Some Mercedes-Benz 300SE owners report experiencing a loud noise when turning the steering wheel, often attributed to a power steering fluid leak. This issue can lead to low power steering fluid levels, which may cause a whining noise during turns. Common causes of this noise include low or contaminated power steering fluid, a worn or loose power steering belt, or a failing power steering pump. To prevent further noise and potential damage to the power steering system, it is crucial for owners to identify and repair the source of the leak promptly. It is advisable to have the issue inspected and repaired by a qualified mechanic to ensure the vehicle's power steering system functions properly and maintains overall safety on the road.
