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 wastegate actuator releases excess boost pressure. A failed unit may result in a boost leak, reduced performance, and, ultimately, turbocharger failure. If your wastegate actuator has failed, replace it with this OEM part from Turner Motorpsort to restore performance and prolong engine life.

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.

If your vehicle is producing boost-related engine fault codes, it may be time to replace your diverter valve. This valve, found on the compressor housing, is designed to vent pressurized air when the throttle plate is closed, preventing compressor surge in the process.

This factory replacement unit is a "plumb-back" style, meaning the pressurized air is recirculated into the inlet for silent operation.

Compressor surge and boost-related fault codes can hurt your vehicle's powertrain. Thankfully, URO Parts offers this replacement unit designed to fix these issues.
