i will be honest with you. I had this problem before on a unit and i did this:Yes I have tried. When car goes to sleep my phone disappear and the phones previously connected (from the previous owner) come back.
i will be honest with you. I had this problem before on a unit and i did this:
1. HU_SPECIAL_NBTEVO_REPAIR_NAND from DEV_UDS
2. steuern_routeine - STEUERN_BT_DELETE_ALL_PHONE_ID - reboot HU
3. recreate NBTevo system directories from SSH - Reboot HU
4. Try again.
P.S. i also flash it but don;t think flashing will solve it.
No. You need to ensure power supply in Quadlock is on KL 30B which is permanent 12V from battery and not KL.30F which gets disconnected when car goes to sleep.A little update. I think the emulator have something to do with my problem. When connecting bluetooth device the headunit shows BMWXXXXXX where xxxxxx is last six digits from fsc donor VIN. After 7-8 minutes the errors appear in ista. When errors appear and if I try to connect new bluetooth device the headunit shows BMW999999 not the FSC donor VIN. When this happens I check FSC status and they are all rejected but no matter that navi and carplay are working. If I leave the car go to sleep or unplug the emulator for 5-6 seconds the FSC donor VIN returns, all the FSC codes are accepted again and if I reconnect the phone carplay works too. So what do you think? Could it be defective emulator?
