Throttle Valve Repair Kit – VAG 1.4 / 1.9 / 2.0 / 2.5 / 2.7 / 3.0 / 4.2 TDI | OEM A2C59512933
The throttle valve on VAG TDI engines uses a plastic actuator gear that wears and strips over time — causing the throttle flap to stop responding, fault codes (throttle actuator position), and limp mode. This repair kit replaces the broken gear, restoring full throttle valve function without replacing the entire unit.
