Audi A2's Most Common Radio Code Triggers
Your radio may lock automatically when it detects a power interruption.
These are the some well-known scenarios that trigger the radio code prompt.
Battery Change Problem
After a battery replacement, your radio may show a CODE message.
This happens because the radio detects a power reset, which triggers the anti-theft system.
Other Situations That Trigger a Radio Code on Audi A2
- Installing a used head unit will trigger the original anti-theft code.
- After an ECU or software reset, the radio may enter security mode.
- A fuse removal can cause the Audi A2 radio to lock.
- Jump-starting the vehicle can trigger anti-theft mode, requiring the PIN.
What is a Radio Code and Why is it Important?
A radio code, also known as an anti-theft code is a unique numeric unlock key that reactivates your car audio system after it has been disabled.
This security code is triggered when the radio loses power.
Automakers include this feature to protect factory stereos from theft.
If power is cut, the radio locks automatically and requires the unlock CODE before it can function normally.
Once the right combination is entered, the stereo is unlocked.
Quick Fixes Before Paying for a Radio Code
Before you pay for it, it's worth checking a few places where the code is often already written down.
Some owners find their Audi A2 radio code without needing any tools or paperwork.
Here are the most common things to check first.
Check the Car Itself
- In the owner's manual, often on a code card.
- Inside the glovebox, sometimes on a small card.
- In the boot compartment, on a radio label.
- In your maintenance booklet from the previous owner.
- On the head unit itself, if it was serviced earlier.
Getting a Audi A2 Radio Code from the Dealer

In most cases, you need to visit or contact them and show vehicle documents.
When it is verified, they can generate the original unlock code for your radio.
Disadvantages:
- You usually need to book an appointment and bring vehicle paperwork.
- Dealers often charge a fee for the lookup service and it's sometimes more than 100$.

Finding the S/N on a A2's Radio
To get the correct radio code, you first need the serial number from the radio.
Depending on your A2, you can see it on the screen or find it on the radio unit itself.
It's usually written down as S/N, SN, Serial, Serial Num., Serial Number...
These are the most common ways to find it:
1. View the Serial Number on Audi A2's Display
Audi A2 radio does not display the serial number on the screen.
Unfortunately, the unit must then be extracted from the dashboard to find the serial on a manufacturer label on the radio casing.
2. Locating your Serial on the Radio Unit
To find the serial number, you'll need to take out the head unit from the dashboard.
- Start by turning off the vehicle and removing the trim panel.
- Next, unscrew the mounting bolts and slide the radio out to check the sticker on the back of the radio. Be careful not to damage the cables that the unit is connected to.
- Write down full serial number precisely and then come back to the website.
- Know that serial number and part number are not equal. You will find both on the sticker, and you only need for the first one.
