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.

How do I reset the radio in an Audi tt 2004? The indicator light says "SAFE"


The radio is in safe mode and requires the security code to reactivate it. First check through your service documentation for a credit card sized card that Audi print the code on.

If this is missing the only other way to retrieve the code is

1) Remove the stereo from the dash and retrieve the serial number stamped on the back of the stereo.

2) Contact your Audi dealer with both the serial number and the chassis (VIN no) of your car. You will find the VIN no on your registration document.

3) If you do it this way and have retrieved both of these numbers yourself your Audi dealer will run the numbers and give you the code free of charge.

Hint: Some dealers will attempt to charge for this service but they are not authorized to so. On the original safe code card from Audi it specifically states that if you lose the code your Audi dealer will supply this free of charge. Please ensure to quote this information to the dealer if they attempt to make any service charge.

Hope this helps. Please do rate my answer and thanks for using FixYa.

Instructions to unlock stereo


Turn on the radio. The word "SAFE" appears on the display.

* Press the FM2 and RDS buttons simultaneously and hold them down until "1000" lights up in the display. Release 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 stations buttons 1 - 4 to enter the code number on your Radio Card.( THE RADIO CODE SHOULD BE WITH THE OWNERS MANUAL-??) Use button 1 to enter the first digit of the code number, button 2 to enter the second digit, and so on. Station buttons 5 and 6 cannot be used.

* Once the code is shown in the display, press the FM2 and RDS buttons again simultaneously and hold them down until the word "SAFE" appears on the display. Soon afterwards, a frequency will be displayed.

(If you do not have the "Radio Code", the Audi dealer, or someone, will have to pull the radio out to get the serial number off of the back.)

The radio can now be used again.
