Lightning-related phenomena are known to interact with and influence all detector systems of the Pierre Auger Observatory in Argentina. Notably, the Surface Detector has recorded signals linked to Terrestrial Gamma Flashes (TGFs) which are rare phenomena linked to the initial processes of lightning. Interpreting these signals remains challenging due to the absence of a system capable of providing detailed 3D imaging of lightning propagation. To address this gap, we are developing a state-of-the-art interferometric lightning detection system that enhances the Observatory's unique capabilities for precision research on TGFs. It will consist of radio detectors that have been previously developed for the Auger Engineering Radio Array (AERA), located at strategic positions within the Auger field. This contribution highlights recent hardware developments and the initial large-scale data readouts from the first field installation, demonstrating the system's potential for advancing TGF and lightning research.
