DSG swap

Connector references and essential wiring pinouts for DQ200 and DQ250 transmission swaps.

Before wiring

Disconnect the battery before changing the harness. Confirm the connector orientation and pin numbering on the housing, then verify every circuit against the wiring diagram for the donor transmission and target vehicle before applying power.

Using a donor DQ250 MQB (0D9) mechatronic or transmission for a DSG swap? See the DQ250 MQB immobilizer removal and bench flash guide before installing the replacement TCU.

Terminal reference

Terminal 30 — permanent battery positive

Terminal 31 — ground

Terminal 15 — ignition-switched battery positive

CAN High and CAN Low must remain a correctly routed twisted pair. Do not rely on wire colour alone when identifying a circuit.
