The Bosch 0414720037 is a pump-nozzle unit injector (PDE/UIS) designed for Volkswagen Group 1.9 TDI Pumpe-Düse diesel engines. It integrates the high-pressure pump and nozzle into a single unit actuated by the camshaft. The injector utilizes a DSLA150P800 nozzle (Bosch 0433175304) with five spray holes for optimized combustion. The solenoid valve controls injection timing and quantity via the engine control unit. This unit replaces multiple OE part numbers across VW, Audi, Seat, and Skoda applications. Remanufactured units undergo full disassembly, component inspection, nozzle replacement, and calibration to OE specifications on Bosch test benches.
