0445110273

The 0445110273 carries the Fiat/Iveco OE reference 504088755 (also printed as 504 0887 55). For New Holland tractor applications, the equivalent OE is 504377671 or 500371920. For UAZ Patriot 2.3 D, the same 0445110273 fits with the platform code F1AE0481B stamped on the cylinder block. The 0445120011 is the earlier 0445120-series generation for the same F1AE0481 2.3L engine (Fiat Ducato 2.3 JTD 2002-2006, Iveco Daily 2.3 2002-2007) - same displacement, different IMA calibration, NOT interchangeable. To verify, check the engine code stamped on the cylinder block — F1AE0481 is the 2.3L Multijet indicator; F1AE0481C/D/N/T variants are all valid for this SKU.

The 0445110273 is fitted with the Bosch F00VC01338 solenoid control valve (Bosch F00VC01xxx series, CRI2/IPS19 generation). This valve is the same control valve group used on the sister SKUs 0445120011 (the same F1AE0481 2.3L engine, the earlier 0445120-series generation) and 0986435165 (Bosch aftermarket exchange number). The valve stamping is found on the solenoid connector cap. For F1AE0481 Multijet 2.3 JTD platforms the F00VC01338 calibrates the HP rail pressure at 1600 bar peak for Euro 4 emissions compliance.

The 0445110273 and 0445120011 are sister SKUs that share the same F00VC01338 control valve group, and both serve the same F1AE0481 2.3L engine (F1AE0481). They differ by injection generation: 0445110273 belongs to the 0445110 series (Fiat Ducato 2.3 Multijet 2006-2014, Iveco Daily 2.3 2006-2014, UAZ Patriot 2.3 D), while 0445120011 is the earlier 0445120-series generation (Fiat Ducato 2.3 JTD 2002-2006, Iveco Daily 2.3 2002-2007). The two are NOT fully interchangeable because their IMA calibration data differs - fit the wrong one and the ECU misfuels regardless of displacement. The 0986435165 is the Bosch aftermarket exchange number for the 0445110273 2.3L F1AE Multijet injector.

The 0445110273 fits the F1AE0481 Multijet 2.3 JTD platform: Fiat Ducato 2.3 D Multijet (100/120/130 Multijet, 2006-2014), Fiat Doblo 1.9 JTD / 2.3 Multijet (2004-2010), Iveco Daily III/IV 2.3 D (35S / 50C / 65C variants, 2006-2014), Iveco Daily V/VI 2.3 D (2014-2022), UAZ Patriot 2.3 D (2009-2016), New Holland tractor T5000 / T6000 series 2.3 D (2006-2014). Note the generation split within the 2.3L F1AE: this 0445110273 covers the 2006-2014 builds, while the 2002-2006 builds take 0445120011. Iveco Daily 3.0 D / Iveco Massif 3.0 (F1C 3.0L) use a different injector family entirely. Source: italianvehicles.co.uk field case + dieselcatalog.online.

Common failure symptoms on F1AE0481 Multijet 2.3 JTD: (1) OBD fault codes P0201-P0204 — injector circuit malfunction on cylinders 1-4, with P201C / P201D for IMA calibration errors on the F00VC01338 valve; (2) white smoke on cold start followed by black smoke under acceleration — typical of an atomization issue with the DLLA142P1595 nozzle; (3) rough idle on cold start, with the engine miscounting cylinders 2 or 3; (4) fuel consumption increase of 12-18% with a typical return-flow signature; (5) excessive return flow at idle > 80 mL/min confirms internal valve degradation. Diagnose on a CRD-700 / EPS200A test bench, then a Fiat Multijet OBD scan-tool cut-out test before condemning the injector. Source: italianvehicles.co.uk field case 2019.

Three torque locations on the F1AE0481 Multijet 2.3 JTD platform: (1) High-pressure fuel line banjo bolt (rail side): 22-25 N·m with a dedicated 14 mm or 17 mm flare nut wrench; NEVER use an impact wrench — shock loading deforms the F00VC01338 valve assembly and causes a no-start; (2) Injector hold-down bolt: 18 N·m + 60° angle (Bosch CRIN standard; verify against Fiat/Iveco workshop manual); (3) Feed tube union nut: 1.5 N·m (13 in·lb) — very light torque, overtightening cracks the injector body. Tools: 14/17 mm flare nut wrench, 10/12 mm sockets, calibrated 3-30 N·m torque wrench. Always fit new copper sealing washers + new O-rings.

Yes. The 0445110273 is a complete solenoid common rail injector with cylinder-specific IMA values stored in the engine ECU. After installation, use the Fiat Multijet scanner (or compatible aftermarket scanner with F1AE coverage, e.g. iCarsoft i930, Autel MaxiDAS) to code the injector's IMA values. Common installation mistakes: (a) installing the injector without coding, resulting in cylinder imbalance, rough running, and persistent P201C / P201D codes; (b) entering wrong cylinder number — double-check which cylinder the failed injector was in before coding (the F1AE is an inline-4, cylinder numbering starts at the front of the engine, drive-end side); (c) using the wrong IMA value — the IMA code for the 0445110273 is on the injector label and must be entered to 0.01 mg/stroke precision.

Standard aftermarket warranty is 12 months from date of purchase, covering manufacturing defects only (no atomisation, no electrical continuity, or > 80 mL/min return flow at 200 bar bench test). Return conditions: (1) manufacturing defect confirmed by bench test; (2) incorrect fitment confirmed before installation — if the injector does not match the build plate OE (504088755 / 504377671) or the engine platform (F1AE0481); (3) physical damage in shipping. Non-returnable conditions: (1) installed and coded to ECU; (2) damage from fuel contamination (water, debris, algae); (3) over-torqued HP banjo bolt cracking the injector body; (4) cross-installed on a different injection generation (0445110 vs 0445120 series).

Three frequent mistakes: (1) Confusing with 0445120011, which also serves the F1AE0481 2.3L but is the earlier 0445120-series generation (Fiat Ducato 2.3 JTD 2002-2006, Iveco Daily 2.3 2002-2007). Same valve group, same 2.3L displacement, DIFFERENT IMA calibration. Verify the build year and the injector series stamped on the body before ordering. (2) Confusing with 504341404 / 5801479929 (the Iveco D-series alternative) — these are for different Multijet generations and use a different control valve group. (3) Buying 0986435165 (aftermarket exchange) when the original 0445110275 / 0445110273 cal was the OEM spec — the aftermarket exchange will install correctly but the IMA code stamped on the solenoid body may differ. Always verify the OE stamping on the engine build plate first.
