Sirius presets and iDrive issues

[slowlanemcvane]

So I'm still having problems. I disconnected the battery from the car, put it on the charger overnight last night, and took a voltage reading on it this morning from a multimeter. It read 13.3 volts at the posts. I took it to Autozone this morning, as well, and they confirmed 13.28 volts, indicated a good battery.

So I came home, put the battery back in the car, started it, and got the obligatory 4WD/AWD/DSC fault from the loss of power to the steering angle sensor. I cleared that with the lock to lock wheel sweep.

IDrive is still acting funky, it continuously freezes on me. It seems to still have the Sirius presets that I set up a couple of days ago still stored in memory, but the darn thing froze three times while I was attempting to set the date and time. I rebooted it with the eject-eject-mute combo a bunch of times, but it never stays unfrozen, and sometimes blacks out and returns to the BMW screen 2-3 times before finally playing music.

Seems that I've pretty much ruled out the car's battery and charging system. Am I looking at a failed CCC or something at this point?

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?
