I have already used Fvdi abrites Commander for a long time. But recently I bought a new SVDI the Commander as a substitute when my fvdi is out of work. Before using it for my BMW, what I need to do are to get the BMW function authorization. It's really a hard nut for me to crack. Therefore, I turn to the Aobd2shop (the shop I bought my Svdi) engineer for solution.
And my problem had been treated as priority; I got feedback 1 day after I sent the e-mail to the customer service here listed the instructions on what to get BMW functi On authorization-SVDI diagnostic Tool:
1. Provide the Serial number to the dealer or seller of the SVDI, and let the dealer authorize your device.
2. Start up your svdi, and check their device info to see if the authorization is successfully added.
3. Click updating bottom, and then the authorization would be applied on your SVDI.
Through above 3 steps, your svdi -Commander-is available-work for BMW car.
