Aynaxcol Xenon Headlight Ballast Kit with Igniter & D3S Bulb — 8K0941597B Plug-and-Play for Audi, VW, Touareg

Aynaxcol 8K0941597B is a complete xenon headlight replacement kit—ballast, igniter, and D3S bulb—designed to drop in for many Audi, Volkswagen, Touareg and Chrysler models.

If a factory xenon lamp fails, the ballast and igniter are often the root cause; this Aynaxcol kit supplies the correct voltage regulation and ignition components plus a D3S bulb so you can restore HID performance without coding or complex installation. The unit matches OE form and fit for many model years and includes all three components needed to replace a failed system quickly.

Which vehicles will this Aynaxcol xenon ballast fit?

This kit is built to replace factory ballast units on a wide range of Audi, VW, Touareg and select Chrysler models. Compatibility covers many popular A and S series Audis, Q5/Q7 SUVs, CC, Eos, Jetta and Touareg ranges across the model years listed by the manufacturer.

• Audi: A3/A4/A5/A6/A7/A8, Q5/Q7, S4/S5/S6/S7/S8 and RS5 across specified years.
• VW: CC (2013–2014), Eos (2012–2014), Jetta (2013–2014).
• Touareg 2011–2014 and Chrysler 300 2011–2017 compatibility noted.

How does the Aynaxcol ballast restore HID lamp function?

The ballast supplies the initial high-voltage pulse needed to ignite the xenon arc and then regulates the current to maintain a stable light output. It can also perform DC-to-AC conversion where required, allowing the vehicle’s DC electrical system to drive the HID bulb correctly.

• Provides ignition pulse for D3S bulb start-up.
• Regulates running voltage to prevent flicker and protect the bulb.
• Acts as a DC-to-AC converter when required by the headlamp system.

Will I need to program or code this ballast after installation?

No special coding or programming is required for most compatible vehicles; the Aynaxcol unit is designed as a plug-and-play replacement using the listed OE part references. That said, always verify fit and connector type against your damaged unit before purchase to avoid wiring mismatches.

• Manufacturer reference numbers: 8K0.941.597 and W003T20171.
• Plug-and-play design—no ECU coding for the majority of listed models.
• Confirm connector and mounting points with existing unit prior to installation.

What comes in the package and what should I expect during swap-out?

The kit ships with one xenon ballast control unit, one D3S bulb, and one igniter so you have all primary components for a full lamp replacement. Installation typically involves removing the headlamp access cover, unplugging the old ballast and igniter, swapping in the new components, and testing illumination before reassembly.

• Package includes: 1x ballast, 1x igniter, 1x D3S xenon bulb.
• Expect basic hand tools and headlamp access; some models may require bumper or inner fender removal.
• Test lights before sealing the headlamp housing to ensure proper operation.

Who is this for: The Aynaxcol 8K0941597B kit is aimed at DIY mechanics, independent repair shops, and owners of compatible Audi, VW, Touareg or Chrysler vehicles who need a reliable, OE-referenced ballast replacement without dealer programming. Choose this kit when you want a full, plug-and-play replacement—ballast, igniter and bulb—in one package to restore HID lighting quickly and efficiently.
