Idrive software update fixed error codes?

My GF just got a 2012 BMW 335I with 45000 miles on it.

I got out my code reader and started checking for codes and saw some of the following:

801206 Blower output stage: Undervoltage or overvoltage detected
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.
