Audi TT's Most Common Radio Code Scenarios
Many drivers encounter security code prompts on their TT after electrical work.
Below are the most common situations when this can happen.
Lock After a Battery Work
When the battery is replaced, the Audi TT radio locks automatically.
This security feature is designed to prevent theft by disabling the radio after electrical reset.
Other Situations
- After a jump-start, the radio may reset and request a radio code.
- When the radio is removed, it usually requires the original code.
- If a fuse is pulled, the radio can enter anti-theft mode.
- After a software update, electrical repair, or an ECU reset, some Audi TT radios display a CODE message.
Places to Check Before Paying for a Radio Code
Looking for a free Audi TT Radio Code? Actually, you may already have it.
In few cases, the code may already be available in the vehicle or in the documentation.
Check these places to save time and money before using an online lookup tool.
Below are the simplest places to look.
Look for it in the Vehicle Itself
- In the radio manual, often on a separate code card.
- In the service booklet provided with the car.
- On the radio chassis if the unit was previously removed.
- On a label in the glove compartment.
- Near the boot panel, where some manufacturers place radio labels.
Can the Dealer Get You the Code?
Dealerships can generate your radio code by checking the VIN in their system.
They typically require proof of ownership before sharing the unlock code.
This is the official way to restore access to the factory radio.
Downsides:
- Some imported or older radios may need extra verification.
- You may need to visit the dealer during business hours.
- The lookup is often slower and may require waiting.
- Dealers frequently bill for the code (It may cost more than 100$).
Where to Search for the Serial Num. on your TT
The only thing you'll need to find the corresponding code is your radio's serial number (not part number!).
On all Audi's, you can find it in one of these places:
- Directly on the radio screen (by using some combinations of buttons)
- On the radio unit itself - you'll need to extract it and write down your serial (which is not so hard).
Search for something that looks like: Serial Num., SN, S/N, Serial, Serial Number...
1. Find the S/N on Audi TT's Screen
Unfortunately, on Audi TT radios the serial number is not shown on the screen.
In that case, you'll need to take out the head unit and check the sticker on the side of the radio.
2. How to Find the Serial Number on the Radio Sticker
The serial number is usually printed on a label attached to the radio casing.
Step 1: Turn off the vehicle.
Step 2: After that, remove the dashboard trim.
Step 3: Then release the mounting clips.
Step 4: Carefully pull the radio forward partially (Be careful not to damage the cables that the unit is connected to).
Step 5: Look for the serial number on the rear of the unit.
Step 6: Write down the full S/N carefully and come back to our website so that we can generate your code.
Important: Don't mix the Serial Number from the Part Number!

Now You Have the Code. How to Enter It?
You need to input the radio security code into the system to unlock your Audi's radio.
In the locked unit, the screen usually displays a code prompt.
Based on the radio, use control knob, touchscreen, or radio presets to enter the numbers, then confirm the code to reactivate the audio system.
Try not to make mistakes, because too many wrong attempts can disable your radio temporarily.
It allows a few incorrect tries before showing a LOCKED message.
You can reset the lockout by leaving the radio on for one hour or a set waiting period.
