Audi Q5 S-Line 8R Headlight Assembly 8R0941004AG - Used Original Parts

Diagnosis and Common Symptoms

The Audi Q5 8R headlight assemblies are highly susceptible to seal degradation over time, which leads to micro-cracks, heavy condensation, and eventual water ingress. This moisture typically pools at the bottom of the housing, shorting out the Xenon ballasts and the LED daytime running light (DRL) control modules. Common physical symptoms include the signature DRL strip turning yellow, dimming, or burning out entirely, as well as flickering or completely dead low beams. On the dashboard, this will trigger "dipped headlight" or main beam malfunction warnings. When scanning the vehicle's Central Electronics module with VCDS or ODIS, technicians will frequently find fault codes such as 00978 (Lamp for Low Beam Left/Right) or 02895 (Supply Voltage for LED Module).
