Product Details

Part number ER9110 is remanufactured from inspected cores that are disassembled, cleaned, shot-peened, and rebuilt with wear components replaced to restore original steering operation and finish. For belt-driven racks, the belt is replaced, harmonically balanced, and tensioned to OE specifications. The unit is then cleared of internal faults, cycled repeatedly, and tested in a vehicle-simulation process to confirm proper function before packaging.

Use ER9110 when replacing a worn or failed electric power steering rack on Audi A4, Audi A5 Quattro, Audi S4, and Audi RS5 vehicles equipped with PR code QZ7. This part cross-references Audi OE numbers such as 8K1423055AC and 8K1423055AJ for the same application.

Common Problems This Part Can Address

• Excessive steering play or loose steering response
• Electric power steering warning lights or fault codes
• Uneven or inconsistent steering assist
• Noise, binding, or rough steering operation
• Failure of the original rack and pinion assembly

Installation Notes

Before installation, confirm PR code QZ7 and verify vehicle application by year, make, and model. Programming is required using a SAE J2534 Pass-Thru device with OEM software, and steering angle plus torque sensor calibration must be completed after installation. Proper alignment and system initialization should be performed once the rack is installed.
