When to Change Power Steering Fluid

Model: BMW Serie 5 E39 - Years 1995-2003
Part: Power steering fluid

Cars equipped with power steering have a reservoir that contains the fluid needed to lubricate the gears. If the car consumes too much fluid, it can lead to a very noisy steering system. If this fluid runs low, it could even cause the power steering motor to fail. Therefore, it is necessary to check and add more fluid if needed. If the fluid level is at the minimum, adding a whole quart will suffice; if it is halfway, you can add more and save the remainder. With the change of power steering fluid, the difference is noticeable as there will be less noise and a significantly smoother steering feel.
