How to read BCM2 from VAG vehicles?
Since FVDI doesn't have ABPROG, so, you can't use Abrites V18 or V21 software to read the BCM2 from VAG Vehicles.
However, you can turn to use IMMPPLUS software, it will help you read the BCM2 and no need use ABPROG.
First open VAG Commander, then Open IMMOPLUS software, if the software tell you Can't find Device (Programmer), you just unplug FVDI USB cable and plug it again to your PC, now open IMMOPLUS software, it will find device (Porgrammer).
If all keys are lost, you can just direct read the BCM2 from OBD.
