Bosch 0445110188 Diesel Injector

On the 1.6L HDi/TDCi platform, a failing Bosch 0445110188 injector typically presents as: rough idle and hesitation when cold; excess black smoke under load; loss of power / limp mode; repeated dpf regeneration problems; individual cylinder balance corrections in live data.

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: nozzle carbon build-up from short-journey duty cycles — the dv6 is widely documented as sensitive to servicing and carbon build-up; injector back-leak beyond specification; injector seat carbon causing sealing problems on refit.

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

Clean injector seats carefully before fitting — carbon in the bore is a common cause of repeat leaks on the DV6. Test leak-off return volumes comparatively before condemning an injector. Injector coding is required after fitting on coded variants — follow the manufacturer procedure.

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 0445110188 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-month parts warranty and free UK delivery.

The 0445110188 trusted family covers 12 verified vehicle fitments across 5 makes: Peugeot, Citroen, Ford, Volvo and Mazda. Every fitment listed on this page is registry-verified — no scraped or assumed applications.

0445110188 supersedes or cross-references 24 further OE numbers, including 0445110136, 0986435090, 1980H3, 1980E5, 1980CS, 96466862, 96485754 and 96507606. Always match the reference etched on your failed unit's body — cross-references within a family are verified equivalents, but etched numbers remain the source of truth.
