This Genuine BMW throttle actuator replacement kit includes a pair of original BMW actuators, six original BMW mounting screws, and two original BMW linkage pull rods for a complete replacement on the S65 V8 engine on E90/E92/E93 M3 Sedan, Coupe, and Convertible (2008, 2009, 2010, 2011, 2012, 2013).

One of the few weak spots in the E9X M3 is the drive-by-wire throttle actuators. There are a number of reasons why they fail but we have found that the complete replacement is the only way to ensure the problem is fixed.

The M3 throttle valve actuators operate the individual throttle bodies on the S65 V8. There is one actuator for each bank of cylinders. When the ECU sends throttle commands to the actuators they are supposed to open or close the throttles. At first the problem seemed to be weak plastic actuator gears that would slip and spin and not move the throttles. But we have also seen problems with the electronics control board. Therefore, complete replacement is the current best course of action.

Throttle actuator failure is almost always a sudden occurrence with no warning. If you scan and clear fault codes at every oil change you might catch a hidden "soft" code (2B21, 2B25) that might hint at an impending failure. Otherwise, consider replacing both actuators on a recently-acquired used car right away or every 3-4 years as a preventive maintenance item.

Kit includes:
  • 2x Genuine BMW Throttle Body Actuators
  • 2x Genuine BMW Throttle Pull Rods
  • 6x Genuine BMW Mounting Screws
