Audi Repair: Audi A4 Stereo, 4 digits, radio code

Question
Hi Greg, I left the lights on in the car and killed the battery.  I jumped the car and all is good except that the stereo won't play(cd or radio) it says "CD in  SAFE".  Any thoughts on how I might reset it?  Thanks!

Answer
hello ,
You need radio code #. it's 4 digits, ( most of the time it's in radio manual) if you don't have it , any dealer will get it for you or I can get it for you.
To get the code you will have to give vin# and radio auz #
The auz # is on the side of the radio , so radio has to come out. If you go to the dealer they will charge you.
good luck                pltech
