit board 2 just far enough until the contact springs -2- on the circuit board are free from the contacts -1- on the valves.
-- Remove the screws -1, 2 and 3- carefully and remove circuit board 2.
-- Loosen the screws -1 through 5- on the large circuit board -B- approximately 5 mm.

-- Pull circuit board 1 just far enough until the contact springs -2- on the circuit board are free from the contacts -1- on the valves.
-- Remove the screws -1 through 5- completely and remove circuit board 1.
