For an Audi with servotronic power steering, this used genuine OEM Servotronic Relay #628 (4B0907307B) was removed from a donor vehicle. The relay controls variable power-steering assist, adjusting effort based on speed. A failing relay can cause sudden loss of assist or inconsistent steering feel.
