Because of the design of modern BMW motors, the intake manifold no longer creates enough vacuum to provide the brake system with pressurised assistance. A worn vacuum pump can result in oil leaks, reduced brake performance, or even complete brake failure. This replacement vacuum pump is manufactured by OEM supplier Pierburg, and has been repackaged as a Febi-Bilstein product. Made in Germany.
