I'm trying to get into the control head for the MMI. I need the security access code 16 and VCDS isn't popping up the bubble for this one. Does anyone know the code? this is on a 2004 A8L

I think you need the car hooked to the mothership in Ingoldstadt. Meaning take it to a dealer and they will code it to your vehicle's ECU for an hour of labor. IIRC, Fred Lavery in Birmingham is like $125/hr these days.

There is a guy in Europe who has bootlegged a method for like $40.00 US as long as you have the right interface and internet connection on a computer you can hook to the car.

Not sure of his CONtact info but someone here can chime in with it.

Two different subjects: 1. used modules with component protection that need to be configured to car, and 2. coding a module that already functions for some feature where it requires a security access code. Not sure from OP which it is. Mister Bally answered #1. For #2, it does sometimes pop up the bubble. There is also a code generator on the web which I have stumbled upon in past, or sometimes posts with a given code for a module if I search for it.

If it's cp he can do it from Poland but you need a clone vas 5054a and Internet connection
Usually charges 50 euros

I've got an apt scheduled with Audi of Rochester Hills for Tuesday. Service advisory thinks upgrading MMI firmware will fix lost car menu. Looking at $250 he said. Ive got the CD's but not sure if it's worth upgrading myself .

If that fails don't let them sell you a new head unit for thousands of monies.
Let us know the result of your visit to Audi.

Also what is the error code for the Mmi head unit 07

There isn't a malfunction for the 07 Control Head. there is on the central conv. , the battery regul. the rear left door, the tire pressure module, and telematics.

You more then likely just have a bad "car button" from the "coke-a-cola" spill that you did not tell us about from the beginning.....

you could pick up a cheap control board off ebay, or if you are good with circuits and soldering you could solder in a touch pad or just a jumper to simulate the button and see if the car menu appears.

I did think of using a short wire or paperclip to jumper the two points on the switch to see if the button was bad. I may still do that.


EDIT: Going to pull the center control out and get to the circuit board to jump pins on the button. I figure if the micro switch failed from the soda spill then I will solder out the telephone M-switch with the car M-switch since I know it works and do not use this feature. Will report back with updates this evening.
