Hello all!

I’ve been fighting this issue for over two weeks and finally decided to ask for help from the BMW community; maybe someone already had a similar problem.

Long story short.

Driver profile settings (radio volume, treble, bass, audio source, and added Bluetooth devices) are not saved in the active personal profile when you leave the car, lock it and let it sleep; the next time you return and turn the HU, all the settings are reverted to the previous save (some time ago).

What I have tried:

- Deleted Private Data
- Exported and imported the driver profile to/from USB; it’s working until next sleep/start
- Flashed the HU, FEM and KOMBO to the latest I-level
- Coded HU with the default setting
- Replaced the HU-B with the same unit but from F45
- Replaced the car battery
- Replaced the key battery
- I have only one car key, and I am unable to check with the other key

No errors within ISTA+

My car is F22 m240i, 2018 with HU-B – ID6

What else can be checked? Please advise!

Did it used to work? If so did you make any changes before it stopped?

Also are you sure the other key is not lost in the car somewhere?

It was working fine before, but I didn't adjust the Treble / Bass for some time, and I only found it not working when I changed my phone from Android to iPhone, adding it to the car, and it stopped remembering it in the Bluetooth devices list.

As for the key, it seems that it's lost, but not in the car.

Does someone know how the process works, saving settings in the Personal Profile for the volume, Treble, and Bass? I'm just wondering: could someone tell me where the Personal Profile is stored?

P.S. All other vehicle settings are saved without issues; only Volume, Treble, Bass, and Bluetooth devices are affected. For example, once you set them up, BMW memory buttons will all work fine at the next start, and mirror memory will not be affected.
