How to Find Audi A4 Radio Code Serial
Method 1
There are 2 types of Audi A4 serial numbers (Audi A4 Navigation Plus see method 2). It is quite simple to remove your Audi A4 radio. You will need a set of radio release keys (PC5-83). These are inexpensive tools, you can obtain them from Amazon.
Once you have the radio release keys, push them into the 4 holes in each corner of the radio (See image), apply a little pressure and the radio will release from the dashboard. The radios label will be located on the radio's casing.
The Audi A4 radio serial is a 14 digit serial number for example AUZ1Z1F6412082. Please see image for reference.
Method 2
How to show your Audi A4 radios serial on the radios display.
With the Audi Navigation Plus system the serial can be displayed on screen rather than taking out the radio unit.
