Code pattern and power loss under acceleration point here first.
Injector leak-off / bad injector
30%
Diesel symptoms and mechanic notes suggest this needs confirmation.
Fuel filter restriction
15%
Cheap and common enough to inspect early.
Recommended checks
- Fuel pressure test under load.
- Injector leak-off test.
- Fuel filter inspection.
- Rail pressure sensor and wiring check.
Mechanic report
Vehicle: Citroen Jumper 33MH 2.2 HDi, plate T379XZ
Problem: loss of power under acceleration.
OBD data: generic OBD may be limited on this older vehicle. Simulated scan found possible fuel-pressure-related codes and low confidence live fuel data.
AI interpretation: most likely fuel delivery issue. Possible injector leak-off, fuel pump weakness, fuel filter restriction, or rail pressure sensor issue. Needs confirmation with garage tests.
Recommended checks:
1. Injector leak-off test
2. Fuel pressure under load
3. Fuel filter inspection
4. Rail pressure sensor/wiring check
