Here are the causes and solutions for abnormal noise in BMW steering gears: 1. Friction between the steering column and floor mats: The newly installed floor mats are too large and directly contact the steering column, causing friction as the steering column rotates. Solution: Adjust the position of the floor mats or replace them. 2. Contaminated power steering fluid: If the power steering fluid is too dirty, it will increase the pressure in the power steering system, leading to abnormal noise from the power steering pump. Additionally, when the hydraulic oil becomes dirty or deteriorates, the formed oil film cannot meet normal working strength, and the lubricating performance of the deteriorated hydraulic oil decreases, intensifying friction between metal parts and reducing their service life. Solution: Regularly replace the power steering fluid.

Does a speed limit camera flash mean you've been photographed?

If a speed limit camera flashes once, it means you have been photographed. Each flash from an electronic eye represents one capture. The types of monitoring cameras on highways are as follows: 1. Ordinary cameras: One type is the ordinary camera, specifically designed to capture violations such as driving over the line or illegally using the emergency lane. 2. Speed detection cameras: The other type is specifically for capturing speeding. When a vehicle runs a red light or exceeds the speed limit, it will be photographed.
