Wastegate Actuator

Wastegate Actuator

The wastegate controls how much boost the turbocharger can produce by limiting the speed that the turbine wheel is allowed to spin. The actuator opens a valve (wastegate) and allows exhaust gasses to bypass the wheel, limiting boost to a preset level. Many earlier turbocharged BMWs use a vacuum-controlled actuator assembly, while later model F chassis and newer vehicles use an electronic wastegate actuator.

The early N55 turbocharger is notorious for pneumatic wastegate actuator failure, a common issue that triggers frustrating boost errors and persistent check engine lights. Because BMW does not provide this specific component as a standalone replacement, owners are often left with few official repair options. Pure Turbos solves this problem with an upgraded actuator engineered to fix the inherent weaknesses of the original equipment while simultaneously boosting the efficiency of the entire turbocharging system. One of the primary benefits of this enhanced actuator is its ability to deliver approximately 2 psi of additional boost compared to the factory unit while maintaining the same Wastegate Duty Cycle. By optimizing how exhaust gases are managed and bypassed, this component allows the engine to generate more power without requiring more effort from the electronics. This increased pressure translates directly into sharper throttle response and a noticeable jump in horsepower, making it an essential upgrade for drivers who want to restore their vehicle's reliability while enjoying a more aggressive and responsive driving experience.

The factory boost solenoids, also known as pressure converters, are a common issue on the M57 engine. The vacuum hose also hardens over time due to heat, and can crack or split, leading to vacuum leaks. These failures result in a loss of power, limp mode, lazy throttle response, and check engine lights. This basic kit includes two replacement boost solenoids to restore engine power and performance, plus new silicon vacuum hose that will last much longer than the OE rubber vacuum hose.
