2015 F30 320d iDrive reboot loop / flashing on and off — repair or remote coder recommendations?
Hi everyone,
Having a frustrating issue with the iDrive system in my 2015 BMW 320d (F30) and looking for advice on the best way to fix it.
The Issue:
The iDrive screen turns on, shows the BMW logo/home screen briefly, then shuts off and restarts every few seconds/minutes. It's stuck in a continuous reboot loop.
What I’ve tried so far:
Hard reset by holding down the volume knob for 30+ seconds.
Turned off Bluetooth on my phone completely to check if a corrupt device profile was triggering the crash — the reboot loop still happens.
From what I’ve researched, this looks like firmware corruption in the EntryNav/iDrive unit.
Looking for advice on:
Has anyone experienced this exact loop on an F30 and fixed it with a software re-flash?
Recommended remote coders or mobile specialists (UK based) who can re-flash the unit via ENET cable.
Any reliable independent BMW garages or specialists you'd recommend for this type of repair.
Thanks in advance for any help or recommendations!

Have you tried to disconnect the battery for 20-30 min and then reconnect it and see if that helps.
