Quick Answer
Audi A6 C7 headlight assemblies (2011โ2018) used Xenon/Bi-Xenon headlights early on, with full LED and Matrix LED added from the 2014 facelift. Pre-facelift (2011โ2014) and facelift (2015โ2018) units differ. Quality 1:1 aftermarket assemblies match OEM fitment and beam pattern at a fraction of genuine-Audi pricing โ confirm your build date and original type, and note that converting Xenon to LED/Matrix usually needs different assemblies, possibly a harness, and coding.
Introduction
The A6 C7 is a frequent candidate for headlight repair or upgrade, often due to condensation, Matrix LED segment failures, or a desire to move from xenon to the LED look. This guide explains the variants and how to buy correctly.

Understanding the Audi A6 C7 Headlight Variants
1. Xenon / Bi-Xenon (2011โ2014)
Standard on pre-facelift cars. Xenon projector with ballast and, on adaptive versions, cornering and auto-leveling. Ballast and module faults are common with age.
2. Full LED (facelift, 2015โ2018)
Full-LED headlight with a sharper signature, introduced with the 2014 facelift.
3. Matrix LED (facelift, premium)
Adaptive system with individually controlled LED segments for glare-free high beam. Individual segment or control-module failures are a known issue, and replacement usually requires bumper removal and electronic calibration.
The 2014 facelift cutoff matters โ order to your production date, not just the model year.
OEM vs Aftermarket: What to Know
OEM-grade aftermarket units replicate factory optics, connectors and beam cut-off for plug-and-play fitment. Low-quality units risk condensation, dipped-light errors and segment failures. A verified factory source plus coding for conversions avoids these.
Fitment Checklist: Confirm Before Ordering
- Production date โ Pre-facelift (2011โ2014) vs facelift (2015โ2018).
- Original headlight type โ Xenon/Bi-Xenon, full LED, or Matrix LED.
- Body style โ A6 sedan, A6 Avant (and S6/RS6 where applicable).
- Traffic side โ LHD vs RHD.
- Coding readiness โ Xenon-to-LED/Matrix conversions need different assemblies and coding.
Installation Notes for Workshops
- Remove the front bumper to access the headlights.
- Release the connector lock before unplugging.
- For conversions, fit the correct assemblies/harness and code the car so the lights are recognised and warnings clear.
- Calibrate adaptive headlights and finish with an aim check.
Total Cost Comparison
| Factor | OEM-Grade Aftermarket | Genuine Audi |

| Fitment | Plug-and-play (date-matched) | Plug-and-play |
| Coding | Needed for conversions | Not needed (like-for-like) |
| Lead time | In stock, fast DDP | Often back-ordered |

Frequently Asked Questions
Why is my Matrix LED headlight showing a fault or steam?
Common causes are a failed LED segment/control module or condensation from a seal issue. A quality replacement with correct coding and calibration resolves it.
Can I convert my xenon A6 to full LED?
Yes, but a proper conversion needs LED/Matrix assemblies (and sometimes a harness) plus coding โ it is not a simple bulb swap.
Pre-facelift or facelift?
Check the production date (2014 is the cutoff); facelift cars have the LED/Matrix signature.
