IMPORTANT NOTE:
You must have the security anti-theft code for your Audi Concert radio from the car manufacturer, or from an Audi dealer!

You can find the radio code at: http://www.radio-code.co.uk/

The sequence of programming for a 2002 Audi TT Concert radio is:
1. Simultaneously push "SCAN" and "RDS" keys until on the screen will appear "1000" displayed.
2. Release keys. No more push on "SCAN" and "RDS" keys because otherwise number "1000" will be considered as first safe code attempt.
For example: we have the security code "5079". Then:
3. By the no.# 1 key you will set up the first safe code digit. Push 5 times on the no.# 1 button. The "5" number will be setted.
4. By the no.# 2 key you will set up the second safe code digit. Push 10 times on the no.# 2 button. The "0" number will be setted.
5. By the no.# 3 key you will set up the third safe code digit. Push 7 times on the no.# 3 button. The "7" number will be setted.
6. By the no.# 4 key you will set up the four-th safe code digit. Push 9 times on the no.# 4 button. The "9" number will be setted.
7. Then simultaneously push again "SCAN" and "RDS" keys to confirm this safe code. On the screen will be displayed "SAFE" notice. Release keys! For few seconds a radio frequence will be displayed.
The radio is now ready to use!

1. Turn on radio. The radio display shows "SAFE".
2. Press the FM2 and RDS buttons simultaneously and hold until "1000" shows on the display. Release the buttons. Do NOT press these buttons again, otherwise the radio will consider "1000" to be the code.
3. Use Preset buttons 1 ... 4 to enter the four-digit code number from your radio card. Preset button 1 corresponds to the first digit, Preset button 2 corresponds to the second digit, etc. Each press of the button increments the number by 1.
4. Once the code shown on the display is correct, press the FM2 and RDS buttons simultaneously and hold until the word "SAFE" appears in the display, then release the buttons.
5. The radio should unlock and be usable shortly afterwards.
6. If an incorrect code is entered, the word "SAFE" appears, first flashing and then continuously. You can repeat the above steps to unlock the radio once more, the number of attempts will be shown in the display. If an incorrect code is entered again, you radio will be locked for about one hour. After one hour - the radio must stay on and the key must remain in the ignition lock - if the display goes out, the you can repeat the above procedure to unlock again. The cycle - two attempts, one hour lock-up - still applies.

Yes, there is a second fuse on the back of the radio, (10A - red colour), but you have to pull the unit to check & change it. This is only course of action. You need special Audi Concert radio extracting tools, (two radio keys).

what you may do is....turn the car off and then turn the radio on.. don't do anything with the car for one hour. meaning leave the radio on for one full hour and the radio itself will reset itself. the radio will turn off.turn the radio on..on the radio it will say... BOSE..press and hold both button RDS and FM2 until the radio resets to 0000 ..then enter in your code..once you enter your code press and hold the two buttons again..this will work...

you will need to get the serial number off of the radio and with the vin contact the dealership they should help.

good luck

It is highly likely that the radio will have lost its security code whilst being disconnected from its power supply (your battery).

Any local dealer will re enter your code for you for a small charge unless you have the code stored in your radio user guide in which case you can re-enter the code yourself.
