the creacking door sound is most likley lack of grease in a ball joint or tie rod...after you dissconnect a battery in an audi you need to follow the owners manual for setting up the radio...lost the memory!

Suggested Repair

After a battery disconnect, follow the Audi owner's manual radio setup procedure to restore CD changer communication. For the driver's-side creak when braking, accelerating, or hitting bumps, grease the ball joint or tie rod.

Conversation Summary

A 1999 Audi A4 owner reported that after a battery replacement the CD changer no longer communicates with the radio and shows a no CDC error, while the cassette and radio stations still work. They also hear a creaking noise from the driver's side when braking, accelerating, or hitting bumps. The expert said the noise is most likely from a dry ball joint or tie rod and that the radio must be set up per the owner's manual after battery disconnection because its memory was lost.
