Metzger Window Regulator

Metzger Window Regulator 2160257

The Metzger Window Regulator 2160257 is a high‑performance component designed for the electric window system of Volkswagen vehicles, particularly the Polo series. It serves as the core mechanism that translates electrical input into smooth, reliable movement of the vehicle’s side windows.

Key Functional Features

• Precision Engineering: Crafted with tight tolerances to ensure consistent window lift and lowering across all operating cycles.
• Durable Construction: Made from high‑strength alloy materials that resist corrosion, wear, and fatigue over extended use.
• Compact Design: Fits seamlessly into the limited space of the front right door assembly without compromising other components.
• Low Noise Operation: Equipped with advanced bushings and alignment guides to minimize operational noise and vibration.
• Compatibility: Specifically engineered for Volkswagen Polo models from 2009 to 2014, including variants such as CNKA, CAYA, CLNA, and others.

Installation Overview

The regulator is mounted on the door’s interior panel. Installation requires removal of the existing window assembly, careful alignment of the regulator shaft with the window glass, and secure fastening to the door frame. Proper torque specifications must be observed to maintain structural integrity.

Step‑by‑Step Guide

1. Disconnect the vehicle’s battery to prevent accidental activation.
2. Remove the door panel and existing regulator assembly.
3. Align the new regulator shaft with the window glass track.
4. Screw the regulator into place, ensuring even pressure on all mounting points.
5. Reconnect the electrical connector to the vehicle’s power supply.
6. Test the window operation for smooth lift and lower cycles.

Electrical Integration

The regulator interfaces with the car’s electronic control unit (ECU) through a standard 12‑volt input. It includes an internal motor drive that receives signals from the door switch, translating them into mechanical motion via a gear train.

• Voltage Range: 12 V DC
• Current Draw: Approximately 2–3 A during operation
• Connector Type: Standard automotive plug compatible with Volkswagen wiring harnesses

Maintenance Tips

• Regularly inspect the regulator’s gear teeth for wear or damage.
• Apply a light lubricant to the moving parts during installation to reduce friction.
• Check for any loose screws or mounting bolts and tighten as necessary.
• Avoid exposing the regulator to extreme temperatures or direct sunlight for prolonged periods.

Common Issues & Troubleshooting

• No Window Movement: Verify electrical connections, check fuses, and ensure the regulator is properly seated.
• Squeaking Noise: Inspect bushings for wear; replace if necessary.
• Uneven Lift/Lower: Confirm alignment of the regulator shaft with the window track; adjust as needed.
