Engine Intelligence
PSA / Ford / Volvo 2.0 HDi / TDCi / D (DW10 — Siemens piezo) QXBA
Common symptoms
- Hard starting when warm / extended cranking
- Rough idle immediately after start
- Loss of power with rail-pressure faults (limp mode)
- White smoke on start-up
- Engine cutting out when hot
Documented failure modes
- Piezo injector internal leak-back rising with temperature
- Rail pressure failing to build during hot cranking
- Injector back-leak overwhelming high-pressure pump delivery
- Wiring/connector chafing causing injector circuit faults
Diagnostic guidance
- Measure injector back-leak (leak-off) both cold and fully warm before condemning — this family's leak-back typically worsens with temperature
- Compare requested vs actual rail pressure during cranking in live data
- Piezo injectors must never be energised with solenoid-type test currents
- Fit new sealing washers and follow the manufacturer classification/coding procedure after replacement
Fitment note: This Siemens/Continental piezo family spans PSA (RHR/RHF…), Ford (QXBA/UFBA…) and Volvo (D4204T) builds of the same 2.0 engine — always confirm the part number etched on the injector body before ordering.
Why this injector?
- Fits the QXBA engine code used in the Ford MONDEO 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 QXBA engines.
- 12-month warranty, free UK delivery and a £20 refundable core deposit per injector (refunded when your old unit is returned).
