Common failure symptoms
On the 1.3L CDTi/Multijet platform, a failing Bosch 0445110326 injector typically presents as: hard cold starting; rough idle; excess smoke; cylinder misfire codes; poor fuel economy.
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: injector seizure in the head from carbon build-up on high-mileage units; nozzle wear causing over-fuelling; combustion leaks past the injector washer.
Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
How Workshops Diagnose 0445110326 Faults
Soak injector bores before removal on high-mileage engines. Clean seats fully and fit new washers before installing replacements. Injector codes must be registered following the manufacturer procedure after fitting.
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 0445110326 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.
