This used genuine OEM Servotronic Relay # 642 (8E0907307C) was removed from a donor Audi RS4. Also known as the servotronic relay, it controls variable power steering assist on the 4.2L V8 (4163cc or 4172cc). A failing relay can cause intermittent loss of steering assist or a sudden change in steering effort.
