The BMW active steering system utilizes a double planetary gear system located at the base of the steering column to facilitate driver independent steering of the front wheels. The system is intended to offer two principal benefits; a variable steering ratio and stability-enhancing corrective steering actions.

What is BMW variable sport steering?
The variable sport steering increases the steering angle of the front wheels at large steering wheel angles, e.g., in tight curves or when parking. … It also varies the force required to turn the wheels in accordance with the vehicle speed. This results in a sporty steering response.

What does BMW steering angle sensor do?
The steering angle sensor (SAS) determines where the driver wants to steer, matching the steering wheel with the vehicle’s wheels. Located within the steering column, the steering angle sensor always has more than one sensor packaged together in a single unit for redundancy, accuracy, and diagnostics.
What kind of steering does BMW have?
Most BMWs use rack-and-pinion steering. The pinion is the steering shaft and it meets the steering rack at an angle. Turning the steering wheel turns the pinion shaft and the pinion teeth mesh with the rack teeth to move the rack side-to-side.
Does BMW use power steering fluid?
The manufacturer directly recommends Pentosin power steering fluid as the brand’s number one fluid. It was designed with BMW specifications in mind, and it’ll keep your car’s steering system working like a dream. BMW cars since 1990 will need Pentosin CHF-11S, while older ones will require CHF7.
Does BMW have rear-wheel steering?
BMW models have had rear-wheel steering (also known as integral steering) for quite some time now. However, in current applications, the amount of actual steering the rear wheels can do is rather limited.

Why does my BMW make a noise when I turn?
A creaking sound when turning your steering wheel may be nothing more than a sign that your suspension system needs lubrication, but it may be a sign of something more serious, including tie rod damage, power steering rack damage, or a failing strut/shock.
How many times can a steering wheel turn?
A steering wheel can typically turn between about 972 and 1152 degrees, or about 2.7 to 3.2 full rotations. The actual amount that your wheel can turn will depend on your car and the age of your vehicle. However, it’s not recommended that you turn your steering wheel all the way.
What is active steering on BMW X5?
The Active Steering system adjusts both steering ratio and steering force in relation to driving speed. At low to medium speeds, a small turn of the steering wheel translates into a big turn of the front wheels. You enjoy more agility in city driving, quicker turns on twisting roads, and easier parking maneuvers.
Does BMW 5 Series have rear-wheel steering?
BMW 5 Series Performance Features Integral Active Steering: Adds rear-wheel active steering, so the rear wheels steer in the same direction as the front wheels at high speeds for better stability. At low speeds, the rear wheels steer in the opposite direction from the front wheels for a tighter turning radius.
What is active steering alignment?
In normal steering, the car wheel turns at the same angle, whether at low or high speed. With active steering, you don’t have to turn the steering much to turn for the same angle at low speed. At a higher speed, you have to turn a bit more. Essentially it adjusts to the speed.
What is Servotronic on BMW?
The system is designed to maximise the comfort for the driver, whether it be cruising on the motorway, or parking in a tight space. It achieves this by an electromagnetic valve which accurately controls the amount of force applied by the steering hydraulics when the driver is turning the wheel.
