Detailed Description

This Cardone Power Steering Pump, part number 21-580, is a remanufactured replacement for the Audi Q5 power steering system. It uses an aluminum housing, a press-on pulley attachment, an O-ring hose port type, and a bolt-on outlet connection with one outlet. The unit is supplied with a calibrated pressure relief valve and is hydraulically tested to verify dependable operation before it leaves the remanufacturing process. Cardone’s remanufacturing approach also reduces raw material and energy use compared with producing a new part.

Compatible With 2011-2012 Audi Q5, N/A. This part cross-references Audi OE numbers 8R0145153C and 8R0145153D for the same application. Cardone 21-580 is a direct-fit service part for Audi Q5 steering repair where the original pump has lost pressure, become noisy, or developed leakage.

What It Helps Fix

• Hard steering or reduced steering assist
• Whining or pump noise during operation
• Fluid leaks from worn seals or O-rings
• Inconsistent pressure or bypass performance
• Steering effort changes caused by internal wear or contamination

Installation Notes and Tips

Fits 2011-2012 Audi Q5, N/A. Reservoir not included. An in-line filter, OE fluid, and a full system flush are required for warranty on the listed Audi Q5 applications. Before installation, inspect the pulley fit, flush the steering system, and bleed air from the circuit after assembly. If the original pump failure was caused by contamination, clean the flow control valve and related passages before putting the vehicle back into service.

Quality Assurance

Cardone remanufactures this pump to OE-level standards and tests critical hydraulic functions before release. The final assembly is checked for pressure, flow, bypass, valve operation, steering effort, and noise to help confirm reliable performance on Audi Q5 service applications.
