Bosch 0414720035 Unit Injector Assembly

The Bosch 0414720035 is a Pumpe-Düse-Einheit (PDE) unit injector, also known as a Unit Injector System (UIS) component, designed for Volkswagen Group TDI pump-nozzle diesel engines. It integrates the high-pressure pump and nozzle into a single unit actuated by the camshaft, with fuel metering controlled by an electromagnetic solenoid valve. This injector serves as a direct replacement for VW Group OE numbers 038130073F, 045130073T, and 045130079X. The nozzle assembly utilizes the DSLA150P783 nozzle tip. The unit operates on 12V electrical systems standard in passenger car applications. Remanufactured units undergo full disassembly, ultrasonic cleaning, component replacement, and calibration to OEM test bench specifications including opening pressure, spray pattern, and leakage tests.
