Quick Diagnosis
If your DV6TED4 engine shows:
- rough idle
- hard starting
- white or black smoke
- knocking or ticking noise
- reduced fuel economy
A faulty injector may be the cause. Continue below to confirm symptoms and solutions.
Can You Drive With This Problem?
Driving short distances may be possible, but continued use can cause:
- piston damage
- turbo contamination
- fuel dilution of engine oil
- catalytic converter damage
Prolonged driving may lead to major engine failure.
Typical Repair Costs (UK)
Average costs for injector-related repairs:
£180 - £350
Per Injector
£700 - £1,200

£120 - £300
Labour
Early replacement prevents costly engine damage.
Common Injector Failure Symptoms
Owners frequently report:
Rough idle and engine vibration
The small-capacity engine is sensitive to injector imbalance.
White/blue smoke
Injector leakage causes unburnt fuel to reach the exhaust.
DPF issues (where fitted)
Poor combustion accelerates DPF soot loading.
Engine management light
Injector fault codes P0201-P0204 commonly logged.
Fault Codes Linked to Injector Issues
Common diagnostic codes include:
How to Diagnose DV6TED4 Injector Faults
Follow this step-by-step testing approach to identify the faulty injector:
- 1
Read fault codes
Connect an OBD-II scanner and note any injector-related codes (P0201–P0204, P2146, P2149). This identifies which cylinder is affected.
- 2
Perform a leak-off test
Disconnect the fuel return pipes and route into measuring containers. Run the engine at idle for 60 seconds. Compare volumes per cylinder against manufacturer spec.
- 3
Listen for injector tick
Use a mechanic's stethoscope on each injector body. A dead or irregular tick indicates a stuck or failing solenoid.
- 4
Check fuel rail pressure
Monitor live fuel rail pressure data via diagnostic tool. Low pressure can mimic injector symptoms and may indicate a fuel pump issue instead.
- 5
Inspect for external leaks
Check around injector seals for signs of fuel or combustion gas leakage. Black carbon deposits indicate a blown seal.
- 6
Cylinder balance test
Use diagnostic software to run a cylinder contribution test. This electronically disables each injector in turn to measure its effect on engine speed.
Why DV6TED4 Injectors Fail
Common causes include:
- fuel contamination
- high-pressure wear cycles
- carbon buildup
- poor fuel quality
- internal valve wear
Professional remanufacturing restores spray pattern and pressure accuracy.
When Replacement Is Required
Injector replacement is recommended if:
- leak-off test fails
- misfire persists after coding
- excessive return flow detected
- spray pattern fails testing
- vehicle enters limp mode
DV6TED4 Repair Advice
The DV6 uses Bosch solenoid injectors. IMA coding is required via Diagbox (PSA), Ford IDS (Ford), or VIDA (Volvo) depending on the vehicle brand.
Remanufactured (Recommended)
OEM-spec rebuild with new nozzles, seals, and solenoids. Full flow testing. 12-month warranty. 40–60% less than new.
Brand New OEM
Factory-fresh from Bosch, Delphi, or Siemens. Highest cost but zero previous wear. Best for low-mileage vehicles.
