How to Find Audi A4 Radio Code Serial

Method 1

1. How To Find Your Audi A4 Radio Serial.

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 and are around £3 - £5, you can obtain them from a local car audio shop or Halfords.

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.
