Inputted incorrect radio code and now the digital display says code waiting. I now have the correct radio code - now what do I do?

The radio should have a serial number on the unit which also can be given to the Audi dealer and checked in their data base of radio security codes. The serial number will start with AUZ, one radio serial number for example is AUZ1Z9A1965412.
First you must turn on the radio. Then simultaneously press the FM1 and the AM buttons at the same time, and hold them down until "1000" lights up in the display. Use station preset buttons 1 to 4 to input the radio code.
If the code starts with "1", you don't need to enter this digit, move on and just use buttons 2, 3, and 4 because the "1" will already be displayed. If the code starts with "0" then press button 1 once to go change the "1" to a "0". Press button 2 as many times as the second digit of your code. Use button 3 for the third digit and button 4 for the fourth digit.
Once the correct code is shown on the display, you must once again press the FM1 and the AM buttons simultaneously and hold both of them down until the word "SAFE" appears in the frequency display. Then release the buttons. You will now have a radio frequency displayed and the radio has been unlocked. If you incorrectly enter the code twice in a row, you will have to turn the radio off and wait about an hour before you can try to enter the code again.

If you've entered a bad code a couple times, you need to wait an hour while the radio and ignition are on. Then, turn on the radio, SAFE should be displayed. Then Press the FM1 button and hold it down, then while holding down the FM1 button, press and hold the AM buttons so that both buttons are held down simultaneously. Release the buttons. Now enter the correct code using the radio pre-set station buttons (one through 4). Button 1 changes the first digit in the code "1"000, Button "two" changes the second digit in the code 1"0" "three" 00, button changes the third digit, button 4 changes the last digit in the code. In most cases the first digit is a 1 and won't need to be changed. You push each pre-set station button multiple times to step through the digits (1-9) to get the correct code displayed.
Code 1246 would entered by pushing button "2" two times, pushing button 3 four times, and pushing button 4, six times.

After entering the correct security code, push and hold down the FM1 and AM button simultaneously as before until SAFE is displayed, then release the 2 buttons, and now the radio should now work.

Please check the information that came along with the owner's manual. It should be printed on a card that comes with those booklets. I assume you've already done that though. I've attached the procedure for entering the code below. Let me know if you have any trouble with it.

If the radio is disconnected from the power supply it is not ready for operation when reconnected. After switching on the ignition and the radio the word "CODE" appears on the display and the letter "C" flashes.

NOTE: The five-digit code number for this radio is printed on the CODE CARD which you were given.

Enter the code number with station buttons, e.g. number 1, station button 1.

After entering the first digit the word "CODE" disappears and the digit entered is displayed followed by 4 dashes. The next digit to be entered flashes. After all 5 digits are entered, the first digit flashes again. In this state the code number can be written over repeatedly. A correction can be made only by reentering the entire code number.
Confirming the code number: Press seek-UP/seek-DOWN or SCAN button. The radio switches on automatically and displays the station or frequency stored for station button 1.

If the wrong code number has been entered and confirmed, the word "CODE" appears on the display again. After the code has been entered three times incorrectly the word "WAIT" appears on the display and the radio is disabled for approx. 10 min .

NOTE: The waiting time continues to run only when the radio is switched on.

After expiration of the waiting time the word "CODE" appears on the display again and the correct code number can be entered. After 3 more incorrect entries the radio is again disabled for 10 min . After 3 more incorrect entries (a total of 9 incorrect entries) the waiting time is increased to 60 min . After 3 more incorrect entries the radio locks up again for 60 min .

maybe this will help.....
the following steps must be carried out in the correct order:

• Turn on the radio - the word "SAFE" appears in the display.

Press the FM 1 and AM buttons simultaneously and hold them down until "1000" lights up in the display. Release the buttons! Do not, under any circumstances, continue holding them down or press them once again. This would cause the radio to consider the number "1000" to be the input code number.

• Use station buttons 1 to 4 to input the code number on your Radio Card. Use button 1 to input the first digit of the code number, button 2 to input the second digit, and so on.

For technical reasons, the first digit can only be a 1 or left blank. The following three digits, however, may be any number from 1 to 9 .

• Once the code is shown on the display, press the FM 1 and AM buttons again simultaneously and hold them down until the word "SAFE" appears in the frequency display. Release buttons! Soon afterward, a frequency will be displayed.
• Should you inadvertently input the incorrect code number in attempting to release the electronic lock-up, the word "SAFE" will appear in the display - first blinking and then continuous.
  
  You can now repeat the entire canceling procedure once. The number of attempts will be shown in the display.
  
  If you input another incorrect number, your radio will be locked up for approximately one hour . The radio will not play. Leave the radio switched on. After an hour, the display with the number of attempts goes out and you can cancel the electronic lock-up as described above.
  
  This cycle - two attempts, one hour lock-up still applies.

Best to you.

Hello, you will need to enter your radio unlock code using these instructions.

1. Press SEEK DOWN, SEEK UP, TUNE DOWN, or TUNE UP. The radio display should show 0000.
2. PRESS SEEK DOWN to set the first digit.
3. Press SEEK UP to set the second digit.
4. Press TUNE DOWN to set the third digit.
5. Press TUNE UP to set the fourth digit.
6. If the code was entered correctly, the radio will display SEC (SECURE). The theft deterrent system for the radio is now active and normal operation may be resumed. If the code was entered incorrectly, the radio will display Err for 5 seconds and the LOC (LOCKED) will be displayed again. If LOC is displayed, repeat 1-6.
7. If the correct code is not entered in 8 attempts, follow the next steps:
7.1. Turn ignition to ACC position. 7.2. Turn radio power switch OFF. 7.3. Wait one hour before repeating steps 1 through 7.

Another three incorrect entries lock up the radio for another 60 min. The waiting time runs only when the radio is switched on.

Hello,

There is a trick to the procedure. You have to turn the key to position 1 or the first stop on the ignition. Turn on the radio and wait between 2.0 to 3.0 hours for the radio to reset and ask for the code. From the owners manual. My 97 takes between 2:25 and 2.5 hours to reset. Every radio is different.

To enter the code:

After installation or when the set has been disconnected from power, the set displays "codE" when it is switched on.
Enter the 4-digit code using the preset buttons. If the correct code is entered, "on" is displayed and the set is ready to use.
If you enter an incorrect code you must enter the correct code again from the beginning.

Incorrect code

If an incorrect code has been entered "rPt" is displayed. Enter the correct code.
After three unsuccessful coding attempts the set will lock and remain locked for two hours.
"OFF" is displayed.

During this waiting period:

the battery must be connected
the ignition key must be turned to position I
the unit must be turned on
Make sure the headlights are turned off to help prevent battery drain (please refer to page 2:6 for information on turning the headlights off). Enter the code again once this time has elapsed.

Goodluck!
Ryan

leave the radio on for a few days, with the wait displaying, it will display CODE after a few days, 2 - 3 days, then enter the correct code , everytime u enter a wrong code the time increases.

if you can remove the radio and take down the radio chassis number i can generate the four figure code,but i need the RADIO chassis number and not the car one
