my Volkswagen Golf MK7 (2015-2019) power steering is becoming stiff, why is that

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a flat surface and engage the parking brake.
• Disconnect the battery to ensure safety.

2. Fluid Check and Replacement

• Locate the power steering fluid reservoir and remove the cap.
• Check fluid level; if low, top off with the manufacturer's recommended fluid type.
• If the fluid is dirty or has particles, drain the old fluid by disconnecting the return line from the power steering pump.
• Refill the system with new power steering fluid until it reaches the appropriate level.

3. Inspect and Repair Leaks

• Visually inspect all hoses and connections for leaks.
• If leaks are found, replace the damaged hoses or fittings.
• Tighten any loose connections to prevent fluid loss.

4. Power Steering Pump Inspection

• Remove the serpentine belt from the power steering pump.
• Test the pump by turning it manually; it should rotate smoothly without resistance.
• If the pump is faulty, replace it by unbolting it from the mounting bracket and disconnecting the hydraulic lines.

5. Steering Rack Inspection

• Lift the vehicle using a jack and secure it with jack stands.
• Inspect the steering rack for signs of wear or damage.
• If the steering rack is damaged, replace it by disconnecting the tie rods and unbolting the rack from its mounts.
