NOTE: Do NOT activate the MaxxECU Default V1.3 CAN output on the same bus as the DSG, cause it will interfere with the control operation and cause trans going to neutral and random strange issues.

NOTE: PDM20 uses the 0x50 CAN message ID for communication, which might be available on some Audi (equipped with airbag modules), do NOT use on the same bus!

* It seems that some DQ200 have the same hardware number but we never tested them, please be careful as we cannot assure you that the DQ200 will work with our VAG DSG CAN protocol.

Note: It might work with other TCU numbers also, if you are having problems with a specific number, or want to report a successful DSG control, please contact us.
