Audi Chorus Radio Code – AUZ Serial Number Unlock Service
Is your Audi Chorus radio displaying SAFE or asking for an anti-theft PIN?
Compatible Audi Chorus factory radios can use an AUZ-series serial number to identify the individual radio. If your Chorus unit is requesting a normal numerical security PIN, our online service provides security-code information for compatible radios using the identification information from the radio itself.
This is a completely digital service. There is no physical product and no shipping required.

Before ordering, locate the complete AUZ serial number and carefully verify every character.
Do not order only using:
Audi Chorus
The exact radio identification is important.
What Is an Audi Chorus Radio?
Audi Chorus is one of the factory radio families installed in various Audi vehicles across several generations.
Depending on production period, market, and hardware version, different Chorus radios can use different manufacturers, Audi part numbers, and AUZ serial-number formats.
The radio may request an anti-theft PIN after power interruption, radio replacement, removal, or installation of another factory radio.
The actual installed radio should always be identified before ordering.
Audi Chorus Radio Code
A compatible Audi Chorus radio may use a numerical anti-theft security PIN.
The radio can request security verification following battery work, electrical power loss, radio removal, radio replacement, installation of a used radio, dashboard repairs, or other electrical work.
If your Chorus radio displays SAFE or a normal numerical PIN-entry screen, the correct security-code information may be required before normal operation can continue.
Audi Chorus AUZ Serial Number
Compatible Audi Chorus radios can use AUZ-series identification.
Depending on the exact Chorus version, serial-number families encountered on compatible units can include formats such as AUZ1Z, AUZ2Z, and more specific prefixes within those families.
The complete serial number is required.
Do not submit only a short prefix such as:
AUZ1Z
or
AUZ2Z
Additional characters identify the individual radio.
How to Get an Audi Chorus Radio Code
First, confirm that the installed radio is actually an Audi Chorus unit.
Turn the radio on and check the exact message displayed. A compatible unit may show SAFE or a normal numerical security-code request.
Next, locate the radio identification information. Depending on the exact Chorus generation, the AUZ serial is generally found on the identification label attached to the radio chassis.
Copy the complete AUZ serial number exactly as printed. Do not shorten it and do not use a serial number found online.
Also record the Audi part number and manufacturer information if available.
Carefully verify every letter and number before submitting your order.

For compatible Audi Chorus radios, the corresponding security-code information is delivered digitally.
No physical shipping is required.
Where Can I Find the Audi Chorus Serial Number?
The serial number is commonly printed on an identification label attached to the metal radio chassis.
Depending on the vehicle and radio installation, the Chorus unit may need to be pulled forward from the dashboard to access the label.
The label can contain several identifiers, such as the AUZ serial number, Audi part number, manufacturer information, product number, barcode, hardware information, and production details.
When requesting a serial-number-based radio code, carefully locate the complete sequence beginning with:
AUZ
Check the Audi Chorus Serial Carefully
Every character matters.
Characters such as 0/O, 1/I, 5/S, and 8/B can sometimes be difficult to distinguish.
Never guess an unclear character.
One incorrect character may prevent correct radio identification.
If the identification label is faded, damaged, scratched, or difficult to read, contact us with a clear photograph before ordering.
Audi Chorus AUZ1Z Radio Code
Some compatible Audi Chorus units use serial numbers within the broader:
AUZ1Z...
family.
More specific AUZ1Z serial formats exist, so always submit the complete serial exactly as printed.
Do not remove or change any character from the prefix.
Audi Chorus AUZ1Z1 Radio Code
Compatible Audi factory radios can use an AUZ1Z1 serial format.
If your Chorus radio serial begins with AUZ1Z1, copy the complete sequence.
AUZ1Z1 alone is not the complete radio serial.
Audi Chorus AUZ1Z2 Radio Code
AUZ1Z2 is another Audi serial-number family.
If your Chorus radio label displays an AUZ1Z2 serial, submit that exact identification.
Do not change AUZ1Z2 to a similar-looking AUZ prefix.
Audi Chorus AUZ2Z Radio Code
Compatible Chorus radios can also appear within the broader:
AUZ2Z...
serial family.
The exact characters after AUZ2Z are important when identifying the specific radio.
Audi Chorus AUZ2Z2 Radio Code
AUZ2Z2 is particularly relevant to compatible Audi Chorus / Grundig factory radios.
If your Chorus unit has an AUZ2Z2 serial, provide the complete serial number from the radio label.
Do not submit only:
AUZ2Z2
The remaining characters identify the individual radio.
Audi Chorus Grundig Radio Code
Certain Audi Chorus radios were manufactured by Grundig.
The identification label on these units can contain an Audi AUZ serial, Audi part number, manufacturer information, and other product identifiers.
For compatible Chorus Grundig radios using AUZ identification, the complete AUZ serial is the important identifier when requested.
Do not confuse the Audi AUZ serial with a Grundig product number or Audi part number.
Audi Chorus SAFE Radio Code
Audi Chorus radios can display SAFE when the anti-theft system is active.
SAFE can appear after electrical power interruption, radio removal, installation of another radio, or previous incorrect PIN attempts.
If SAFE appears, stop entering random numbers.
Identify the exact radio, locate the complete AUZ serial, verify every character, and request the correct security-code information.
Audi Chorus SAFE 2
Some Audi radios may remain in a more restrictive SAFE state after incorrect PIN attempts.
Customers sometimes refer to this as:
SAFE 2
Our service provides the security-code information for compatible radios, but it does not bypass built-in radio waiting periods or security timers.
If incorrect codes have already been entered, avoid further guessing.
Audi Chorus Code After Battery Replacement
Depending on the exact vehicle and radio configuration, a Chorus radio may request security verification after electrical power has been interrupted.
If your radio worked normally before battery replacement but now displays SAFE, identify the radio and locate its complete AUZ serial before ordering.
Audi Chorus Code After Battery Disconnect
Battery power can also be interrupted during electrical repairs, starter or alternator work, dashboard repairs, wiring work, accessory installation, or radio removal.
If the Chorus radio requests a PIN after power is restored, use identification information from the radio itself.
Audi Chorus Code After a Dead Battery
A fully discharged battery can cause a complete electrical power interruption.
When power returns, a compatible Chorus radio may restart in a security state.
Do not immediately try common combinations such as 0000, 1111, 1234, or the vehicle production year.
Locate the complete AUZ serial instead.
Audi Chorus Replacement Radio Code
A replacement radio has its own serial number and security information.
If another Audi Chorus radio has been installed in your vehicle, use the serial from the replacement radio currently installed.
Do not submit identification information from the original radio that was removed.
Used Audi Chorus Radio Code
Used Audi Chorus radios are frequently installed as replacements.
A second-hand radio may originally have been installed in another Audi.
If the used Chorus unit displays SAFE or requests a normal numerical PIN and has compatible AUZ identification, our service may be suitable.
The replacement radio retains its own serial number.
Audi Chorus Radio Code by Serial Number
Our standard Audi Chorus service is based on identification information from the radio itself.
The AUZ serial identifies the individual radio and is therefore more useful than ordering only by vehicle model or radio appearance.
Always submit the complete serial exactly as printed.
Audi Chorus Serial Number vs Audi Part Number
The Audi part number and AUZ serial number are different identifiers.
The part number identifies a radio model or hardware version.
The AUZ serial identifies the individual radio.
Multiple radios can share the same Audi part number while having different serial numbers.
When the service requests the radio serial, provide the complete AUZ identification.
Audi Chorus Serial Number vs Vehicle VIN
The vehicle VIN identifies the car.
The AUZ serial identifies the radio.
These numbers are not interchangeable.
This distinction is particularly important when a used or replacement Chorus radio has been installed because the radio retains its own serial number regardless of the vehicle in which it is currently fitted.
Audi Chorus Radio Code by VIN
Customers sometimes search for an Audi Chorus radio code by VIN.
Our standard service is based on identification information from the radio itself.
If your Chorus radio has an AUZ serial number, provide the complete radio serial.
This is a serial-number-based radio-code service, not VIN decoding.
Audi Chorus vs Audi Concert
Audi Chorus and Audi Concert are different factory radio families.
Although they can appear in similar Audi generations, the radio model alone does not determine the serial prefix or security procedure.
If your radio is Chorus, use the identification from the Chorus unit itself.
Do not select a Concert service only because the radios appear similar.
Audi Chorus vs Audi Symphony
Audi Symphony is another factory radio family.
Chorus and Symphony units can differ in hardware, manufacturer, functions, Audi part numbers, and serial identification.
Always verify the actual radio before ordering.
Audi Chorus vs RNS-D
Audi RNS-D is a factory navigation system, while Chorus is a traditional factory radio family.
If your installed unit is RNS-D Navigation Plus, use the RNS-D-specific identification rather than a Chorus service.
Audi Chorus vs RNS-E
Audi RNS-E is another factory navigation system.
It is different from Audi Chorus in hardware, navigation capability, serial identification, and security procedure.
Do not identify a radio solely from the vehicle model.
Audi Chorus vs BNS 5.0
Audi BNS 5.0 is a factory navigation system and is different from Audi Chorus.
If your unit contains integrated navigation and is identified as BNS 5.0, use the appropriate navigation-system service.
Audi Chorus and Component Protection
A normal Audi Chorus numerical security PIN is different from Component Protection.
A standard radio code does not remove Component Protection.
Our service does not remove Component Protection, pair modules to a VIN, perform online Audi adaptation, modify radio software, or bypass vehicle security systems.
If the system displays Component Protection, restricted functionality, authentication, pairing, configuration, or module adaptation required, contact us before ordering.
Which Audi Models Can Have Chorus Radios?
Audi Chorus radios were used across various Audi vehicles depending on model year, market, equipment specification, and later radio replacement.
Possible applications include Audi A2, A3, A4, A6, A8, TT, and other compatible Audi models.
However, the vehicle model alone does not confirm the exact radio.
Always inspect the installed unit.
Audi A3 Chorus Radio Code
Compatible Audi A3 vehicles can use Chorus factory radios.
If your A3 Chorus displays SAFE, locate the complete AUZ serial from the installed radio before ordering.
Audi A4 Chorus Radio Code
Audi A4 vehicles were offered with several different factory audio systems.
If the actual installed unit is Chorus, use the serial information from that radio rather than relying only on vehicle year.
Audi A6 Chorus Radio Code
Certain Audi A6 vehicles also used Chorus factory radios.
Always verify the complete AUZ serial and radio model.
Audi TT Chorus Radio Code
Audi TT vehicles can also use compatible Chorus factory radios depending on model generation and equipment.
If the installed radio displays SAFE, identify the actual Chorus unit and complete serial number before ordering.
Avoid Guessing Your Audi Chorus Radio Code
Repeated random PIN attempts are not recommended.
Incorrect codes can cause a temporary security lockout.
The correct approach is to identify the Audi Chorus radio, locate the complete AUZ serial number, verify every character, request the correct security-code information, and enter the PIN only when the radio is ready.
Why Exact Audi Chorus Identification Matters
Audi used several Chorus hardware versions across overlapping vehicle generations.
Two radios can look similar while using different manufacturers, AUZ prefixes, Audi part numbers, hardware, and security procedures.
Before ordering, verify the radio model, complete AUZ serial, Audi part number if available, manufacturer information, and exact security message displayed.
Do not order solely from the physical appearance of the radio.

What If My Audi Chorus Shows a Different Message?
Not every security message represents a standard numerical anti-theft PIN request.
If the display shows something involving Component Protection, authentication, vehicle pairing, programming, configuration, or restricted functionality, the standard radio-code service may not be appropriate.
Contact us before ordering if the display does not show a normal SAFE or numerical PIN request.
Before Ordering an Audi Chorus Radio Code
Confirm that the installed radio is actually Audi Chorus.
Locate the complete AUZ serial number.
Check the exact prefix, such as AUZ1Z, AUZ2Z, AUZ1Z1, AUZ1Z2, AUZ2Z2, or another format printed on your radio.
Verify every character directly from the original identification label.
Check the Audi part number and manufacturer information if available.
Confirm that the radio displays SAFE or requests a normal numerical security PIN.
Avoid random code attempts if previous PINs have already failed.
