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

Aynaxcol 8K0941597B is a complete xenon headlight kit—ballast, igniter and D3S bulb—made to replace OEM units on select Audi, VW, Touareg and Chrysler models for a plug-and-play restoration of HID lighting performance.

If your vehicle’s HID lights are flickering, slow to start, or not lighting at all, a faulty ballast or igniter is often the cause. This replacement assembly matches the OEM reference 8K0.941.597 and W003T20171, delivering the voltage and current control needed to start and stabilize D3S xenon bulbs without requiring vehicle coding or programming.

Will this fit my Audi or Volkswagen model?

Yes—this unit was engineered to be compatible with a broad set of Audi and VW models across multiple years. Check the specific model and year against the compatibility list to confirm fit before ordering.

• Fits Audi: A3/A3 Quattro (2009–2011, 2015–2016), A4/A4 Quattro (2009–2016), A5/A5 Quattro (2010–2017)
• A6/A6 Quattro (2009–2015), A7 Quattro (2012–2015), A8 Quattro (2011–2014), allroad (2013–2016)
• Q7 (2010–2015), Q5 (2009–2017), RS5, S4–S8 variants per listed years

What comes in the box and how does it replace the original part?

The package includes the ballast control unit, a matched D3S xenon bulb, and the igniter—everything needed to swap out a failing HID assembly. The ballast supplies the high voltage to start the bulb and then regulates current to maintain stable light output, functioning as the electronic control for the HID lamp.

• 1x Xenon light ballast control unit (reference 8K0.941.597 / W003T20171)
• 1x D3S xenon bulb matched to the ballast
• 1x Igniter to ensure proper start-up of the D3S bulb
• Designed to replace OEM ballast without additional coding

How difficult is installation and do I need special tools or coding?

Installation is straightforward for anyone familiar with headlight access and bulb replacement. The Aynaxcol ballast is built for plug-and-play connection to original harnesses, so no programming or vehicle coding is required—only basic hand tools for reaching the headlamp assembly.

• Direct fit with OEM connectors—no soldering or splicing
• Typical install requires removal of headlamp housing or access panel
• Recommended: gloves for bulb handling and a torque-limited driver for fasteners

What performance and safety considerations should I expect?

This replacement restores proper ignition and stable xenon light output when the original ballast has degraded. While the product supplies voltage conversion and current control, ensure correct bulb type (D3S) and secure mounting to avoid vibration-related failures.

• Restores quick start-up and prevents flicker caused by failing ballast
• Converts vehicle DC to the AC characteristics the xenon bulb requires
• Use matched D3S bulb provided; handle glass with gloves to prevent oil contamination

Who is this for: This Aynaxcol 8K0941597B assembly is designed for DIY mechanics, independent repair shops, and vehicle owners who need a reliable, OEM-referenced replacement for failing HID electronics on supported Audi, VW, Touareg, Jetta and Chrysler 300 models. It suits anyone who wants a complete, plug-and-play ballast solution that includes the proper igniter and D3S bulb to restore HID performance without dealer reprogramming.
