What are the symptoms of failure?
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML, usually from one or more leaking injectors.
Why does my 1.9 dCi run rough or smoke?
A worn or leaking injector unbalances fuelling; read live back-leakage data and bench-test the suspect cylinder before condemning the set.
What causes these injectors to fail?
Poor fuel filtration, contamination, water-in-fuel and back-leakage wear - fix the cause first or the new injector will fail again.
Does a remanufactured 0445110146 perform like new?
A properly remanufactured injector is bench-tested and recalibrated to the Bosch CRI1 plan; because no coding is required it can simply be fitted with new seals and road-tested.
