When you disconnect the battery, are all the settings saved when you re-connect it? Should I record all the service numbers( break pads, oil, etc...) before disconnecting it?

Do I have to re-initialize anything after reconnecting the battery such as the steering angle sensor, etc....?


Thanks!

You will need to reset active steering for sure. I believe you turn the wheel all the way to the left, then all the way to the right and center and it should reset.

do the steering turns, and reset the clock/date. service intervals are stored.

I disconnected the negative on the battery for about fifteen minutes, on Saturday and apart from the clock reset that was it, active steering was okay. Must only need resetting if the battery is disconnected for a longer period as when I changed the battery recently.

Will there be something on the iDrive prompting something regarding the steering needing to be reset or should I just do it anyway?

reseting the steering is just a matter of turning the wheel from lock to lock and then back to center.
might as well do it, although it might not be necessary.

You will get a message on your iDrive regarding the AS.

Thanks guys! I'm hoping and planning on installing a BMS Power Box this weekend. I emailed Burgertuning and they recommend disconnecting the battery even though others didn't. I just want to play it safe.

IMO the wheel right-wheel right business is not necessary to reset active steering. I have found it to reset itself in about 30 seconds of driving.
