    S5 2G MMI help!!

    Guest-only advertisement. Register or Log In now!
    My mmi turns on when I press the power button but then it shuts right back off. Can someone give me a clue as to what's wrong with it?

    SN: has anyone successfully upgraded to 3G/3G+ without spending a ridiculous amount?

    Locate button: SETUP button. big control knob. upper-right soft button.
    Press and hold those button at the same time.
    After two seconds release buttons. Audi MMI screen will go black for few seconds and system will reboot.

    I pulled the fuses and that didn't work. There's also this grinding noise that's coming from behind my dash when the mmi turns back off

    I don't know squat about the 2G system itself, but is it possible you're actually hearing the hard drive that stores the MMI software, jukebox, etc.? They didn't use solid state drives to my knowledge, and it's a matter of time before those spinning drives have issues. If the drive configuration is the same as the 3G system, it would be mounted to the bottom of the CD/DVD head unit. You have to remove the head unit to extract the drive.

    This thread is partially relevant (if it is a drive issue) because it shows you where the drive is actually located. The thread is actually about replacing the HDD with an SSD: https://www.audizine.com/forum/showt...-3G-HDD-to-SSD

    Its probably the control module then located behind the mmi screen. I had the exact same issue you have. Did you try the mmi and radio fuses on the sides of the dash?

    Yes I tried those fuses but no luck. I think I may take it to the dealership to find out more info. Don't wanna waste money guessing
