my BMW 3 Series G20/G21 (2019-2024) power steering feels stiff, is it low on fluid?

Solution

1. Preparation

• Gather tools and parts: OBD-II scanner, fluid catch pan, power steering fluid, funnel, rags, gloves.
• Park the vehicle on a level surface and turn off the engine. Allow it to cool if it has been running.

2. Check and Refill Power Steering Fluid

• Locate the power steering fluid reservoir (refer to the owner's manual for exact location).
• Clean the area around the reservoir cap to prevent dirt from entering.
• Remove the cap and use the dipstick to check fluid level. If low, proceed to the next step.
• Using a funnel, add the appropriate BMW-approved power steering fluid until the correct level is reached.
• Replace the cap securely.

3. Inspect for Leaks

• Visually inspect all hoses connected to the power steering system for signs of leaks.
• Pay attention to the power steering pump and steering rack connections.
• If any leaks are found, replace the affected components.

4. Test Power Steering Pump

• Start the engine and turn the steering wheel left and right.
• Listen for any unusual noises from the power steering pump.
• If the pump is not functioning properly, it may need to be replaced.

5. Reassemble and Clean

• Ensure all caps are replaced securely.
• Clean any spilled fluid to prevent slipping hazards.
• Dispose of any waste fluid properly.
