Uneven idle; loss of power with rail-pressure faults; hard starting when warm; excess smoke on start-up. When two or more appear together, suspect the injector before peripherals — a comparative leak-off test isolates the failed unit without tear-down.
Piezo injector internal leak-back rising with temperature; nozzle tip coking on short-journey duty cycles; injector circuit faults from loom or connector degradation. Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
Piezo injectors must never be energised with solenoid-type test currents. Measure back-leak per bank on the V6 — both rails must be compared. Injector calibration values must be written following the manufacturer procedure after fitting. Never condemn a common-rail injector on a fault code alone.
Each remanufactured 0445115039 is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is calibrated on a common-rail test bench against the manufacturer's specification — delivery, back-leak and response verified — and despatched with a 12-month parts warranty and its calibration data on file.
The 0445115039 trusted family covers 3 verified vehicle fitments across 1 makes: Audi. Every fitment listed is registry-verified.
0445115039 cross-references 15 further OE numbers, including 0445115080, 0445115054, 0445115081, 0445115053, 0445115038, 0445115018, 0445115019 and 0986435388. Always match the reference etched on your failed unit's body.
