Common failure symptoms
On the 1.4L HDi/TDCi platform, a failing Bosch 0445110339 injector typically presents as: rough idle; misfire under light load; excess smoke; hard cold starting; limp mode with rail-pressure faults.
When two or more of these appear together, suspect the injector before peripheral systems — a comparative leak-off test and live-data cylinder-balance review will isolate the failed unit without tear-down.
When two or more symptoms appear together, suspect the injector before peripherals (EGR, glow plugs, turbo). A live-data leak-off test on each cylinder is the fastest route to the failed unit.
What Causes These Injectors To Fail
The documented failure modes on this platform are: nozzle wear causing over-fuelling; injector back-leak out of specification; carbon build-up at the injector seat causing compression leaks.
Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
How Workshops Diagnose 0445110339 Faults
Compare leak-off volumes across all four injectors to isolate the faulty unit. Keep the fuel system scrupulously clean during work — small common-rail systems are highly sensitive to debris. Clean the injector seat and fit a new sealing washer on every refit.
Never condemn a common-rail injector on a fault code alone — codes identify the circuit or cylinder, while leak-off volumes and correction values identify the component.
How Every Unit Is Tested Before Despatch
Each remanufactured 0445110339 is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is then calibrated on a common-rail test bench against the manufacturer's specification sheet — delivery, back-leak and response are all verified before the injector is sealed and despatched with its calibration data on file.
Every unit carries a 12-month parts warranty and free UK delivery.
