The throttle actuator is a common problem for all M3 vehicles with the S65 engine and E6X M5/M6 with the S85 engine. Undoubtedly, German engineering is considered the benchmark for combining design and functionality, but even the best of us make mistakes. The Throttle Actuator design has been a disaster from day one. Every single OEM unit will fail sooner than later. The failure rate of OEM units is 100%. Albeit it is not catastrophic, going into limp mode is never fun. Failure of the throttle actuator will cause the engine to go into ‘limp mode’ with the DSC and EML light illuminated on the instrument cluster. The common faults codes are: ‘2B15 – Throttle Valve Actuator Bank 1′ & 2B16 – Throttle Valve Actuator Bank 2’. 

Euro Power Motorsports Upgraded OEM+ Throttle Actuators have been the first choice for most BMW owners. With these rebuilt throttle actuators, we replace all internal components with higher-rated versions, ensuring that the actuator will not fail again and will outlive the car. We are so confident about our units that we offer them an UNLIMITED MILES LIFETIME WARRANTY. 

Price is EACH. Core Charge is also added as $200 EACH. This $200 is returned after we receive each of your stock actuators back.

• Unlimited Miles Lifetime Warranty
• Gears upgraded to superior materials made in the USA that will outlive the car
• All Mosfets replaced
• Transistors and capacitors tested
• Voltage regulator, microprocessor, serial Eprom tested or changed

The BMW S65 Engine is amazing. However, it's infamous for throttle body actuator failure. The throttle positions control the inflow of air in the engine, being directly related to the combustion. The "limp mode" is one of the main symptoms of a throttle body actuator failure. Check engine light at the panel, if it's on, it may there be a problem with your throttle position sensors.
