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!
