Engine Intelligence
Hyundai / Kia 1.6 CRDi (D4FB — i30, ix35, Cee'd, Sportage) D4FB
Common symptoms
- Rough idle that may smooth out at higher revs
- Knocking or ticking at idle or under light load
- Hard cold starts, occasionally hard hot starts
- Black smoke under acceleration or load
- Reduced power, hesitation or limp mode as the fault worsens
Documented failure modes
- Injector correction values drifting to their compensation limit
- Injector coding loss after previous work — rough running and knock without a clear stored fault
- Injector back-leak beyond specification affecting rail pressure
Diagnostic guidance
- Verify injector coding first — lost or wrong codes cause knock and rough running with no stored fault on this engine
- Read injection correction values: a unit at its compensation limit identifies the failing injector
- DPF, EGR and fuel-supply restrictions mimic injector faults on the 1.6 CRDi — rule them out before replacing hardware
- Register the new injector code after fitting per the manufacturer procedure
Fitment note: The D4FB ran across many model years and outputs with different Bosch references — always match the reference etched on the injector body, not just the engine code.
Why this injector?
- Fits the D4FB engine code used in the Hyundai I30 and related diesel variants.
- Bosch diesel injector — flow-tested and calibrated on common-rail equipment before despatch.
- Commonly specified when investigating rough idle, injector knock, smoke or poor fuel economy on D4FB engines.
- 12-month warranty, free UK delivery and a £20 refundable core deposit per injector (refunded after we receive and inspect your old unit — return it within 30 days).
