28348371 is supplied as a remanufactured replacement injector. Cross-reference numbers: 28348371, 28342997, A6510700587, A6510704987. In a common rail system the injector is the component that actually controls combustion. It holds back fuel at rail pressure and lifts for only a few milliseconds at a time, metering the exact quantity and breaking it into a fine spray so the charge ignites cleanly. When delivery drifts, the engine does not usually stop — it simply starts to burn fuel badly. Watch for hard hot starting, uneven idle, visible smoke, a misfire that clears when the engine is revved, and consumption creeping up without any change in operating conditions. Do a return-flow check before buying anything. Comparing leak-off volumes between cylinders takes minutes, and if one injector returns far more than its neighbours, that single test has answered the question. Installation notes: new copper washers and seals are mandatory, the seat must be clean and undamaged, and the retainers should be torqued to the engine manufacturer's specification. If the ECU stores injector codes for this engine, program them after fitting, otherwise the engine will not compensate correctly. Our rebuild standard: strip to components, clean, measure against wear limits, replace what is worn, machine back to specification where required, then calibrate and bench-test every unit. Delivery, return flow, opening pressure and leakage are recorded, and units outside specification are not dispatched. Test sheets available on request, and every unit carries a 12-month warranty.
