Bosch 0414703004 Unit Injector – Iveco Stralis & Cursor 13 PDE

This Bosch 0414703004 unit injector (stamping PDE100S4003) is the workshop-grade replacement for Iveco Stralis and Astra heavy truck platforms running Cursor 13 and F3BE3681 engine families. It arrives as a complete pump-injector assembly, not a nozzle-only kit, which means the solenoid, metering valve, and hydraulic head are matched and bench-verified before dispatch. For diesel repair shops handling high-mileage fleet accounts, this unit eliminates the guesswork of mixing worn cores with new wear components.

This injector fits the Iveco Stralis range across 10.3L, 12.9L, and 13.0L displacements, covering model years from 2006 through 2019 depending on the chassis variant. Confirmed applications include Stralis 190S42, 190S43, 400S56, 440S50, 480, 540, and 560, plus HiWay variants 420, 480, 500, and 540 . Engine codes span the F3AE3681 series (BM, BP, BR, BS, BU, DS, DU) and F3BE3681 family (A, AM, AP, AR, AS, AU, BM, BP, BR, BS, BU, H), along with F3BEE681 variants . Astra HD9 trucks with the F3BE0681 engine also take this unit . Parts wholesalers should flag that the same physical injector body appears under multiple Iveco OEM numbers depending on the chassis serial and emissions configuration-cross-referencing by the Bosch number on the injector body itself remains the only reliable verification method.

Fitting the 0414703004 demands more than a simple unbolt-and-replace. The unit injector seats into the camshaft housing bore and is retained by a clamp; the copper sealing washer beneath the nozzle must be renewed every time, and the seat bore requires careful cleaning to prevent combustion gas blow-by that mimics injector failure. Torque the clamp bolt to Iveco specification-under-tightening allows the injector to lift under compression, over-tightening distorts the nozzle body. The electrical connector uses a push-and-latch design; shops report that a partially seated connector produces intermittent misfire codes that clear on bumpy roads. Critically, any replacement PDE unit injector requires programming of the injection quantity calibration code into the engine ECU, typically via Iveco EASY or a compatible diagnostic platform. 

For independent diesel workshops, the economic case for stocking the 0414703004 rests on fleet downtime math. A failed unit injector on a Stralis 560 or HiWay 540 takes the truck off the road; a remanufactured or poorly rebuilt core with mismatched wear surfaces often returns within months, doubling labor and towing costs. This unit comes with matched metering valve and solenoid assembly, meaning the hydraulic and electrical halves are characterized together-the failure mode where a fresh nozzle is paired with a tired solenoid body is eliminated. Return flow on a worn PDE core climbs measurably before hard failure; shops that bench-test cores know the pattern. Buying a complete, bench-verified unit injector converts a diagnostic gamble into a predictable repair. 

Q1: Can I replace just the nozzle on a 0414703004 instead of the whole unit injector?
A: The DLLA145P1517 nozzle is available separately, but the solenoid and metering valve wear together with the plunger. Nozzle-only repair on a high-mileage PDE usually restores spray pattern while leaving delivery quantity drift uncorrected. For fleet trucks, complete unit replacement is the reliable path.

Q2: The old injector had a different Iveco number stamped on it. Is 0414703004 still compatible?
A: Likely yes. Iveco superseded OEM numbers across Stralis production runs. Match the Bosch number on the injector body, not the Iveco sticker. If the Bosch reference is 0414703004 or PDE100S4003, fitment is confirmed regardless of the chassis-side OEM label.

Q3: Do I need to program a new calibration code after installing this injector?
A: Yes, if your diagnostic platform supports PDE coding. The ECU expects the delivery correction value printed on the injector. Some older Stralis ECUs tolerate default values, but drivability and emissions compliance suffer. Treat coding as mandatory on 2012+ Cursor 13 platforms.

Q4: What causes repeated injector failure on the same cylinder?
A: Check the camshaft lobe and roller follower first. A worn lobe reduces plunger stroke, and the injector compensates by extending solenoid duration until it overheats. Also verify the copper washer seat is perfectly clean-carbon buildup prevents proper heat transfer and cooks the nozzle.

Q5: Is this injector suitable for remanufacturing, or is it a throwaway core?
A: The PDE100S4003 body is rebuildable if the solenoid housing and plunger bore are within spec. Many shops core-charge and send worn units to Bosch-certified remanufacturers. If the solenoid coil is open or the body shows heat discoloration, the core has no rebuild value.
