What your Audi serial looks like
14 characters starting with AUZ. Check the capital I against the number 1 carefully.
How to enter the code
Switch the radio on until SAFE then 1000 shows. Use preset buttons 1 to 4 to set each digit (button 1 sets the first digit and so on). When the full code shows, press and hold the two seek arrows (or TP and RDS on older units) together for about two seconds until the radio unlocks.
