Audi A4 Quattro CD player malfunction, not playing on Audi A4 Quattro

Some Audi A4 Quattro owners report experiencing issues with their CD player not functioning properly, often indicated by the error message "cd 5 error 3," which may suggest a jammed CD. Others find that the CD changer fails to recognize the audio CD, reverting to the DVD player instead. Additionally, problems such as a dirty or misaligned laser head, or a drive malfunction where the CD does not spin correctly, can contribute to this issue. In some cases, a jammed CD in the changer may require removal and proper reinsertion to resolve the malfunction. Furthermore, owners with auxiliary connections, like an AUX lead linked to the CD changer input, report that these can interfere with the CD player's operation. Troubleshooting efforts, including checking cables and fuses or testing known working radios, have yielded no success for some users. If problems persist, it is advisable to inspect the CD player for obstructions, ensure correct CD insertion, and check for loose connections, or seek assistance from a certified technician for further evaluation.
