Lack of power steering fluid in the system is the most frequent reason of a stiff steering wheel. If there is a fluid leak from the pressurized hose location, this problem may develop. The issue can be temporarily resolved by adding more fluid to the power steering tank, but the leak needs to be fixed.

#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.
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.
Screaming Sounds
You turn the wheel of your BMW every time you drive, so if you hear a screeching sound suddenly while turning, you will know right once that there is a problem with the steering. The steering belt is either loose or worn down, which causes this noise. The belt must be securely fastened and thoroughly greased in order for the wheel to rotate. If your BMW is making a loud screeching or whining noise, have the belt replaced or tightened by a service specialist.
What causes the stiffness in my steering wheel?
The most frequent reason for a stiff steering wheel is when your system’s power steering fluid level is low. This frequently occurs when the pressurized hose section of the system develops a leak. The majority of the time, the fluid leak is caused by a fractured or loose hose.
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.
Are there steering locks on BMWs?
After you’ve shut off the ignition, all it takes to lock your steering wheel is a fast turn in one direction. To know if the wheel is locked, you should hear a loud click. Keep in mind not to wiggle or jam the wheel once it has been secured! Later on, you can have greater difficulty unlocking it.
How do I solve the steering lock on my BMW?
Start the engine by placing your key in the ignition and turning the steering wheel in the proper direction. Turn the wheel in the opposite way and repeat the process described above if the wheel won’t unlock and/or the engine won’t start. You should now be able to release your steering wheel
BMW uses hydraulic steering, right?
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 rack on a BMW repairable?
These steering racks, which were installed in all BMW F20 (1 & 2-series) and F30 (3 & 4-series) vehicles, are now repairable.
The symptom: When driving over potholes, uneven road surfaces, or sunken drain covers, the right side of the car makes a metallic “clunk” or “knock.”
Numerous organizations have made a variety of repair attempts throughout the years, all claiming to have resolved this infamous problem. The same irritating clunk has been seen even after users installed steering racks that had been repaired or utilized or after they employed improved bolts.
These BMW vehicles are affected by this problem:
- BMW F20 and F21 1 Series.
- BMW 2 Series F22 and F23
- BMW F30, F31, and F34 models.
- BMW F32, F33, and F36 models.
- BMW X3 F25.
The problem is brought on by excessive motion between the steering rack’s internal gears and the electric power steering motor. Before, the only solution to this problem was to install a brand-new replacement BMW steering rack, which cost roughly PS 2200 to install and configure.
Your present steering rack will be repaired using only original BMW parts; the repair will cost PS299 inclusive of VAT. This is a significant cost savings that equates to about 13.5% of a full steering rack replacement. Our repair is permanent, and the replacement parts are upgraded and revised (they are different to the parts that were once fitted at the factory).
To far, this repair has completely removed the terrible “knock” from all automobiles. You won’t have to put up with this problem any longer because all necessary maintenance parts are always kept on hand.

Why is electric power steering stiff?
Electric steering: just one side has stiff steering The most common solution is to calibrate the steering system using a scan tool if electric steering is stiff only in one direction due to this common cause.
BMW’s electronic steering uses fluid, right?
BMWs are high-end European automobiles, thus any power steering fluid won’t do. When you use high-quality fluid that matches the design of your BMW, you can truly sense the difference in driving when compared to others that have been tuned expressly for fancy automobiles like these. There are a few options available for your BMW power steering fluid, but if you want to keep your beautiful BMW in peak condition, you shouldn’t go too far from them. The best power steering fluids for a vehicle like this are listed below:
- Power steering fluid with pentosin. Pentosin power steering fluid is the brand’s top fluid, according to the manufacturer. It keeps your car’s steering system operating like a dream and was created with BMW requirements in mind. Pentosin CHF-11S is required for BMW vehicles made after 1990, while CHF7.1 is needed for earlier models.
- Automatic transmission fluid, Dexron III. If your BMW can accept ATF, this is next to Pentosin in terms of fluid quality. Dexron is a fantastic option for your car’s power steering fluid provided your BMW owner’s handbook says that you can use that with your model. If not, check to see what the manufacturer has to say about ATF.
- Power steering fluid made by Prestone with a stop leak. Although not specifically designed for BMW, this is useful for models that were produced before 2012 since it’s a great additive for vehicles that once used ZF hydraulic power steering racks, which BMWs had.
- J1B1001 Power Steering Fluid by Ravenol. Another good aftermarket alternative for your BMW is ravenol. It aids in the prevention of corrosion and fosters thermal stability and was specifically designed with luxury vehicles like BMW in mind.
- European Power Steering Fluid from Prestone. This synthetic fluid was created especially for BMW and other European vehicles. It’s a wonderful alternative for topping off your power steering fluid to keep your BMW running at peak performance with no noise or wear and tear, even though it’s a bit pricy for the very small quantity you receive. Having said that, alternative steering fluids offer greater value for the money.
We must make it clear that, if at all feasible, you must choose the Pentosin power steering fluid that corresponds to the model year shown as the first option in the above list. The Pentosin is what the manufacturer recommends universally, while the other possibilities may work well for your model if your owner’s manual specifies that other types may be used in it.
