Every time you drive in your BMW, you move the wheel. As a result, you will immediately recognize a screeching sound when it occurs.

Common causes of this include:
The main power steering system issues that could hinder your ability to turn the steering wheel are as follows:
Low power steering fluid: Your power steering relies on the force that the power steering fluid exerts against the piston inside the rack and pinion to work properly. The force that can be given to the piston decreases as the amount of fluid in the power steering system decreases. When this occurs, the power steering system is less helpful in steering, and the driver must now exert more force to turn the wheel.
Damaged power steering belt: The power steering belt drives the power steering system’s movement. Like any other belt in your car, a system’s operation begins and ends with its belt. One of your car’s most vulnerable parts are the belts. More than most other automotive parts, they are more prone to cracking, snapping, and loosing. You won’t be able to turn the steering wheel easily if your power steering belt breaks since your power steering system won’t be able to function.
The fundamental component of your steering assembly, the steering rack, which is a part of the rack and pinion, functions in combination with the power steering system. Over time and with wear and tear, steering racks can become worn out and destroyed, which makes it much more difficult to steer your car. If your car is only difficult to steer when you first start it, its steering rack is probably damaged. When the car warms up and the rack gets hot and well-lubricated, this issue frequently disappears.
Low tire pressure: Although a defective or dysfunctional power steering system is nearly always the source of a heavy steering wheel, low tire pressure in one or more of your tires can also be the culprit.

BMW’s steering is far too heavy. Even without power steering, they are greater than the effort. It is hand- and finger-wearing under boost, not athletic.
Road feedback is provided by a decent steering system. It’s not necessary for a competent steering system to make you feel like you’re controlling a 50-ton truck without power steering.
You can attempt to tell yourself that your steering is excellent, but let’s face it, most BMW vehicles fall short of expectations.
Why does Servotronic steering come as standard in all other luxury vehicles? since it is effective. since it offers accurate road feedback. mostly because it makes driving fun.
Simply drain your car’s power steering fluid to instantly transform it into a BMW if you want the overly heavy steering system.
#1: Insufficient power steering fluid
Lack of power steering fluid in the system is arguably the most frequent reason of a stiff steering wheel when turning. This typically happens when fluid leaks from the pressured hose area. The hose may occasionally develop cracks or just become slack, allowing the fluid to spill.
The less power steering fluid you have in the system, the harder it will be to turn the steering wheel because this fluid is required to pressurize the system and lubricate the pump.
Even though the car might be able to be driven, if the leak is not fixed, ultimately your power steering pump will break down, necessitating an expensive replacement. Continue reading if a cursory inspection reveals that your power steering fluid is full.
What might result in stiff steering?
Heavy steering is when your car’s steering wheel is rigid and is challenging to turn. Numerous factors, including low fluid oil, low tire pressure, and improper tire alignment, might contribute to this. Heavy steering makes it more challenging to control your car, while a rigid, unresponsive steering wheel might reduce the car’s performance. Consider yourself to be having steering issues?

How is steering handled by BMW?
The main components of the BMW active steering system are an electric actuation motor, a double planetary gear system in the steering column, and a power-assisted rack and pinion steering gear.
The double planetary gear system consists of two planetary gears, a rotating housing, an output sun gear connected to the steering pinion, an input sun gear attached to the driver’s steering wheel, and two planetary gears. The driver’s steer inputs are translated with a net 1:1 ratio if the housing is kept stationary, from the input sun gear through the planetary gears (which share a common lay shaft) to the output sun gear. In other words, if the planetary gear housing is not moved, conventional steering is still possible. In the event that the active steering system fails, this feature offers a way to maneuver the car.
A motor and worm gear can rotate the planetary gear housing, which has exterior gear teeth. The output sun gear can rotate independently of the position of the input sun gear by adjusting the housing’s position. Driving the planetary gear housing, for example, will cause the steering pinion to rotate if the driver were to keep the steering wheel (and subsequently the input sun gear) immobile (and therefore a steering action at the front wheels). The active steering ECU can create a changing steering ratio or produce steering motions independently of the driver by adjusting the location of the planetary gear housing.
Is the steering on a BMW hydraulic?
A sealed piston divides the steering gear’s internal cavity into two chambers with the aid of hydraulic power. By delivering pressured hydraulic fluid to one side of this piston, which is coupled to a rack, fluid from the other side can return, providing power assistance. A valve is fastened to the pinion shaft in order to maintain control of the hydraulic fluid.
Although hydraulic power steering has been improved over many years to the point that it offers a natural, progressive steering sensation at all speeds, there are a few drawbacks:
lower fuel efficiency
Fuel consumption rises as a result of hydraulic power steering since it draws energy from the engine.
Greater Weight of the Power Steering System
The hydraulic system is heavier and takes up more space than Electric Power Steering (EPS) since it has more components.
Power steering upkeep
Again, the hydraulic system requires more maintenance than EPS and is more prone to failures than EPS due to its more basic structure and design, as we’ve discovered at our BMW repair center.
Is the steering heavy on a BMW?
Although it is heavier than the majority of other automobiles, I don’t find the weight to be an issue. It would be simpler to palm the wheel if there was a bit more boost during maneuvers, but if you drive a car with manual steering, you might stop griping about yours.
What can I do about my stiff steering wheel?
- Verify the tire pressure on your car.
- Check the fluid level and condition of the power steering.
- Verify the power steering unit’s pulley.
- Examine the power steering system.
- Verify the front end components.
When did BMW make the transition to electric steering?
Beginning with the E85 Z4 models in 2004, electric power steering has been a feature on all new models thereafter.
How much does a stiff steering wheel repair cost?
The cost to repair a damaged component, your vehicle’s make and model, and the auto shop you take your car to all have a role in how much the repair will cost. For power steering problems, you should budget $250 to $350 on average.
How can I tell whether the power steering in my BMW is electric?
Okay, this might sound like a newbie question because, sadly, I have no idea what it even means. However, I’ve been considering obtaining an intake for my e90, and the majority of manufacturers provide two models: one for cars with active steering and the other for those without. So how do I determine if I own it or not? 2006 BMW 330i 6-speed vehicle
When parked, if your steering wheel can be turned from full left to full right in just two turns, you have active steering.
You don’t have it if one of the caps beneath the hood has green on it, but you do if it’s complete black. When viewed from the front, the cap should be to the right of the engine.
Ask for a quote on a front wheel alignment for your specific vehicle at your dealer. You have AS if the advertised price is more than 10 times higher than what a human would pay for an alignment task.
Does anyone know WHY alignments for AS cars cost so much? Although I haven’t received one yet, I’m dreading it.
When should a BMW power steering fluid change be made?
To start, you should be aware that you should change your power steering fluid every 30,000 miles, but you should read your owners handbook to be certain of your car’s make and model.
Is power steering fluid required for BMW?
You shouldn’t just pour any fluid into your automobile, despite the fact that many power steering fluid products may seem the same. These fluids perform far too crucial of a role for one to simply acquire one without doing any research. Power steering fluid’s function is to lubricate the steering mechanism and guarantee that the connection between the steering wheel and the tires is secure and functional. Your tires move the wheel precisely in the direction you want them to go based on how you are steering, correct? Only fluid used for power steering makes this possible. You must have new power steering fluid that is compatible with the design of your BMW’s power steering system in order to drive your car safely.
Because the mechanical properties of steering systems in cars can vary so greatly, different components are required for maintaining them. Chemical characteristics of power steering fluid can vary widely, and different products have different viscosities and additives. Each automaker specifies a particular kind of lubricant for its vehicles, and this is done for a good reason. If you use the incorrect fluid, you run the risk of doing serious harm to your steering system, pump, and even your ability to steer, which is dangerous for your health. Because of this, it’s crucial that you maintain the proper power steering fluid in your vehicle.
