| Bosch Part Number | 0 414 720 215 (0414720215) | Often printed directly on the injector body. |
| OEM / VAG Part Number | 038 130 073 B or 038 130 073 C | Critical for 2003-2005 models; verify the revision letter. |
| Injector Type | Solenoid Valve Unit Injector (Pumpe-Düse / PD) | Mechanically actuated by camshaft, electronically controlled. |
| System Pressure | Up to 2,050 bar (approx. 30,000 psi) | Pressure varies with engine RPM (cam-lobe dependent). |
| Nozzle Design | VCO (Valve Covered Orifice) or Hole-type | Typically 5 or 6 injection holes. |
| Electrical Resistance | 0.5 Ω (Ohms) or less (Very Low Impedance) | Peak & Hold (Saturation) driver design. Do not connect directly to 12V. |
| Opening Voltage | Approx. 40V - 50V (Boosted Voltage) | The ECU uses a voltage "boost" to open the solenoid quickly. |
| Flow Rate (Quantity) | ~ 300 - 340 ml/min (at specific test pressure) | Calibrated for stock 75 HP output. Must be balanced within 0.5 mg/stroke. |
| Spray Angle / Pattern | Conical / Swirl-optimized | Designed for the pre-chamber (swirl chamber) combustion method. |
| Tightening Torque | 15 Nm + 180° (Angle-tightened) | Critical: New stretch bolts are required. Incorrect torque destroys the injector or head. |
| Engine Code | AMF or BHC | Verify before purchase. |
| Cylinder Count | 3-Cylinder Application | Specific to the 1.4 TDI (3cyl), not the 1.9 TDI (4cyl). |
