Engine Intelligence

Fiat / Alfa / Vauxhall 1.9 JTD & CDTI 16v 150 (Z19DTH — Vectra, Astra, 159, Bravo) 192B1000

Common symptoms

Misfire or judder, often between 1,500–2,200 rpm
Rough idle with the engine management light on
Intermittent single-cylinder faults that come and go
Limp mode / reduced power
Black smoke under load

Documented failure modes

Injector wiring / connector faults logging single-cylinder circuit codes (a documented weak point on this engine — especially injector 3)
Injector back-leak beyond specification
Nozzle wear causing over-fuelling and smoke

Diagnostic guidance

On a single-cylinder circuit code, inspect the injector plug and loom first — wiring faults on this engine routinely mimic a failed injector
If several injector codes appear together, suspect a supply/loom or ECU driver fault rather than multiple simultaneous injector failures
Clear codes and confirm which returns first before replacing hardware
Run a comparative leak-off test to separate electrical from hydraulic faults

Bosch 0445110391 1.9 JTDM/CDTi 16v (150hp) Common Rail Injector (Alfa/Fiat/Vauxhall/Saab)

AI Technical Summary

Bosch solenoid common-rail injector for the higher-output 16-valve 1.9 JTDM/CDTi/TTiD (150 hp) engine across Alfa Romeo, Fiat, Vauxhall/Opel and Saab. Bosch exchange 0986435104; OE Fiat/Alfa 55221020 and 55198218. Replacements are coded to the ECU via the injector correction value. Failures are driven by poor fuel filtration, contamination and back-leakage. Key symptoms: Rough idle / vibration; Hard starting; Loss of power / limp mode; Black smoke. Common failure modes: Internal wear / high back-leakage; Water-in-fuel corrosion; Nozzle coking.

Common Symptoms

Rough idle / vibrationhigh

A leaking injector unbalances cylinder fuelling on the 1.9 16v.

Hard startinghigh

Excess back-leakage drops cranking rail pressure.

Loss of power / limp modehigh

Out-of-range delivery or rail-pressure deviation cuts power.

Black smokemedium

Poor atomisation over-fuels the cylinder.

Engine management lightmedium

Cylinder-specific injector or fuel-metering codes.

Workshop & Fitting Notes

InstallationCode the injector correction value to the correct cylinder with the relevant diagnostic (Fiat MES / Vauxhall MDI / Saab Tech2) before road test.
InstallationRenew the copper combustion washer and leak-off seals; torque the clamp to spec.
MisdiagnosisThis is the 16v 150 hp injector - do not confuse with the 8v 0445110276; confirm the engine code and OE number.
WarningFix contamination (filter/water/debris) first - the 1.9 16v is sensitive to fuel quality.
TestingBench-test across delivery and back-leakage points; verify spray pattern before refit.
