Nope - you need the radio removal keys. You should see some small holes or slots near the edge of the faceplate - there are keys that go into them to unlock the radio. A stereo shop will have them - they may even pull the deck for you if you ask nicely. Only takes a few seconds, and it saves you having to buy the keys.

SOURCE: connected jumpers wrong, radio doesnt work now

usually circuits have internal protection for this. Call your dealer and ask the service department if this happens and if there is a reset or simple fix.

What are the steps to enter radio code for Audi A2 2008 Model?


I'm not sure which model you have but these are the instructions for Symphony 1.
I'm not sure if this also applies to Symphony 2 (which has a built in single slot 6 CD changer)

Switch on - display shows SAFE as you indicate
Press and hold TP and RDS buttons at same time until 1000 appears
Release buttons (dont touch again or 1000 will be entered as the code)
Using station select buttons 1 to 4 enter code. Use button 1 to select first digit of security code, button 2 for second digit etc (buttons 5 and 6 cannot be used)
Once code is entered press TP and RDS buttons together and hold until SAFE appears
Release buttons and a radio frequency will appear in the display
Job done

If you accidently enter the wrong code the word SAFE will start flashing. You get ONE more chance to go through this procedure and enter the correct code.
There is a more complicated procedure to go through after this with one hour time delays between attempts

Let me know how you get on!

I dont remember if that year had a theft lock system or not, but I am looking into it. disconnect the negative battery cable for ten minutes and that should get you back to where you can enter the unlock code again and use the radio.

2001 Audi A6 2.7t , my audi symphony radio locked out


You will need the code to get it working. You may need Audi for this. Never disconnect the battery, or the alarm with trip on. Since it is frozen, I would try and remove the fuse, and reinstall it to reset the stereo. Then try the code.
I got lucky in my 2001 VW passat, when the stereo code was needed, but then the next day it started working by itself.

My audi a6 radio has a SAFE message in the screen what it does mean?


Did you disconnect the battery or run it down? This message means you must enter the correct code. If you do not have the code contact your Audi dealer. I'm not sure which model you have but these are the instructions for Symphony 1.
I'm not sure if this also applies to Symphony 2 (which has a built in single slot 6 CD changer)

Switch on - display shows SAFE as you indicate.
Press and hold TP and RDS buttons at same time until 1000 appears.
Release buttons (dont touch again or 1000 will be entered as the code).
Using station select buttons 1 to 4 enter code. Use button 1 to select first digit of security code, button 2 for second digit etc (buttons 5 and 6 cannot be used). So, say the code is 5238, you'd press '1' five times, '2' twice, '3' three times and button '4' eight times.
Once code is entered press TP and RDS buttons together and holde until SAFE appears
Release buttons and a radio frequency will appear in the display.


If you accidently enter the wrong code the word SAFE will start flashing. You get ONE more chance to go through this procedure and enter the correct code.

You could try a laser lens cleaner (the one that looks like a CD with little brushes on it) to see if that'll do it. There's no guarantee that the problem is with the laser eye though. If it is (such as just being dirty or dusty) then this may do it. If not though, that error code may indicate a more permanent failure of the head unit.
