Hello all. I have a 2004 A6 3.0 Quattro Avant. It has the Symphony II stereo with an internal 6-disc cd changer. Currently, I cannot listen to any cd's because the stereo is displaying "Error 5" and then switching to the "external disc changer", which of course I do not have. My stereo display just reads "Track 99". I've tried pressing the CD button to switch back to the internal changer like the manual says, but it just shoots the Error 5 and switches back to Trackk 99 quickly. I can't even eject, load, or scroll through the CDs that are in there. I've also tried disconnecting battery in hopes of resetting the stereo, but to no avail.

If anybody can help it would be greatly appreciated. Also, of note, a few months back I added an auxiliary input cord that attaches to the SAT connection behind the stereo. CD changer worked fine after that, so I don't think this is related.

 

Type "error code 5 audi radio" in the search field. It'll pull up a previous thread or call Audi-USA 1-800-822-2834.

 

Thanks. I tried searching before but couldn't find anything. Let me try again.
