Although electric power steering is increasingly common, many popular late-model European vehicles, such as the 2007 BMW 328i, still use hydraulic power steering systems.

When doing any repair or service that involves changing the hydraulic fluid on one of these cars, it’s a great idea to change the power steering fluid reservoir at the same time.

Here’s why: On many models, the power steering fluid reservoir has a filter built into the reservoir. The filter itself is not serviceable…if you need a new filter, you need a new reservoir.

Starting with a new filter whenever you change the power steering fluid is a great idea — you avoid the risk of having contaminants from a used filter getting into your new power steering fluid.

Because it’s recommended to change the reservoir at the same time as the fluid, CRP Automotive offers a kit that contains the approved power steering fluid and a Rein Automotive OE-quality power steering reservoir.

Here are the applications CRP Automotive offers this kit for: BMW 128i, 135i, 135is, 323i, 325i, 325xi, 328i, 328xi, 330i, 330xi, 335d, 335i, 335xi, M3, X1, X3
