So my battery went dead on my 2000 a6 the stereo went into safe mode does any know the code ? That would be great if someone would tell me the code ?

 

Codes are unique to each head unit or it would defeat the purpose. Go to the dealer - they can look it up for a fee.

 

Or buy a new / refurb radio. ECS has some and you probably spend less getting a "new" radio then asking the dealer to read the code out.
Dealer wants around a 100 bucks to read the code out.. a refurbished radio costs 40 bucks + shipping - you go figure what you would like to do

Also your radio if it was never replaced is now 11 years old, it probably has a few signs of age (CD player skipping, tape not working, fading display, ***** having a sluggish response, or poor output). I recommend getting a new or refurbished radio with a new code but is of course your choice.

 

Is my radio the only one that doesn't require a code if the battery dies or is unhooked for any period of time?

 

Well I found the code today in the manual but last night I was trying different code and now it lock up when I press the rbfs and p scan button now it still say safe before when I press the two button it let me put a code in now nothing any idea ?

 

Unhook the battery terminals again ... to see if it reset and let you input the right code.

I saw somewhere that you have to wait for a day or two so to allow you to re-enter code if you're not successful by entered wrong codes.

 

All you need to do is leave the key turned on in the ignition for an hour or ^^^so without screwing with anything, and it'll buy you three more attempts.

 

For every 2 failed attempts at entering the SAFE code you have to wait 2 hours of operation time before you can try again. If you turn off the car, remove the key and then turn the radio back on before you open the door the radio will remain on without needing to leave the keys in the ignition.

 

It been about 3 days now I try disconnect the battery and that did not work the manual say I need to wait one hour before I can have a second try also try that leaving the key in the ignition with the stereo on for over 1 hr that did not work , if I try my car off and take the key out the stereo does not come on the key have to be in the ignition any idea on what else I could do ?

 

This morning I turn the car off and I was able to take the key out and the radio turn on into safe mode I am going to leave in for 2 hours and hopefully that works
