BMW 3 Series Turbo Actuator Issues / Fault / Problems

(E90, E91, E92, E93)

Encountering a prevalent issue in BMW 3 Series diesels manufactured from 2005 to 2010, the turbo actuator fault results in sudden and intermittent power loss. The reduction in power is substantial, giving the sensation of a significant horsepower drop. Although turning off the engine temporarily rectifies the issue, it consistently returns and worsens over time.

As this fault progresses, instances of the turbo sticking increase significantly due to the in operation of the turbo actuator.

Manufacturers typically recommend resolving this issue with an entirely new turbo kit, an expensive proposition. Turbo actuators are not sold separately, forcing the purchase of a complete kit even when the existing turbo is functional.

Our solution offers significant cost savings – we can test and rebuild your turbo actuator in 2-3 working days, eliminating the need for unnecessary part purchases.
