Audi Radio Code: Serial, SAFE and Compatibility
Prepare an Audi radio code request with the correct unit details and distinguish a code prompt from issues that need workshop diagnosis.

Read the Audi radio message before choosing a service
A request for a radio security code needs the correct unit information. If the message is unclear, photograph it before changing settings. SAFE, a code-entry screen, a blank display and a component protection message should not be treated as the same diagnosis.
The word calculator in a search result does not establish compatibility. Neither an Audi model name nor an infotainment family name proves that a particular unit accepts a separately supplied radio code. Check the fitted unit before ordering.
Concert, Chorus, Symphony, RNS-E or MMI?
These names help describe Audi equipment, but they do not replace the unit's serial and part numbers. Different versions can have different procedures. This guide does not claim that every unit carrying one of these names is covered by our code service.
Use Audi's online owner's manual to find the instructions for the vehicle. Audi's portal supports selection by vehicle details or VIN for available manuals. If a previous owner installed another radio, ask a workshop which instructions apply to that fitted unit.
What to send for an Audi compatibility check
- A clear front-panel photo and the exact on-screen message.
- The complete serial number and a readable photo of its label.
- The part number and equipment name, when available.
- Whether the radio was replaced or the message appeared after battery work.
See the serial-number guide if the label has multiple identifiers. Use the Audi radio code service page for the applicable request; ask support before paying if the unit or message is uncertain.
When a workshop is the better next step
A replacement unit that requires adaptation, a component-protection message or an electrical fault needs the correct technical assessment. A separately supplied code is not a general repair or adaptation service. Avoid repeated guesses or undocumented reset procedures.
Common questions
Can you check an Audi A3, A4 or Q5 from the model name?
The model helps describe the car, but support needs the installed radio details to assess the request. Do not assume that a code advertised for the same model fits your unit.
How much does the Audi code service cost?
Use the current order page for the applicable price and currency. This guide does not publish a fixed price that could become outdated.
What if a code is rejected?
Stop further attempts, check that the ordered serial number matches the fitted radio and record the exact response. Contact support with the order reference and follow the radio-specific manual for any waiting period. There is no universal unlock timer or confirmation-button sequence in this guide.
