What causes the clicking sound when turning the steering wheel in an A4L?

[TaliaFitz]

The reasons for the clicking sound when turning the steering wheel in an A4L are: 1. Sound produced when the turn signal returns to position; 2. Abnormal noise from the steering column dust cover; 3. Abnormal noise coming from the steering wheel; 4. Abnormal noise from the shock absorber plane bearing; 5. Abnormal noise from the stabilizer bar. If the clicking sound is caused by friction between the steering column and the floor mat, it is mainly because the aftermarket floor mat installed in the car is too large (such as a full-coverage mat) and comes into direct contact with the steering column. Friction occurs as the steering column moves, so adjusting the position of the floor mat or replacing it can resolve the issue. If the abnormal noise comes from below the steering wheel, it might be caused by the steering column dust cover. Lack of lubrication in the dust cover can lead to friction sounds. In this case, the owner only needs to apply some grease inside the dust cover, and the abnormal noise will disappear.
