Hey listers, I have a 97 A4 with the 8 pin 6-disc changer that is reading CD ER 00 and will not play. I have tried ejecting the cartridge and the changer won't respond. I tried unplugging the changer and still no luck. Any suggestions? Doug Hill 97 A4 2.8 quattro 87 4kcs quattro (gone but not forgotten)
