Common failure symptoms
- Single-cylinder injector knock that becomes more pronounced as the engine warms.
- Excessive cold-start smoke that clears within ~30 seconds.
- Hard hot-restart after the engine has soaked overnight.
- Measurable loss of fuel economy paired with DPF over-fuelling and forced regenerations.
- Limp-mode events triggered by cylinder-balance or rail-pressure deviation faults.
- Injector coding faults logged after replacement when the new flow-correction code is not written into the ECU.
When two or more symptoms appear together, suspect the injector before peripherals (EGR, glow plugs, turbo). A live-data leak-off test on each cylinder is the fastest route to the failed unit.
