What are the reasons for the heavy steering in Volkswagen vehicles?
3 Answers
Volkswagen steering feels heavy due to: failure of the power steering pump; misalignment of tire positioning or insufficient tire pressure, etc. Categories of power steering systems: The power steering systems equipped in vehicles can generally be divided into three categories: mechanical hydraulic power steering systems, electro-hydraulic power steering systems, and electric power steering systems. The mechanical hydraulic power steering system typically consists of components such as a hydraulic pump, oil pipes, pressure and flow control valve body, V-type drive belt, and oil reservoir. Function of the power steering system: Power steering assists the driver in adjusting the vehicle's direction, reducing the effort required to turn the steering wheel. Additionally, power steering plays a certain role in the safety and fuel efficiency of the vehicle during operation.
I've driven Volkswagen cars for over a decade and repaired many friends' vehicles. There are quite a few reasons for heavy steering. The most common issue is problems with the power steering system, such as a faulty electric power steering module or broken sensors, which result in insufficient assistance to the steering wheel. Another reason is low tire pressure, making the wheels harder to turn and consequently the steering heavier. Sometimes, missing or dirty steering fluid in a hydraulic power steering system can cause this—my old Golf once had a fluid leak that made the steering extremely heavy. Additionally, misaligned wheels or suspension system issues can also make the steering wheel harder to push or pull. Safety-wise, heavy steering can lead to fatigue and potential loss of control, especially at high speeds. It's best not to delay and get it checked at a professional shop—test the battery and power steering system. Regular maintenance can help prevent such issues.
As an ordinary person who drives frequently, I once experienced a sudden heavy steering wheel in my Volkswagen Tiguan, which gave me quite a scare. Later, the mechanic explained that insufficient battery power affected the normal power supply to the power steering system, and replacing the battery solved the issue. Other reasons like wear and tear of steering column components or foreign objects getting stuck can also make the steering feel heavier. That time, my friend's car had heavy steering due to mud stuck on the wheel rims in the snow. It's important to remind everyone not to force the steering when it feels heavy, as it can easily strain the wrists or back. Before hitting the highway, it's best to self-check tire pressure and lights, and send the car for repair immediately if any issues are found. For cars like Volkswagen, maintaining a stable electrical system is crucial to avoid unnecessary expenses on major repairs.
