Help with CCC unit

citysmythrone · 05-10-2021, 04:08 PM

One day I was started the car and the CCC screen was stuck in the endless BMW boot cycle and ended up completely turning off. I tried the 3 finger reset to no avail. Also tried using a fiber optic loop at the amp in the trunk and it didn't work as well. Scanned the car and got these codes (in the picture). Any ideas?

List of Codes:

S0067: No communication possible with audio system controller

S0374: No communication possible with aerial tuner

S0375: No communication possible with headunit

I had my CIC fail in the same fashion, ended up change the unit and no more issues. Not sure if there are tricks with the CCC though.

How old is your battery? I parked my E93 for two months. The battery got very weak and CCC was behaving erratically, failing to play music, throwing SOS and other errors, not responding to the three key reboot.

After some driving and charging up I restarted the car and it was back to normal.
