MMI WONT POWER ON!!!!
I have a 2005 Audi A6 and my MMI wont work. The screen is black, the radio wont come on or anything. The CD changer still operates as normal. I believe it has something to do with my battery but Audi disagrees. I went in for two oil changes and each time they told my battery failed inspection. I didnt worry about it because the car still ran. I was told that certain systems would shut down to preserve the battery. One day it just would not come on. At first the side mirrors stopped shifting down automatically when I put the gear in reverse. Next the MMI went black. I am tired of riding in silence and I have no idea what the problem is and I don't to take it to the dealership and pay god knows what just for them to tell me what the problem is!!!! SOMEBODY HELP

You don't use the MMI to code a new battery, you do it with your vag-com (VCDS).
Look here, 7th screen - http://www.ross-tech.com/vcds/tour/recode_screen.html
If you don't code your new battery, the car thinks it still has the old one so will carry on shutting things down until it is told there is a new battery.
Has it been cold where you are?

Ok I may sound slow but...where can I get Vag-Com n how much is it? Once it is reprogrammed will everything turn back on? None of the lights on the cluster (cd, fm/am, nav, car, setup) illuminates anymore. If I do take it to the dealer do I just have them recode the battery?

if I were you; don't have a vag, don't understand how to program the car, etc...I would just go to the dealer and they will be able to do it very quickly for you.
every audi dealer and good Indy audi mechanic has a vag com and they need to pair the battery to the car. however this is not guaranteed to solve your issue, but most likely will

It's going to run under $300 for the new battery and recoding.
But you should get yourself a ross tech vag com. Check ebay but watch out for the fake one or buy one direct with support for one year with ross tech.

But if you do research you could find the battery for $150

My radio mmi isn't working and is completely black. when it first started the screen came on and just the audi mmi logo screen came in but after a while it would go black and nothing else functioned the entire time. I would turn off the car and turn it back on and the screen would do the same but a light thumping sound came from the speakers as if it was the amp trying to work but wouldn't. then a day or so later i turned the car on and nothing came on the screen was black and the console buttons don't function period but still you'll hear the light thumping sound as if the amp is struggling to work. Does anyone know what it might be? my feeling is the amp and i remember not long before the issues the left side (driver side rear) of my rear trunk panel where the amp is at had some water and i had to use a towel to soak it up. Do i need to replace my amp? is the amp capable of completely shuting down the MMI from working if it goes bad? It's a 2005 a6 3.2 liter quattro 4 door sedan
