AUDI MMI 3G HEAD UNIT SERIAL NUMBER - 2002 Audi A6

Force reboot . Press the setup button and the centre knob and the right top knob together ,as soon as you leave the 3 button in will reboot

Take vehicle to the dealer and have tech plug it into the computer for error codes.

NEED VIN AND NAVI SERIAL YES THEY ARE CORRECT.WITHOUT THOSE 2 IT IS IMPOSSIBLE FOR THEM TO GIVE U THE CODE.CHECK THE RADIO MANUAL FOR A STICKER AND SPECIALLY LOOK FOR A14 DIGIT NUMBER STARTING WITH AUZ....IF U CANT FIND IT U MUST TAKE OUT THE UNIT..IFU CAN SEND ME BOTH I WILL BE ABLE TO PROVIDE U WITH HE PIN.IF U NEED MORE INFO ON HOW TO TAKE OUT THE UNIT LET ME KNOW..

Can't work on it until you learn the system

Check the schematic on alldata or whatever you have

I have a brand new A6 and the MMI is not working. Keeps going on and off. After 4 trips to the dealer, Audi is still not owning up to the problem.

you nid mmi circuit board replaced,happened to me after spilling coffee,audi wanted to replace the whole thing with a new mmi system for a lot of money, but Ifound someone to change circuit board for abt £200 which is not bad,the only thing is you have to take out the whole centre console and air con unit and armrest off,so u nid some one who knows how to do it.check on tyresmoke and post from there,will respond and give you more info.The previous owner must have spilt something and panicked and sold the car without being honest.It sucks..........

There where 3 language choices in the original MMI software. English, French and Spanish. I assume since you're getting German, the car is an EU A8, not North American. German was not in the North Amercan A8. Only the newer software from MY 07 up have no language choice on startup. It is set under car, setup menu. If you set the language and it defaults back to German, I would at least check with the dealership to see if there is an MMI update for your vehicle. If not, then the main head unit (07) may be faulty, since the settings are stored there.

I have a 2006 A8 and if you need help with the command say "help mmi" or when you are in one of the following modes: radio, CD, or Navigation. you can say "help ." This should provide you with all the commands the voice command can understand.

Sorry, not posible.
