You cannot tell the battery condition directly by the surface or terminal Voltage. 13.2-13.3 Volts is actually too high. Either there was a big surface charge or the battery may be bad with a bad cell.

Did anyone put a tester on the battery?

Did you put a Volt meter on the battery and turn the headlights on for 2 minutes and see where the terminal Voltage ended up.

The battery may be fine, but nothing posted has convinced me that it has been properly tested and passed.

Also put a Voltmeter on the battery with a Min Hold while the engine is started and see what the minimum Voltage ends up being during cranking.

You may well also have an iDrive problem. Cannot recall if the CCC has a hard drive like the CIC systems. Might be the drive is going if there is one?
