Audi wastegate actuator Description

Vehicle Application: Replaces A3 9 TDI (8L) 110/115/130/150 HP; replaces Seat Alhambra Leon Ibiza 9 TDI; replaces Bora 9 TDI; Galaxy 9 TDI, etc. replacement. 2 OEM Number: 038253019D, 038253019DX, 038253019DV, 038253019N, 038253019NX, 038253019NV, 03G253014E, 1121159, YM219G438BA, 1135819, YM219G438AA, 038253019EX, 038253019C, 038253019CX, 038253019CV, 038253019A, 038253019AX, 038253019AV, 03G253O14R, 03G253O14K. 3 Function: The wastegate actuator controls the boost power of the turbine by diverting excess exhaust gas away from the turbine wheel. It consists of a spring and a diaphragm. The spring holds the wastegate closed until the boost pressure reaches a set level, then opens, allowing the gases to escape and reducing the boost pressure. 4 High efficiency: The actuator controls the speed of the turbine, preventing it from spinning too fast, and regulates the speed of the compressor. It helps protect the turbocharger from unnecessary wear by limiting the maximum boost level of the turbocharger to a safe level. 5 Ideal replacement: Over time, pressure and heat will take their toll, which can weaken the spring and open the wastegate prematurely, reducing the boost level and efficiency of the turbine. The diaphragm can also fail, meaning the valve will no longer open and damage the engine.
