why does my Volkswagen Golf make a hissing noise when I turn the steering wheel

Solution

1. Preparation

• Ensure the vehicle is parked on a level surface.
• Disconnect the negative battery terminal to prevent electrical shorts.
• Gather tools including a socket set, fluid catch pan, and power steering fluid.

2. Inspect the Power Steering Fluid

• Remove the power steering reservoir cap and check the fluid level.
• If low, top off with the manufacturer-recommended power steering fluid.
• If fluid is discolored or contaminated, it may need to be flushed.

3. Check for Leaks

• Use a flashlight to inspect power steering hoses for cracks or loose fittings.
• If any leaks are found, replace the damaged hoses or tighten connections as needed.

4. Inspect the Power Steering Pump

• Remove the pump belt (if applicable) by loosening the tensioner.
• Inspect the pump for any signs of wear or leaks.
• If the pump is faulty, remove it by unscrewing the mounting bolts and disconnecting the hoses.

5. Replace Faulty Components

• If the power steering pump is defective, install a new pump by reversing the removal steps.
• Ensure all hoses are securely connected and there are no leaks.
• Refill the power steering fluid reservoir to the correct level.

6. Test the System

• Reconnect the negative battery terminal.
• Start the engine and turn the steering wheel side to side to circulate the fluid.
• Check for any noises or leaks during operation.
