Engineered specifically for the SCANIA DC12 platform, the BOSCH 1805344 unit injector delivers precise metering and stable high-pressure injection across DC12.06, DC12.17 and DC12.02 engines operating under Euro III standards. Carrying OE references 0414701044 and 0414701066, with remanufactured option 0414701080 and nozzle DLLA150P847, this assembly is a direct fit for G380, G420, P380, P420 and R420 trucks, as well as industrial, marine and generator DC12 applications.

Manufactured to original Bosch engineering with micron-level internal tolerances, hardened steel components and wear-resistant surface treatment, the injector is built for continuous heavy-load operation, high temperature resistance and tolerance to fuel contamination. Its optimized spray pattern and accurate injection quantity support reduced fuel consumption, while lowering smoke, NOx and particulate emissions to meet demanding fleet and stationary power requirements.

For reliable installation, replace the fuel filter, clean the injector bore, inspect the cylinder head seat and fuel lines, and verify the injector code. Fit a new sealing washer, tighten to OEM torque specifications, bleed the fuel system, perform ECU calibration if required and conduct a leak test. Recommended diagnostic tools include the Bosch EPS Test Bench, EPS708, EPS815 and flow measurement equipment. Use OEM fuel filters and clean diesel fuel to maximize service life.
