I've been wanting to address a few minor annoyances with my wife's 2016 BMW 328i (F30). Specifically, the audio stays on when the car is off and doors are opened and not having full Enhanced Bluetooth functionality. I figured I'd get the vLink tool, some software & watch a few videos to figure it out.

It's a little Bluetooth device that plugs into the OBD2 port. I tried pairing it with my phone a few times and didn't have any luck. Eventually I figured out that Bluetooth to the car had to be disconnected from the phone so that the vLink was the only active, paired device. After pairing was successful, I downloaded & installed the Bimmercode app. The app asks the device being used to connect to the car & the type of car itself. Once all that was configured, the device & software worked flawlessly during the ECU update process.

I was able to successfully complete the updates and now those few minor annoyances have been resolved. I have to explore the other software options available to view codes, statistics, etc. The vLink device will definitely help you to achieve your BMW upgrade/modification goals.
