Original BMW Electronic Throttle Actuator for BMW M3 E90, E92, and E93 S65 V8 (2008–2013)

The Original BMW electronic throttle actuator moves the individual throttle bodies on the S65 V8 in the 2008–2013 BMW M3. On any electronic throttle system, a motor like this positions the throttle valves on command from the engine control unit instead of through a cable from the accelerator pedal. BMW names the part simply Actuator and shows it in production from June 2007 onward. Each unit weighs 1.3 kg (2.8 lb), is made in Germany, and is sold as a single piece. In BMW's parts data it belongs to the throttle body group for the E90, E92, and E93 M3, the same group that holds the throttle bodies it drives.

Original BMW Parts carry a 24-month parts warranty.

Throttle actuators are a known failure item on higher-mileage S65 V8s. Fault codes for this system are reported separately for bank 1 and bank 2. BMW's throttle body diagram for these cars shows the actuator alongside the individual throttle bodies, the throttle body lever, the throttle body clips, and the connector, sockets, and socket contacts in the wiring that feeds it. Each of those neighbors carries its own BMW part number in the diagram.

Common Questions

Which fault codes point to a failing throttle actuator?
The codes most often associated with it are 2B15 and 2B16 (throttle valve actuator governor monitoring/control, bank 1 and bank 2), 2B21 and 2B22 (throttle valve actuator pre-drive check, bank 1 and bank 2), and 2B25 and 2B26 (throttle valve monitoring, bank 1 and bank 2).

Is the same actuator used on both banks of the engine?
The S65 uses two throttle body actuators per car. Check the fitment table and send us your VIN so we can confirm the correct part number for each position.
