VLTA assesses eligible internal DRL modules, LED boards and light-guide faults after the reported symptom and headlight have been identified.
A dim, yellow, intermittent or failed DRL may originate from different components. VLTA confirms the supported repair path after assessment.
The 2016 Audi A3 Quattro pair record documents replacement DRL modules and light tubes, resealing, in-vehicle DRL operation without dashboard warning codes and a pressure-test pass. The 2017 A3 record distinguishes customer-reported operation from workshop in-vehicle testing.
Both Audi Q7 headlights received DRL LED boards/modules, light tubes and outer lenses, then passed pressure testing. No electrical bench or in-car test was performed because the vehicle was unavailable. The Velar left headlight received DRL modules and an outer lens, with no light-tube replacement; its pressure and in-car checks passed.
DRL component work does not establish vehicle coding, camera calibration or ADAS calibration capability.
VLTA uses VLTA-supplied parts, requires the headlight to be removed for internal repair and water-ingress work, does not offer an external-only reseal, and does not claim vehicle-mounted camera or ADAS calibration. Suitability, freight, price and timing are confirmed for the individual job.
