How to Check the Power Steering Fluid on a 2002 BMW 325

1. Open the car’s hood. The power-steering reservoir on a 2002 325i is located next to the coolant reservoir in the engine bay above the power-steering pump.
2. Clean the power-steering fluid reservoir and the area around it with a clean rag to avoid any dirt and debris getting in the fluid. Turn the lid of the reservoir by hand counterclockwise to loosen and remove it.
3. Look at the bottom of the lid, which will have a plastic dipstick on it. Wipe the dipstick with a rag so that it is clean and then dip it back in the reservoir. Pull it back out and look at the dipstick.
4. Pour the appropriate amount of fluid into the reservoir until the dipstick shows that it is to the full mark. Replace the lid for the reservoir. If the fluid level was very low, turn the steering wheel back and forth through the full range to make sure the steering is not heavy and does make any strange noises.
