Audi A4 B8.5 Left Headlight Assembly 8K0941005D - Used Original Parts

Diagnosis and Common Symptoms

On the Audi A4 B8.5, left headlight faults typically surface through the onboard diagnostic system rather than a hard fault code first. Common complaints include the left low beam or DRL strip failing intermittently, condensation build-up inside the lens indicating a cracked or warped housing, and uneven light output compared to the right side after a collision repair. Where the vehicle is fitted with Xenon/Bi-Xenon or AFS (Adaptive Front Lighting), a failing ballast or control unit inside the assembly can trigger a "Check Headlight Range Control" or "Xenon Headlight Left Malfunction" message on the dash, sometimes accompanied by fault codes in the 01184 or 01197 range under the Lighting module. Physical impact damage, yellowed/cracked lenses, or failed adjustment motors are the most frequent reasons owners replace this unit rather than attempt repair.

Introduction

This listing is for a Genuine Used left headlight assembly, part number 8K0941005D, removed from an Audi A4 B8.5 during dismantling. Every unit passes a bench-test cycle confirming operation of the low beam, high beam, DRL, and turn signal circuits before listing. Sourcing a Genuine Used headlight avoids the fitment and lens-clarity inconsistencies common with aftermarket reproduction units. Stock is inspected for lens condition, housing integrity, and connector condition prior to sale.
