Question about 1993 Audi 100
Gamma model radio. I had gotten it into code input mode previous so I could try code 1111. i have waited more than an hour between attempts. I am wondering if i should just disconnect the battery for a while.
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.

If you don't want to spend the 135, find out the name of the dealer who origonally sold the car when new. They should have the code on file form the pre inspection that they did. It is a myth that there is a code inside the trunk or on the radio, so don't waste your time looking.

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.

I had the exact same problem on my 1998 Audi A4 Quattro Sedan I just purchased. I read a couple of other posts that said to try looking for the radio code in the spare tire compartment in the trunk. Sure enough on the right hand side of the compartment was a information label and on it someone had written the code 1174 in pen. I then left the key in the ignition and the radio on for an hour. Then I pushed the DX and FM1/2 button and the same time until the "1000" number appeared on the display. Then I pushed in the code 1174 using the 1 - 4 tuner buttons. For example the number 1 key I pushed until the number 1 appeared. Then pushed button number 2 until the number 1 appeared, pushed button 3 until the number 7 appeared and button 4 until number 4 appeared. After I had the code 1174 on the display, you again push the DX and FM1/2 button at the same time and the radio unlocked and worked perfectly. I hope that this helps. I have the Delta (Bose) AM/FM Cassette radio in my car. Good Luck!!

sorry to say, you will need to take it in, it needs to be hooked up to their computer to reset and have it start up poperly. It just like a pc when it crash it will try to start in safe mode until you select "Normal" start up
