Battery status capacity bar in MMI 3G
Did you know you can enable a battery capacity bar in your MMI 3G?
Instructions:
- Press CAR + SETUP for 6 seconds to enter the hidden developer menu
- Select “car”
- Select “cardevextdevicelist”
- Check the “Battery” checkbox
- Press return key
- Select “carmenuoperation”
- Set the battery value to 5
- Press return key
- Press CAR key (exit hidden menu)
- Restart the MMI: Press and hold down the function keys 1 (Setup), the control button 2 and the control key at the top right 3 simultaneously until the MMI system shuts down. Release keys -> MMI system reboots.

- You’ll find a new “Battery” entry in your CAR menu
Some more screenshots:
The hidden menu needs to be unlocked first with VAG-COM/VCDS or VAS 505x. See here for instructions.

Just like in the MMI 2G, there’s a hidden menu in the MMI 3G too. I don’t encourage anyone to enable the hidden developer menu...

That’s cool :-) Thanks!
What does the “Sliding Roof” option in the hidden menu do?
Why must battery set to 5 and not to 1 or 7 or 9 ?
Maik, you don’t have to set it to 5. This just indicates the relative position in the MMI menu. I thought 5 was nice :)
phxflybox: If you don’t have a sliding roof it will – obviously – do nothing. In certain cases your car may transform into a convertible but that is just a rumour.
Well, I do have a sunroof. I like the convertible idea but don’t think that’s happening! Anyway, any other ideas as to what this feature does?
