However, the service advisor did also state that Audi is concerned about the 2015 MMI issues and he asked me to pay close attention to exactly what functions I was performing if/when the MMI shuts down again. Best I can gather, this is a pretty widespread issue with 2015 and due to the nature of the problem they are having a hard time trapping any error codes, although it seems to happen in the fiber loop.

Anyway: less than 15 minutes after heading home from the dealership the MMI went dark. At that time I was running NAV and had recently turned on Google view and at the EXACT time the unit went dark I was attempting to change the Sirius channel from preview to a different station by using the steering wheel scroll button. I think the bottom line for testing is they actually need to be using different functions in order to cause the failure; simply letting it sit idol does not cause the fault.

I take Q back to dealership on Monday morning so they can take another look!

At what point do I request they replace the entire MMI?

Here is what I've documented:

--Problem started on Monday, 11/17 (on day 2 after pick up)

--Problem occurs after I have been driving for approximately 25 - 40 minutes.

--I noticed last night that, just before the screen goes black and MMI dies; the screen actually brightens up to what seems to be max bright setting.

--Pressing the "screen on" button will bring the MMI back up... but
...Steering wheel buttons will not work.
...Backup/Front cameras will not come up, even though the MMI screen is on - it stays on what ever setting it is currently on (usually Media).

-- MMI will not immediately shut down after engine is turned off and door is opened
...nor will it shut down even after doors are locked.

-- Letting the car sit for about 20-30 minutes seems to resolve the problem - at least until I drive for another 25+ minutes.

Here is a video showing engine off, door open and MMI still running.

Theory: MMI is overheating.


Anyone else experiencing these symptoms?

On Monday morning (11/17) the MMI screen went black and MMI shut off when I was about 5 minutes from my office. After getting to the office, I left the car shut off for about 30 minutes, when I started the car, the MMI came back up to the "initilizing" screen. I chalked it up to a fluke.

BUT - on my way home tonight (11/18), about 5 minutes from home. the MMI shut down again. The shut down means the screen is black and all function buttons were out. (see pics). I will be taking the car back for the dealership to check it out and fix the issue.

Have any of you had the same issues? On a 2 day old Audi?
