BMW F11 525xd – Navi Professional (CIC) reboot loop
Hi everyone,
I’m looking for some advice regarding BMW 525 xDrive F11 with Navi Professional (CIC). On first start of the day (usually when the car is cold), the iDrive goes into a reboot loop. BMW logo appears, system restarts several times and behaves unstable right after engine start. After a few minutes, everything works normally and during the rest of the day there are no problems. Additional info: Battery is new Engine starts without issues Problem mainly happens on first start, not every single time My questions: Could this be a failing HDD inside the CIC unit? Known CIC reboot loop issue on startup? Possible hardware problem inside CIC (HDD / cold solder joints)? Would HDD replacement solve this? Any input or experience would be very helpful. Thanks a lot 🙏 |
