The Volkswagen Polo 1.6 steering motor is part of the Electric Power Steering (EPS) system, which replaces the traditional hydraulic pump with an electric motor for smoother, more efficient steering control.

Description:

• Type: EPS (Electric Power Steering) motor with control unit integrated.
• Function: Provides power assistance to the steering column by electronically adjusting torque based on driving conditions and steering input.
• Placement: Mounted on the steering column or rack, depending on model year/variant.
• Operation: Receives signals from sensors (steering angle sensor, torque sensor, vehicle speed sensor) and the ECU, then applies the necessary assistance.
• Features:
  
• Energy efficient compared to hydraulic systems (only works when steering input is needed).
• Integrated ECU (in many models) for controlling steering assist and safety functions.
• Provides variable steering effort lighter at low speeds (parking), firmer at high speeds (highway).
• Built-in diagnostics for faults (often triggers EPS warning light if malfunctioning).
• 
  

Common Issues:

• Motor wear or failure (loss of power assist).
• Control unit malfunction (EPS warning light on).
• Torque/angle sensor faults (erratic steering feel).

Would you like me to make the description more like a used parts listing style (short, direct, and sales-friendly), like the other car parts descriptions you’ve been asking?
