MOTOKU Xenon Headlight Ballast Control Unit with Igniter and D3S Bulb — OE Fit for Audi/Volkswagen/Porsche (Complete HID Assembly)

The MOTOKU Xenon Headlight Ballast Control Unit with built-in igniter and D3S bulb is a complete replacement kit designed to restore proper HID lighting performance for compatible Audi, Volkswagen, Porsche and select Chrysler/Dodge models.

When a factory HID/bi-xenon headlight fails, the ballast, igniter or bulb can be the culprit. This MOTOKU assembly combines a matched ballast control unit, integrated igniter and a D3S xenon bulb so you can replace the entire lighting module with one part. It’s engineered to match OE fitment and electrical behavior for a long list of late-model European and a few American vehicles, helping eliminate flicker, no-starting or lamp-out faults without complex diagnostics.

Which vehicles will this MOTOKU ballast fit?

This unit was manufactured for a wide range of Audi and Volkswagen platforms plus selected Porsche, Chrysler and Dodge vehicles from roughly 2008–2018. Fitment targets cars originally equipped with D3S xenon systems; confirm your VIN or existing part number before ordering.

• Audi: many A3/A4/A5/A6/A7/A8/Q5/Q7/S models across 2008–2017 model years.
• Volkswagen: CC, Jetta, Eos, Tiguan, Touareg, Polo, Passat, GTI and Golf variants (2011–2018 ranges).
• Also compatible with Porsche Macan (2015–2017), Chrysler 300 series (2011–2017) and Dodge Viper (2013–2016).

How does replacing the entire ballast, igniter and D3S bulb help?

Swapping the full assembly reduces troubleshooting time by addressing all common failure points at once—power conversion, ignition pulse and the bulb itself. That lowers the chance of repeat failures caused by mixing old and new components.

• Eliminates compatibility mismatches between old ballast and new bulb.
• Reduces diagnostic steps—install and test rather than isolate faults.
• Restore stable output to prevent flicker, delayed startup, or warning lights.

What should I check before buying to ensure correct fit?

Verify that your vehicle uses D3S xenon bulbs and compare the existing part number or connector style to the MOTOKU unit. Measure mounting points and confirm year/model coverage against your VIN to prevent ordering the wrong ballast variant.

• Confirm bulb type: D3S xenon lamp required.
• Match the electrical connector and mounting tabs to your housing.
• Use your VIN or OEM part number to cross-check vehicle compatibility lists.

Will installing this MOTOKU unit be difficult for a DIYer?

Installation difficulty varies by vehicle; many front-end assemblies require removing the headlight housing or accessing the engine bay through fender liners. A mechanically inclined DIYer can perform the swap with basic tools, but professional installation avoids alignment and sealing issues.

• Expect moderate skill: remove headlamp, unplug old unit, bolt in new ballast.
• Handle the D3S bulb without touching the glass to avoid premature failure.
• After installation, check for error messages and verify beam alignment.

Who is this for: The MOTOKU Xenon Ballast Control Unit kit suits owners of late-model Audi and Volkswagen vehicles (and select Porsche, Chrysler, Dodge models) originally equipped with D3S xenon lighting who want a single, matched replacement for ballast, igniter and bulb. It’s aimed at technicians, independent shops and confident DIYers who prefer replacing the complete HID module to minimize repeat visits and restore reliable, factory-like headlight performance.
