If factory installed put on radio.The safe sign will appear.There should be a 4 digit code for the radio.Punchin the code using numbers 1-4.Press repeatedly from number 1 till for the fist digit number 2 for the second digit etc.when you have punched the code in the safe sign will appear.Briefly press loud /expert then wait a few seconds your radiio should then display .Look for your favourite channels .If you punch in the code wrong there is a waiting period.First attempt wait 21 seconds ,second attempt1.5 minutes 3rd attempt5.5 minutes...4th attempt22 mins.5th attempt1.5 hrs. If this fails ,disconnect battery and start again

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!

radio may need a radio code to re activate. if SAFE appears on the display then this is the problem.you would need to get a code from a VW dealer.

Blocked? I am guessing that it has something on the display, like"SAFE"? If there is power going to it, and signs of some life...it could be the car's radio alarm. When battery power is lost to the radio, it will trip an alarm. It requires a 4 digit code to work again.
If you have the owner's manual, you can find it in there. If not...
If you pull the radio, DO NOT disconnect any wires, and find the serial number on it, you can call a dealer and get the code for the radio.
Some cars hold down MODE and SCAN and the SAFE should change to 1000. This is where you input the numbers using the up and down to change number value & the first four station buttons to change to next number.
Good Luck.

The radio is in Lock-Out mode. You only get two attempts to enter the code, then it enters Lock-Out mode.
Put the key in ignition and turn on the radio for an hour (maybe a bit more). The radio should reset itself after about an hour and then you can re enter the code.

Hi All, the very same thing happened to me. Cold weather broke my radio and the display screen stayed on with the time and temperature but the radio wouldn't work. I rang Renault & they said I need to come in an get a new radio but I put it off. In the end the problem started affecting my battery and the car wouldn't start. But then when I jump started it, it also started the radio again perfectly. Problem solved!
Hope this helps. Good luck!

If you don't have the radios security code, you can try entering 1111 as some replacement radios were coded with this security code. Your local Audi Dealer may be able to provide the correct security code for your vehicle, if you provide them with your vehicles Identification Number (VIN). This VIN is typically located on the drivers door pillar.

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.

To enter the code on the Wiesbaden Radio: Turn on the radio, SAFE should be displayed.
Push and hold the AM/FM button, then while holding the AM button down, push and hold down the SCAN button. Release the AM/FM and SCAN buttons, and the display should show 1000. Now enter the correct code using the radio pre-set station buttons (1-4). Button 1 changes the first digit in the code "1"000, Button 2 changes the second digit in the code 1"0"00, button 3 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 AM/FM button, then while holding down the AM/FM button, push and hold down the SCAN button. The display will then show SAFE, release the two buttons, and now the radio should play correctly.

If SAFE doesn't show up, then you don't have a secured radio. If yours isn't working you have another problem.
