How to find your Audi A6 radio serial number

Where it is

On the label

  1. Check the radio card in the handbook wallet first.
  2. Otherwise take the radio out with radio removal keys.
  3. Copy the serial from the label: 14 letters and numbers starting VWZ, AUZ, SKZ or SEZ.

Photograph the label rather than copying it by hand — 0 and O, 1 and I are easy to mix up.

RADIOPush both keys in until they click, then pull the radio forward

It comes out with a pair of radio removal keys. Which keys, and where they go: how to remove a car radio.

Tips for your Audi A6

  • If the car has the round MMI controller in the console, there is no radio code to buy.
  • C5 radios are double height: four keys, and take the weight as it comes out.
  • The radio card in the wallet has the serial on it.

Audi A6 radio code questions

Which A6 radios can you do?

The C5 cars up to about 2004 — Chorus, Concert, Symphony and Navigation Plus with an AUZ serial.

My A6 is a 2007 with MMI.

MMI is matched to the car, so there is no code we can work out. An Audi dealer can help.

Is the serial on the screen?

No, Audi radios keep it on the label.

Can you do every Audi A6 radio?

For 1997–2004, yes: the code appears on screen as soon as you have paid; for 2004 on, not at the moment. The free check tells you which yours is before you pay.

Which radio does my Audi A6 have?

It depends on the year. 1997–2004 (A6 C5): Chorus, Concert, Symphony and Navigation Plus. 2004 on (A6 C6 and later): MMI systems. Radios were often swapped, so the serial on yours is what counts.

What does the serial look like on an Audi A6?

14 characters starting AUZ, on the label or the radio card. For example VWZ1Z2S4292662.

Do I have to take the radio out of my Audi A6?

Yes: the serial is on the label, not the screen. It comes out with a pair of radio removal keys.

How do I enter the code on an Audi A6?

Button 1 sets the first digit, button 2 the second, and so on, pressing repeatedly to increment. Confirm by holding either rocker switch for more than two seconds.
