Just bought a replacement cd changer for my '98 A3 with the crappy detla sound system and it was working perfectly for a week. I then chaged some cd's and its since displayed 'CD 00 ERR' when i tray and play it.

It also wont eject the cd cassette and the green eject light isnt on. Ive tried unplugging it and plugging it back in but the same thing happneds. Just wondered if anyone what i can do, hope i havent just wasted 80

Any help much appreciated!
