- The steering wheel generates grinding noises between the steering wheel and steering column switch module during steering maneuvers See example file in the attachments area: Lenkrad-Schleifgeräusch_SteeringWheel-GrindingNoises.mp4 The plastic cover on the back of the steering wheel is not positioned correctly and may therefore rub against the steering column switch module Please use the following noise files for the damaged part analysis: 1.
