I change an ECU on a Golf 4 1.6 with BFQ engine. Everything work fine but the problem is that The ECU was from an Automatic model.
I get emission warning and the ecu have no communication with Automatic control unit error.

My ECU is 6Q0 906 033 BL Is been a long time since I change the ECU so I can't find the old one.

Is it possible to change the Coding with any way? MY code is 0033 and I need 0031

Thanks in advance

This ECU is for automatic transmission that's why it doesn't except the coding. so I believe the only solution if is possible is the reprogramming.
