BMW X3 Turbo Actuator faults
The BMW X3 2.0D from 2004 to 2007 is fitted with an electronic turbo actuator, which is designed to accurately control the flow and output of the turbocharger. The actuator is controlled by the Engine ECU and the parameters of the ECU can be adjusted to change the way the actuator operates. If tuned correctly, you can decrease the spool up time of the turbocharger and simultaneously increase the power and economy of the vehicle.
Electronic turbo actuators are very common failing parts and are not sold separately from the turbo. So when the electronic turbo actuator does fail, you are quoted by the dealers for a complete replacement turbocharger + actuator together. Used parts are not recommended due to how common the actuator failure is and also used parts will require coding to the vehicle at an additional cost.
BMW X3 Electronic Turbo Actuator Failure Symptoms
A faulty turbo actuator can sometimes be very easy to diagnose, however sometimes the diagnostic equipment can point you in the direction of a boost pressure sensor or give descriptions like “Boost Leak Detected”. Therefore it is necessary to ensure you thoroughly diagnose the problem before you start replacing components. Below is a short list of common failure symptoms we see with the electronic turbocharger actuator.
- Loss of power under acceleration
- Intermittent loss of power under acceleration
- Smoking on acceleration
- Fault codes pointing to turbo actuator
- “Charge Air Pressure Control” fault
- Actuator arm not moving
The most common part numbers associated with the BMW X3 Electronic Turbo Actuator are: 712120 & 6NW008412.
BMW X3 Electronic Turbo Actuator Repairs
