Wastegate Actuator for MINI

Clear BMW chassis

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.
