A used Audi Servotronic Module Relay # 605, OEM part number 4D0907307A, also replaces 4D0907307. This relay controls the servotronic power steering system's variable assist, adjusting steering effort based on vehicle speed. When it fails, steering may feel heavy at low speeds or inconsistent. It's a genuine used part from a donor vehicle, ready for installation.

The servotronic system in your vehicle provides less steering assistance at higher speeds.
