Is there a way to adjust the heavy steering wheel of a BMW?

There is no way to adjust the heavy steering wheel of a BMW. Below is the relevant introduction about the steering wheel: Structural characteristics: The structure of the electro-hydraulic power steering system mainly includes a power steering gear, steering force sensor, one-way valve, speed sensor, steering control light, speed sensor, engine sensor, oil reservoir, pressure limiting valve, electro-hydraulic pump, and power steering gear ECU. Working principle: The principle of electro-hydraulic power assistance is basically the same as that of mechanical hydraulic power assistance, the difference being that the oil pump is driven by an electric motor, and the assistance force is variable. The speed sensor monitors the vehicle speed, and after obtaining the data, the electronic control unit adjusts the opening degree of the steering control valve to change the oil pressure, thereby achieving the adjustment of the steering assistance force.
When I used to drive a BMW, I encountered an issue where the steering wheel was too heavy, making it feel like there was excessive steering resistance, which even made my arms sore. This is usually a problem with the electric power steering system, such as inaccurate sensor signals or a faulty power assist module. You can first check the tire pressure yourself—if it's too low, it can increase steering difficulty. If the pressure is normal, you should visit a BMW dealership to use a diagnostic tool to check for error codes. They might recalibrate the power assist settings or replace components. A heavy steering wheel affects handling and can lead to loss of control during turns, so safety shouldn't be overlooked. I've dealt with this myself, and after professional adjustments, the steering became much lighter. Don't skimp on this small expense, as it could also be a precursor to other issues, such as loose chassis components or axle problems. Regular maintenance can prevent these issues—don't wait until something goes wrong to regret it.
