S65 E90 E92 M3 Throttle Body Actuator 13 62 7 838 085
These throttle actuators have been a common failure item on the V8 M3. We suggest replacing both if you have had one fail. The plastic gears inside wear out over time so if one actuator has failed it is likely the second one will fail in the near future. We suggest lubricating throttle linkages thoroughly when replacing these.
