What are the symptoms of a failing 0445110255?
Hard starting, rough idle and vibration, black smoke, loss of power or limp mode, the engine-management light, and higher fuel consumption.
Why does my 1.5 CRDi vibrate at idle?
A worn or leaking injector unbalances fuelling. Read live correction values and bench-test to confirm the faulty cylinder before replacing.
What causes these injectors to fail?
Per Bosch, poor fuel filtration, fuel contamination (including water) and incorrect installation - so fix the cause, not just the injector.
Do I need to code the injector to the ECU?
Yes. Each injector has an individual IMA flow-correction code that must be written into the ECU after fitting, or the engine will run on default trim and may log cylinder-balance faults.
Should I replace one or all four?
Diagnose each with live correction values and a bench test; on high-mileage 1.5 CRDi engines failures often cluster, so check all of them.
Why renew the copper washer?
It is a one-use crush seal; a missing or reused washer causes blow-by and carbon build-up around the injector.
Does a remanufactured 0445110255 perform like new?
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan to meet original delivery and back-leakage specifications.
