To reset the Audi radio code when it displays "SAFE 2," you'll need to enter the correct security code. First, turn on the ignition but keep the radio off. Then, hold down the "TP" and "RDS" buttons simultaneously until "SAFE" appears. After that, use the radio preset buttons to enter the code, followed by pressing the "TP" button to confirm. If you don't have the code, you may need to consult your owner's manual or contact a dealer for assistance.
If your radio is locked and needs to be unlocked, it would require a security code versus a radio code.
I just purchased a 2009 Jetta SE and the radio was in SAFE 2 mode. The dealer tried the radio code but could not get the radio to a point to enter it. I read a number of threads and tried many suggestions, leave the car in the Aux mode for an hour, hold down the seek and mode buttons etc. Finally I disconnected the battery waited a few moments and re-connected. I figured maybe this would show me the screen to enter the code but instead the radio booted up with no code and works fine. The dealer suggested I return when the service dept was open, none of the sales people had a clue.
The radio code for a 1997 Audi A8 Quattro with an Audi Delta CC radio system is a unique security code typically found in the vehicle's owner manual or on a card provided with the original documentation. If you cannot find it, you may need to contact an Audi dealership or a qualified automotive technician, who can retrieve the code using the radio's serial number. Always ensure you have the necessary vehicle identification when seeking assistance.

unless you have the 4 digit number you cant...a visit to Audi is the only way
You need the serial number from the side of the radio and also the VIN number. You call an Audi dealership and give them the two numbers and for a $30.00 fee they will give you the radio code to take the radio off of "safe" mode. Lewis Powell
your code is unique to your car... you'd have to get it from the dealer if you lost it.
You need your operator's folder. In there is a booklet about the radio. it will have a code you need to enter to get the radio out of "safe" mode. the code is unique to each radio and car.

If you can't find it, look for a card or sticker within the glove compartment or the trunk. Alternatively, you can contact an Audi dealership with your vehicle identification number (VIN) for assistance, or use online services that may offer code retrieval based on the radio's serial number.
