Both daytime running lights have progressively changed from white to yellow and lost intensity. The discoloration began on one side and later appeared on the other, concentrated at the lower angled section of the daytime running light. There are no warning lamps, messages, or stored fault codes. Independent automotive lighting specialists who service this model describe the cause as heat from the daytime running light LED degrading the end of the clear light-guide tube inside the sealed headlamp assembly. The 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 bullet

Simultaneously, the vehicle's primary safety and convenience systems dropped completely offline, displaying synchronized, consecutive malfunction alerts for the Central Locking System, Audi Pre Sense (Distance Monitoring), Cross Traffic Assist, and Lane Change/Blind Spot Warning systems. A subsequent professional diagnostic scan confirmed that the vehic

My 2021 Audi A6 produces a strong mold and mildew odor from the HVAC/air conditioning system. The smell occurs consistently after the air conditioning is turned off and persists when entering the vehicle. The issue appears to originate from mold growth on the evaporator coil or dampers, likely caused by moisture accumulation and inadequate condensate drainage in the HVAC system. The vehicle was inspected and treated at an authorized Audi dealership; however, the treatment did not resolve the issue and the odor returned. Online owner forums and communities document the same problem across multiple Audi models and model years, suggesting this is a systemic design or manufacturing issue rather
