This Wastegate actuator, with an opening pressure of 1 bar, is designed for VAG 1.8T 20VT engines fitted with a K03 or K04-001 turbo. The actuator regulates the turbo pressure by opening the Wastegate when the set pressure is reached. Thanks to the higher opening pressure, this actuator is suitable for tuned engines or those with higher turbo pressure.
