This is a used OEM Audi relay plate / holder, part number 4G1937503A. Removed from a donor vehicle, this left-side relay plate serves as the mounting and connection point for electrical relays in the engine bay or fuse box area. When the original relay plate fails, it can cause intermittent power loss to critical systems like the fuel pump or cooling fans, leading to no-start or overheating conditions. This genuine part restores the proper relay seating and circuit continuity.
