CORE CHARGE IS REFUNDED ON RECEIPT OF YOUR OLD ACTUATORS OR WE REQUIRE YOUR OLD ACTUATORS IN ADVANCE
The throttle actuator is a very common problem for all M3 vehicles fitted with the S65 engine and E6X M5 | M6 with the S85 engine. 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’. Often the engine may run fine for around 5 minutes or so before these symptoms occur.
This throttle actuator is a common problem due to a design flaw from when the internal gears were first manufactured, causing them to wear prematurely and overload the internal electronics that control the actuator. With these rebuilt throttle actuators, we replace all internal components with higher-rated versions, therefore ensuring that the actuator will not fail again.
