Audi A3 Radio Code: How to Retrieve Your Unlock Code Online

The Audi A3 is one of the most popular premium compact cars in the UK. Whether you drive an 8L, 8P, or 8V, the head unit can lock after a power interruption. This guide explains how to retrieve your Audi A3 radio code and enter it correctly.

Radio Types by Audi A3 Generation

Generation	Year	Radio	Code Compatible
A3 8L	1996–2003	Chorus, Concert, Symphony	Yes
A3 8P	2003–2012	Concert II/III, Chorus, Symphony, RNS-E	Yes
A3 8V	2012–2020	MMI, Audi Sound System	Via dealer/VAGCOM

SAFE Mode and the Waiting Period

Like all VAG group vehicles, the Audi head unit enters SAFE mode when power is lost. Leave the radio powered for one hour, switch it off briefly, then back on. The display will show 1000 and you can enter the Audi A3 radio code.

Finding the AUZ Serial Number

Audi radio serial numbers start with AUZ followed by a combination of letters and digits. Find it by:

1. In SAFE mode, pressing TP and RDS simultaneously (Concert/Chorus units).
2. Or removing the radio with Audi DIN release keys and reading the label.

Retrieving the Radio Code

1. Go to RadioCodeLookup.com/brands/audi.
2. Enter the AUZ serial number.
3. Receive your Audi A3 radio code.
4. Enter the four-digit code using the preset buttons and confirm.

Frequently Asked Questions

Does the Audi A3 8V (2012+) need a radio code?

Most A3 8V models with MMI no longer use a traditional stereo code. The unit is paired to the vehicle via the VIN. Contact your Audi dealer if you have trouble with an 8V system.

Can I use the same code in another A3?

Yes. The Audi A3 radio code is linked to the radio's serial number, not the car. The code remains the same regardless of which vehicle the unit is fitted to.

My Concert radio shows SAFE but the button combination does not work. What now?

On Concert II and III models the combination sometimes differs. Try FM1/FM2 + RDS, or remove the radio to read the serial number from the label.
