Press the p.scan and RBDS buttons at the same time, when done correctly the display should change from safe to 1000, then use the 1234 buttons under the display to enter the code.

You may have the wrong code it should be a 4 digit code.

IMPORTANT NOTE:
You must have the security anti-theft code for your Audi 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 2001 Audi A6 radio is:
1. Push simultaneous "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 push again simultaneous "SCAN" and "RDS" keys for 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 for use!

Entering Anti-theft Code

The following is the procedure to re-activate the radio if the display shows "SAFE". It is important that the procedure be followed in the correct order.

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.
7. If you lose your radio code, contact your Audi dealer.

Note: Some European market Concert radios have a TP button instead of the FM2 button, so the description above with those units would require pressing the TP and the RDS buttons simultaneously.

That indicates you need to enter the radio reset code which came with the car. Or see you dealer.

Please rate my response. Thanks!

if it is the radio saying safe, it requires the radio code to be entered

Your best bet is to call a dealer. There's no reason why the service department can't give you this information for free. Make sure you write it down ( I tend to email myself these things) and keep it in the car. If you have the manual, write in there as well. You'll need it for how to enter the code.

Best,

hold rbds and pscan till you see numbers then use the radio memory buttons to control the number you want to put in after the numbers are put in hold rbds pscan again till u see it says safe and radio works.

I just posted a solution for this problem. It comes straight from the radio manual. The dealer should have told you this. If you want him to do it he'll charge money for his time. IF YOU LOST YOUR CODE. THE DEALER CAN HELP YOU OR IF YOU HAVE YOUR 4 DIGIT CODE:

can anyone tell me where the fuel filter is located on the 2001 audi A-6
