Common Symptoms
Misfiring and idling vibrationhigh
A worn or leaking injector under/over-fuels its cylinder, causing a rough, vibrating idle.
Starting problems / hard cold starthigh
Back-leakage lowers cranking rail pressure on the DV6.
Black smokemedium
Poor atomisation from a worn nozzle or ball-seat erosion.
Poor performance / loss of powermedium
Out-of-range injector delivery triggers reduced performance or limp mode.
Check-engine light (MIL)medium
Cylinder-specific injector or rail-pressure fault codes.
Increased fuel consumptionmedium
Over-fuelling or leakage wastes fuel.
Workshop & Fitting Notes
InstallationPer Bosch, the main causes of failure are poor filtration, fuel contamination and incorrect installation - replace the fuel filter and check for water/debris before fitting.
InstallationAlways fit a new copper sealing washer and use the correct tightening torque - missing seals or over-torque are common installation faults.
MisdiagnosisRead live injector correction values to find the weak cylinder before removal rather than replacing all injectors blind.
WarningWater-in-fuel causes corrosion and ball-seat erosion - address the contamination source or new injectors will fail again.
TestingTest on a Bosch-capable common-rail bench across delivery and back-leakage points.

Is it solenoid or piezo?+
It is a Bosch solenoid common-rail injector.
What is the Bosch alternate number?+
0986435122 is the alternate Bosch number for the same injector; 0445110282 is a related alternate.
What OE numbers cross to 0445110239?+
Ford 3M5Q-9F593-HB, PSA 1980H2, Mazda Y605-13H50-B and Suzuki 15310-69K00, among others.
What are the symptoms of a failing 0445110239?+
Misfiring, idling vibration, hard starting, black smoke, loss of power, MIL on and higher fuel consumption.
Why does my 1.6 HDi vibrate at idle?+
A worn or leaking injector unbalances fuelling. Read live correction values and bench-test to confirm the faulty cylinder.
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 replace the fuel filter when fitting injectors?+
Yes - poor filtration is a leading cause of failure, so replace the filter and clear any contamination to protect the new injectors.
Should I replace one or all four?+
Diagnose each with live correction values and a bench test; on high-mileage DV6 engines failures often cluster, so check all four.
Why renew the copper washer?+
It is a one-use crush seal; missing seals or reuse cause blow-by and carbon build-up around the injector.
Does a remanufactured 0445110239 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan to meet original delivery and back-leakage specs.
0445110239 is the Bosch CRI common-rail injector fitted to the earlier PSA / Ford 1.6 HDi / TDCi production run — engine codes 9HW, 9HX, 9HV, 9HU and the Ford-side HHDA / HHDB. It pre-dates the Continental DV6C platform (which uses A2C59513556) and is found across Peugeot 207 / 307 / 308 / Partner / 1007, Citroen C2 / C3 / C4 / Berlingo, Ford Fiesta / Focus / Fusion / C-Max, Mazda 2 / 3 1.6 CD and Suzuki SX4 1.6 DDiS — predominantly 2004–2010 production. The procedure below is the workshop diagnostic flow we apply to every returned 0445110239 unit.
How a Failing 0445110239 Bosch 1.6 HDi Injector Presents
On the Bosch-supplied 1.6 HDi run, a failing injector typically presents in two distinct patterns. The first is the classic single-cylinder injector knock at warm idle, often described by drivers as a 'top-end tick' that mimics a worn cam follower. The second is a sudden hard-start episode that lasts five to ten seconds longer than normal — the rail bleeds prime overnight through a leaking injector seat. The third pattern, particular to the Bosch unit (rather than the later Continental DV6C), is intermittent stall at idle on hot restart after a short stop — caused by the seat seal failing as the unit thermally expands.
Because the Bosch 0445110239 was fitted earlier in the production run than the Continental DV6C primary, vehicles arriving at the workshop with this unit installed are usually 12-18 years old and well past 130,000 miles. The pragmatic diagnostic conclusion is that when one Bosch 1.6 HDi injector has failed, the other three are within twelve months of similar behaviour.
Vehicles and Engine Codes Using the 0445110239
Engine code coverage spans PSA 9HW, 9HX, 9HV, 9HU, 9HZ early-run and the Ford-side HHDA / HHDB / G8DA / G8DB. UK fitment includes Peugeot 1007 / 207 / 307 / 308 / 3008 / Partner Mk2; Citroen C2 / C3 / C4 / C4 Picasso / Berlingo Mk2 / Nemo; Ford Fiesta MK6 / Focus MK2 / Focus C-Max / Fusion 1.6 TDCi (HHDA / HHDB); Mazda 2 (DE) / Mazda 3 (BK) 1.6 CD; Suzuki SX4 1.6 DDiS; Mini Cooper D R55 / R56 facelift earlier production; and Volvo S40 / V50 1.6D D4164T. Production runs 2004 to 2010, with a few late 2011-build vehicles still carrying the Bosch primary.
0445110239 is not interchangeable with the later Continental A2C59513556 DV6C primary. Confirm the OE marking on the unit you are removing before ordering — if your car is a 2010-onward build with a DV6C marking on the rocker cover, it most likely runs the A2C59513556 family instead.
ECU Coding the New 0445110239 Bosch Injector
0445110239 ships with a seven-character Bosch alphabetic correction string laser-etched onto the body cap. PSA's DiagBox / Lexia and Ford's IDS / FDRS both accept the string, but the menu pathing differs: on a 9HW / 9HX vehicle DiagBox uses the 'Calibration Réglages Injecteurs' page, while IDS for HHDA / HHDB Fiesta / Fusion exposes the equivalent under 'Powertrain → Fuel injection programming'. Skipping the write-back will throw a P0263 / P0266 / P0269 / P0272 cylinder-balance fault chain inside 100 miles and the small DPF will rapidly load while the ECU runs default trim values.
On this Bosch family — distinct from the later Continental DV6C — the format is alphabetic-only seven-character (no digits in the string). Diagnostic tools that expect a sixteen-character Continental IMA will refuse the entry; tools configured for the Bosch CRI calibration table accept it cleanly. Confirm your scanner is set to the Bosch profile before attempting the write-back on a 9HW / 9HX-coded engine.
How 0445110239 Bosch 1.6 HDi Injectors Are Remanufactured
Bosch CRI 0445110239 cores arrive on a much older average vehicle than later DV6C-era cores — typical core ages are 14-18 years, and the workshop-side wear we see reflects that. Carbon build-up at the seat is heavier; the copper washer that arrives with the core is rarely re-usable. Our Bosch-specific reflow process for this part starts with a longer-than-standard ultrasonic decarbon cycle and a seat-plate replacement on roughly 30% of cores rather than the under-10% rate we see on younger Bosch 2.0d builds.
The signature stamp is a fresh seven-character flow-correction code laser-marked on the body. Because most fitters arriving at this part number are working on a high-mileage older car, we offer a discounted four-pack price with matched-set bench traces — the labour to remove the injectors only once is the saving on a 14-year-old PSA / Ford 1.6 HDi.
How do I know if I need a 0445110239 Bosch or an A2C59513556 Continental?
Read the OE marking on the unit you are removing. If it starts with 0445110... or contains 'BOSCH' on the body cap, you need a Bosch primary like 0445110239. If it starts with A2C59... or 5WS40... it is a Continental unit and you need A2C59513556 (DV6C) instead. The two are not interchangeable — even though the engine is the same.
Do I need to recode the new injector?
Yes. Each Bosch 0445110239 carries a seven-character flow-correction code that must be entered into the ECU per cylinder using PSA DiagBox / Lexia or Ford IDS / FDRS. Skipping the coding step triggers immediate cylinder-balance fault codes.
Should I replace all four on a 14-year-old car?
On a Bosch-supplied 1.6 HDi past 130,000 miles, expect the other three injectors to follow the failed unit within twelve months. Most workshops replace all four as a set on this engine because the labour cost of doing them sequentially exceeds the parts cost of replacing them together.
No injector coding is required for the Bosch unit on most applications — follow the manufacturer fitting procedure.
Replacement Advice
Always renew the copper washers / seals and bleed the fuel system before first start. Replace only the injectors your diagnosis confirms and torque fasteners to the manufacturer's published values.
