Bosch 0445110297 Diesel Injector

On the PSA 1.6 HDi / Ford 1.6 TDCi DV6 (9HV/9HS) platform, a failing Bosch 0445110297 injector typically presents as: chuffing / puffing noise from the injector area at idle; diesel or exhaust smell in the engine bay or cabin; black carbon (tar) build-up around an injector base; rough idle and hard starting, especially when cold; hesitation and loss of power.

When two or more of these appear together, suspect the injector before peripheral systems — a comparative leak-off test and live-data cylinder-balance review will isolate the failed unit without tear-down.

The documented failure modes on this platform are: injector seat / copper washer sealing failure allowing combustion blow-by (widely documented on the dv6); injector clamp movement letting the injector lift slightly and destroy the seat seal; injector back-leak beyond specification on high-mileage engines.

Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.

Lift the engine cover and inspect each injector base for hardened black carbon before diagnosis — blow-by is the classic DV6 failure. If a seal has been leaking for a while, clean or recut the injector seat — a new washer alone will not seal a damaged seat. Always fit a new copper washer and torque the clamp to the manufacturer procedure. Run a comparative leak-off test across all four injectors before ordering.

Never condemn a common-rail injector on a fault code alone — codes identify the circuit or cylinder, while leak-off volumes and correction values identify the component.

Each remanufactured 0445110297 is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is then calibrated on a common-rail test bench against the manufacturer's specification sheet — delivery, back-leak and response are all verified before the injector is sealed and despatched with its calibration data on file.

Every unit carries a 12 months and free UK delivery.
