Detailed Description

BBB Industries N990-1001 is a new power steering pump engineered for Audi models that use a remote reservoir, non-reservoir style steering setup. The aluminum housing supports a service replacement build, while the threaded outlet and pipe-style inlet help match the original connection points on the vehicle. This part number, N990-1001, is listed for 2002-2009 Audi A4, 2002-2009 Audi A4 Quattro, and 2002 Audi S4 applications.

This pump is a practical choice when replacing a worn or noisy steering pump on an Audi A4, Audi A4 Quattro, or Audi S4 with the correct non-reservoir configuration. This part cross-references 19319580 for the same application.

What It Can Help Address

• Hard or inconsistent steering effort
• Whining or groaning from the power steering system
• Fluid leakage at the pump connections
• Poor hydraulic pressure delivery to the steering gear
• Failure of the original pump on non-reservoir Audi steering systems

Installation Notes and Tips

Verify the vehicle uses a non-reservoir style power steering pump before installation. Confirm inlet and outlet thread sizes, pulley style, and mounting-hole layout against the original unit. Inspect the serpentine belt, hoses, and fluid condition during replacement to help avoid repeat steering system issues. Proper bleeding of the power steering system after installation is important for quiet operation and consistent assist.
