Hi everyone

I've managed to wire/install heated seats on my stock A3 8v 2015 using kufatec loom, but I've got an issue with Terminal 30 open circuit with which I believe new BCM that support heated seats is needed since pin 1 is missing in connector A which provides power .

The part number for the required BCM is 5Q0937084AS, now the question is can I copy / past my current BCM coding/adaptation into the new one (which will be a used unit) or will it need coding via odis?

Any help will be much appreciated.
