Goodpart TYC LWR 20-11813-MA-1 Servomotor

The Goodpart TYC LWR 20-11813-MA-1 Servomotor is a precision-engineered actuator designed to provide reliable, smooth, and accurate control of headlight leveling systems in a wide range of passenger vehicles. Its compact form factor, robust construction, and advanced electronic interface make it an ideal replacement or upgrade for OEM units across multiple automotive brands.

Key Functional Characteristics

• High-Precision Positioning: The motor delivers micro‑step resolution, enabling fine adjustments of headlight elevation to within a few millimeters. This precision ensures optimal beam alignment for both daytime running lights and high‑beam illumination.
• Integrated Feedback Loop: Equipped with an internal encoder or potentiometer, the servomotor continuously reports its position back to the vehicle’s control unit. This closed‑loop system guarantees repeatable performance even under varying temperature and load conditions.
• Low Power Consumption: Operating at a nominal voltage of 12 V DC, the motor consumes minimal current during idle periods while still delivering sufficient torque for rapid headlight adjustment when commanded.
• Durable Mechanical Design: The gear train is constructed from high‑strength alloy steel with hardened teeth, providing long service life and resistance to wear. Sealed bearings protect against dust and moisture ingress.
• Compact Dimensions: With a length of approximately 70 mm and a width of 35 mm, the unit fits easily into tight engine bay spaces without requiring extensive modifications.

Electrical Interface and Compatibility

The servomotor communicates via a standard CAN‑bus or LIN‑bus protocol, depending on the vehicle’s architecture. It accepts command signals in the form of pulse width modulation (PWM) or digital position commands, allowing seamless integration with existing headlight control modules.

Voltage Range: 12 V DC ±10% Current Rating: 1.5 A peak Signal Type: PWM (0–100 µs) or digital position code

Installation Overview

1. Remove the OEM Servomotor: Disconnect the electrical harness, unscrew mounting bolts, and carefully detach the unit from the headlight assembly.
2. Mount the Goodpart TYC LWR 20-11813-MA-1: Align the mounting flange with the pre‑drilled holes in the vehicle chassis. Secure using supplied screws and torque specifications.
3. Connect the Electrical Harness: Match the pins to the corresponding connectors on the new motor, ensuring correct polarity and signal integrity.
4. Verify Alignment: Use a laser level or headlight alignment tool to confirm that the motor’s output shaft is correctly positioned relative to the headlamp housing.
5. Test Functionality: Power on the vehicle, activate the headlight leveling routine via the dashboard controls, and observe smooth movement of the headlights. Adjust calibration parameters if necessary through the vehicle’s diagnostic interface.

Supported Vehicle Platforms

The motor is designed to fit a broad spectrum of models, including but not limited to:

• Audi A3, A6, and other 8P1/8PA variants (2003‑2007)
• Mercedes‑Benz C‑Class, E‑Class, and Sprinter vans
• Volkswagen Golf, Passat, Polo, Jetta, and Beetle series
• Opel Insignia, Astra, and other compact cars
• Various light‑weight SUVs and crossovers that employ headlight leveling systems

Performance Benefits

• Enhanced Safety: Accurate headlight alignment reduces glare for oncoming traffic while maintaining optimal illumination of the road ahead.
• Reduced Maintenance: The motor’s sealed bearings and robust gear train lower the likelihood of mechanical failure, decreasing service intervals.
• Improved Reliability: Closed‑loop control ensures consistent performance across temperature extremes and during prolonged operation.
• Easy Diagnostics: Built‑in status indicators allow technicians to quickly identify faults such as overcurrent or position errors via standard OBD‑II tools.
