My Peugeot 3008 has an infotainment system that randomly reboots. When it does this, the SOS light blink a code as well as the Peugeot assist button. The Bluetooth also stops working when this happens. I changed the battery and the issue stopped for a long time but the Bluetooth did not work. Eventually the Bluetooth started working again after some months but the infotainment now also reboots again.
