manufacturer does not sell that LED board or light guide separately, so the only available repair is replacement of the entire headlamp assembly. A manufacturer technical service bulletin covering this model and model year treats daytime running light color variation as a normal characteristic and states that no repair is to be performed, and no recall or warranty extension has been issued for this condition. The headlamps are available for inspection upon request. Safety risk: the daytime running lights are losing output and conspicuity gradually rather than failing outright, so the driver receives no warning and other road users see a vehicle with degraded daytime visibility.

System, Audi Pre Sense (Distance Monitoring), Cross Traffic Assist, and Lane Change/Blind Spot Warning systems. A subsequent professional diagnostic scan confirmed that the vehicle's Engine Control Unit (ECU) has hard-logged active manufacturer fault codes P310A (Low Fuel Pressure Regulation - Fuel Pressure Fluctuates) and P310B (Low Pressure Fuel Regulation - Fuel Pressure Outside Specification). These synchronized electrical and drivetrain failures occur intermittently, yet have specifically occurred multiple times following exposure to moisture, including rainfall, winter slush, and standard car washes. The identical electrical system dropouts were officially reported to two authorized Audi dealership service centers during its active warranty window, but the underlying system failures remain uncorrected, leaving a recurring safety hazard unaddressed.
