Installation must be performed by a professional. After fitting, a throttle body relearn procedure is required to recalibrate the throttle body position sensor baseline — this is standard throttle body service practice for VAG 1.4 TSI platforms. Non-professionals should not attempt installation, as improper fitting may result in throttle body malfunction. The instruction manual included in the package is for professional reference only.
