801A55 DWA: The alarm has been activated
CD0487 ZGM: Sycronisation process for FlexRay failed

She hasn't added anything aftermarket to the car like stereos or anything and all I did was clear the codes and update the BMW iDrive software to the latest. Now I get no error codes. Is it possible that the BMW iDrive software fixed the issues? I thought the update was only for the interface software for the screen.
Software did not fix any of that. They are just Intermittent failures.
Just keep scanning it every couple weeks and see what comes back and at what frequency.
