HID D2S Xenon Ballast for Audi 4E0907476 A0028202326 Control Module
Restore consistent daylight illumination in vehicles equipped with xenon headlights using the Malcayang D2S HID ballast. Engineered as a direct aftermarket replacement for control module 4E0907476, this component supplies stable ignition voltage to the projector lamp, resolving flickering, slow cold-starts, and unpredictable burnout cycles that typically plague aging automotive lighting circuits.
Benefits & Practical Tips
- Match your chassis generation and existing OEM numbers precisely to guarantee correct wiring pinouts and voltage regulation.
- Always disconnect the vehicle battery before wiring to protect sensitive CAN-bus architectures from electrical spikes.
- Install alongside a new D2S xenon bulb to maximize beam pattern accuracy and prevent rapid color shift in the optic projection system.

Installation & Safety Notes
This unit functions as an aftermarket replacement component. Comprehensive wiring diagrams or installation manuals are not supplied with the shipment. Because xenon systems require high initial voltage and integrate directly into factory lighting harnesses, hiring a qualified technician is strongly recommended. Manufacturing tolerances may result in a physical variance of 1–2 mm, and screen calibration differences can cause slight color deviations compared to product photographs.
