Xenon Headlight Ballast Compatible With Audi 8K0941597E D3S And D4S

If your vehicle’s xenon headlights flicker, delay ignition, or fail completely, this aftermarket ballast restores reliable high-intensity discharge illumination. Designed as a direct drop-in replacement for OEM reference numbers 8K0941597E, 8K0941597C, and 2048703226, it supports D3S and D4S xenon lamps across numerous Audi, Volkswagen, and shared platform models. Factory-tested and built to regulate precise voltage levels, this unit stabilizes power delivery to protect expensive HID bulbs from early failure while maintaining crisp, white-light output in low-visibility conditions.

Benefits & Practical Tips

A functioning ballast extends the lifespan of your xenon bulbs by preventing electrical spikes and inconsistent current flow. To ensure a seamless swap, always verify your original housing part number before ordering, as production years and regional spec differences affect pin layouts. We recommend having a qualified technician handle the physical installation since no wiring diagrams are included in the box.

Important Reminders

This is high-performance aftermarket hardware engineered to match factory dimensions and electrical output. Because professional installation is strongly advised, please inspect your existing fuse ratings and connector terminals before removing the old unit, as degraded grounding points or blown fusible links frequently mimic ballast defects. Please allow one to two millimeters of physical variance during bracket alignment due to standard production tolerances.
