What this part does
The power steering line transports hydraulic fluid between the power steering pump, the steering rack, and the fluid reservoir. Depending on its position in the system, it either carries high-pressure fluid to assist with steering effort or routes low-pressure fluid back to the reservoir. When a steering line fails or its crimps degrade, it causes hydraulic leaks that lead to a heavy steering feel, whining noises from the pump, and eventual damage to the steering rack.

Before you order
Verify exactly which line you are replacing, as the E39 steering system uses distinct high-pressure, return, and cooling loop lines with different fittings. Check the cap on your power steering fluid reservoir to confirm whether your specific chassis requires ATF or Pentosin CHF 11S fluid, as BMW used both during this production era and mixing them will destroy the seals in the rack. Always use new crush washers on any banjo bolt connections during installation to prevent air ingress and fluid leaks.
