How to fix Audi Q7 4L Xenon Headlight? DIY Repair Guide: Ballast, Bulb, Adjuster, AFS Module Change

In this video I am reviewing the bi-xenon headlight of Audi Q7 pre-facelift models (2006-2009). The headlight is adaptive (cornering) type bi-xenon headlight. You can see all replaceable parts at this headlight: Valeo 6G xenon ballast, AFS module, vertical adjustment motor 89022080, HID bulb etc... In case of low beam failure, you will learn which parts (ballast & bulb replacement) to check and eventually to replace. If you have a burnt out bulb, just watch this video to learn how to replace the burned bulb.
