Check which area of the steering column the noises occur in. Do the noises tend to occur at the bottom in the driver footwell or do they tend to occur in the area of the steering column switch module \(MRSM/SCCM\)? If the noises occur in the area of the MRSM/SCCM, work through the following points: \- Loosen screws of the MRSM/SCCM and steering wheel, re\-align the MRSM/SCCM, and re\-fasten the screws \(see WIS\). Sometimes there is stress at the MRSM/SCCM and noises occur. \- If noises continue to occur, swap the MRSM/SCCM into a vehicle without any \(noise\) complaints. \- If the noises occur with the MRSM/SCCM complained about when it is in the vehicle without a complaint \(donor vehicle\), the MRSM/SCCM can be replaced. \- If noises also occur in the customer vehicle with the MRSM/SCCM from the reference vehicle, the MRSM/SCCM is not the cause and must not be replaced. Notes: \- When installing the MRSM/SCCM, make sure that no damage occurs\! \- Only disassemble and mount all component parts in the "straight\-ahead position" \(see also WIS\). \- Please refer to this LI in the "Notes" section of the warranty claim\!
