What is the reason for the creaking sound when turning the steering wheel of an Audi Q3?

[Lawrence]

First, it is necessary to determine whether the sound is coming from inside or outside the car. Here is the relevant information: Inside the car: If the sound comes from inside the steering wheel when turning, this issue is mostly caused by interference from the steering wheel's clock spring. Remove the steering wheel clock spring and apply some grease to see if the sound persists. If it still occurs, the clock spring needs to be replaced, as it is damaged. Outside the car: If the sound comes from outside the car when turning, this issue might be due to a lack of lubrication in the strut mount bearing. Simply open the hood and listen to see if the sound is coming from the top of the strut mount. This will help determine if the sound is from the strut mount bearing. If it is, apply some grease to the bearing. If the sound continues after greasing, the bearing must be replaced.
