Magneti Marelli AC484 Front Window Winder

Magneti Marelli AC484 Front Window Winder

The Magneti Marelli AC484 is a high‑performance front window winder, also known as an electric window regulator, designed to replace the original component in a wide range of Volkswagen and Audi vehicles. This unit delivers smooth, quiet operation while maintaining the durability expected from a genuine OEM part.

Key Features & Technical Highlights

• Precision Engineering: Crafted with high‑strength steel gears and reinforced plastic housings to withstand continuous use without wear or failure.
• Quiet Operation: Integrated noise‑dampening technology reduces motor whine, ensuring a silent ride even at full speed.
• Compact Design: The AC484’s slim profile fits seamlessly into the existing door architecture without requiring extensive modifications.
• Robust Motor: Equipped with a low‑voltage DC motor that delivers consistent torque, allowing smooth opening and closing of the window at all temperatures.
• Seamless Integration: Designed to match the original wiring harness and control module, enabling plug‑and‑play installation for technicians.

Compatibility Overview

The AC484 is engineered for front right door windows in a variety of Volkswagen models, including but not limited to:

• Volkswagen Golf IV (1J1)
• Volkswagen Bora (4 V)
• Volkswagen Variant
• Audi models sharing the same door architecture

Its counterpart, the left‑hand side unit, shares identical specifications and can be swapped if necessary. The part number 350103484000 is universally recognized across all supported platforms.

Installation Guide

1. Disconnect Power: Remove the vehicle’s battery or disconnect the door control module to prevent accidental activation during installation.
2. Remove Existing Regulator: Unscrew the mounting bolts, detach the wiring harness, and carefully lift the old regulator out of the door panel.
3. Prepare AC484: Align the new unit with the mounting holes. If necessary, use the supplied spacer to match the original clearance.
4. Secure Mounting: Tighten all bolts to the manufacturer’s torque specifications (typically 10–12 Nm). Ensure no play in the regulator assembly.
5. Reconnect Wiring: Plug the harness into the new unit, verifying correct polarity and connector orientation.
6. Test Operation: Reconnect power and operate the window switch. The AC484 should lift or lower the glass smoothly within a few seconds.

Operation & Performance

The AC484’s motor is calibrated to provide optimal torque across the entire travel range of the window. When the driver presses the window button, the unit engages the gear train, translating electrical energy into mechanical motion that raises or lowers the glass panel. The regulator’s design ensures:

• Consistent Speed: Uniform movement regardless of load or temperature.
• Safe Stop Mechanisms: Built‑in limit switches prevent over‑travel, protecting both the window and the door frame.
• Low Maintenance: With no exposed moving parts beyond the gear train, routine checks are minimal.

Maintenance Tips

• Inspect the regulator housing for cracks or deformation every 12 months. Replace immediately if any damage is found.
• Check the wiring harness for corrosion or fraying. Clean contacts with a soft brush and apply dielectric grease to connectors.
• Lubricate the gear teeth with a light machine oil once per year to reduce wear and noise.
• Verify that the window stops at the correct positions by testing both fully open and fully closed states.
