Audi Q7 4M Facelift Headlight Compatibility Guide

Last updated: July 30, 2026

Fast answer: For an Audi Q7 4M facelift headlight conversion, verify vehicle phase, LED technology, market, modules, connector pinout, component-protection implications and calibration requirements.

This guide is a pre-purchase verification framework for workshops, importers and owners. It does not replace VIN-level EPC, wiring-diagram or local compliance checks.

Product Association

Use this guide together with the Audi Q7 4M headlight products search and ask the supplier to identify the exact revision, included modules and market specification in writing.

OEM Reference

Use the VIN PR-code list and the complete lamp label. Check left/right numbers, revision letters and all attached module numbers; housings with the same outer appearance may use different electronics.

• Record the full VIN and production month.
• Photograph the original lamp label, connector face and installed control modules.
• Compare supersession history and left/right-hand-traffic specification.

Installation Evidence

Before ordering, request an optical-function video, diagnostic scan, module-identification report, connector photographs and a beam-alignment result from the same specification. Evidence should show the same vehicle phase and option level—not merely a similar body shape.

Installation Notes

1. Save a full vehicle scan and module coding backup.
2. Trial-fit the lamp with adjacent bumper, grille and fender interfaces loose.
3. Resolve component-protection and parameterization requirements through an authorized workflow where applicable.
4. Calibrate leveling/advanced-lighting functions and align the beam.

Compatibility Warning

Matrix functions and traffic-side behavior depend on hardware, software, camera data and local regulation. A lamp that illuminates is not necessarily a fully compatible or compliant installation.

Workshop Tips

• Check repair tabs and housing ventilation before installation.
• Use a supported battery maintainer during programming.
• Retain scan reports from before and after the retrofit.

Decision Checklist

• VIN and production date verified
• Original lamp technology documented
• Connector, module and harness plan confirmed
• Coding/calibration scope quoted
• Return terms tied to the verified specification

FAQ

Are all Q7 4M facelift headlights interchangeable?

No. LED technology, market, revision, modules and vehicle PR codes can differ.

What is component protection?

Certain control modules may require an authorized adaptation process before operating correctly in another vehicle.

Is beam alignment enough after installation?

No. Some configurations also require coding, parameterization, fault checks and sensor or camera calibration.
