Audi 80 90 ZF Power Steering Pump

The 050145155AX power steering pump supplies hydraulic pressure to the vehicle’s power steering system, helping reduce steering effort and providing assisted steering during low-speed maneuvering and normal driving.

A failing power steering pump can produce symptoms such as:

• Heavy or difficult steering
• Whining or abnormal pump noise
• Reduced steering assistance
• Hydraulic fluid leakage
• Inconsistent power steering operation

Replacing a worn pump with the correct OE/ZF specification can help restore the intended operation of the hydraulic steering system.

Vehicle Fitment

Potential applications may include compatible:

• Audi 80 B3
• Audi 80 B4
• Audi 90 B3
• Audi Coupe B3/B4
• 2.0L 4-cylinder petrol models
• Potential engine codes: ABT, ABK, 3A, 6A, AAD
• Approximately 1987–1995

Exact compatibility depends on the vehicle’s model year, engine code, drivetrain, steering configuration, pump mounting arrangement, pulley configuration, and hydraulic connections.

Important Fitment Information

Please verify the following before ordering:

• OEM part number: 050145155AX
• ZF pump identification
• Engine code
• Vehicle model and year
• Pulley configuration
• Mounting points
• Hydraulic hose connections
• Original power steering pump

Engine-code and part-number matching is strongly recommended. Not every Audi 80, 90, or Coupe uses the same power steering pump.

Condition

This is a genuine used ZF/OEM power steering pump.

As a pre-owned mechanical component, it may show normal signs of previous use, including cosmetic marks, surface wear, or age-related discoloration.

Please inspect the available photographs carefully and compare the pump’s physical configuration, pulley, mounting points, and connections with your original unit.

Because this is a used hydraulic component, professional inspection before installation is recommended.

Installation & Safety

Professional installation is recommended.

Before installation, inspect the power steering hoses, reservoir, belt, pulley, mounting hardware, and related steering components. Flush or replace contaminated hydraulic fluid as appropriate for the vehicle and steering-system specification.

After installation:

• Check all hydraulic connections.
• Fill with the correct steering fluid.
• Bleed the power steering system according to the vehicle manufacturer’s procedure.
• Check for leaks.
• Verify smooth steering assistance.
• Inspect the pump for abnormal noise.
• Confirm correct belt and pulley operation.

The steering system is safety-critical, so the vehicle should be properly inspected after installation.
