Make the noise reproducible
Describe the setting
Write down whether it occurs while parking, in left turns, right turns or both. Note whether braking changes it, whether it began after wheel/brake work and whether the car is cold or warm.
Keep the symptoms separate
Report vibration, pulling, warning lights or a change in braking independently of the ticking. A noise bulletin is not evidence that those other symptoms are harmless.
What the bulletin supports
B34 05 15 describes a workshop isolation procedure at the disc/hub interface and a specific corrective treatment after confirmation. It does not support greasing the interface, sanding the hub indiscriminately or replacing unrelated parts on sound alone.

Ask for a finding, not a guess
Give the shop the bulletin reference and your observations. Ask what was reproduced and what distinguishes this interface noise from a wheel, brake or suspension fault. Keep the answer with the repair history.
