Description

A practical 3D-printable replacement gear for the throttle body actuator on Volkswagen Passat 1.6 petrol models. The small plastic gear inside the throttle body can wear, crack or lose teeth. Instead of replacing the complete and considerably more expensive throttle body assembly, this model allows you to replace the damaged gear itself. A useful repair solution for restoring the throttle actuator mechanism while keeping the original throttle body. 🚘 COMPATIBILITY The exact compatibility depends strongly on the Passat generation, engine code and throttle-body version. A confirmed application for this type of throttle-body gear is: Volkswagen Passat B4 / 35i (3A2) 1.6 — 101 HP / 74 kW Volkswagen Passat Variant B4 / 35i (3A5) 1.6 — 101 HP / 74 kW Replacement-gear listings specifically identify these applications for the throttle body referenced as 037 133 064 D. ⚠️ IMPORTANT Do not assume that every Volkswagen Passat 1.6 uses the same gear. For example, the later Passat B5 1.6 AHL uses a throttle-body assembly with OEM 058 133 063 H, while later 1.6 engines use still other throttle-body designs. Compare your original gear and throttle-body number before printing. 🔢 RELATED OEM / REFERENCE NUMBER For the confirmed Passat B4 1.6 application: VW throttle body reference: 037 133 064 D 037133064D This is the reference for the complete throttle-body/control-valve assembly, not an OEM number for the individual printable gear. The gear itself generally isn't catalogued by Volkswagen as a separate service component. ⚙️ WHAT THIS MODEL REPAIRS A damaged actuator gear may prevent the internal throttle mechanism from operating correctly. Instead of replacing the entire assembly: ✔ Open the actuator housing ✔ Remove the damaged gear ✔ Install the printed replacement ✔ Reassemble the throttle body ✔ Check free movement before installation This can turn an otherwise expensive component replacement into a very small repair. 🖨️ RECOMMENDED PRINT SETTINGS Because this is a small
