Which engines use the Bosch 0445110414 injector?

0445110414 is verified for the Renault/Vauxhall 1.6 dCi R9M platform, covering engine codes R9M402 and R9M414. Confirm the engine code on your V5C before ordering.

Which vehicles does 0445110414 fit?

This family has 6 verified fitments across Renault and Vauxhall — the full registry-verified list is on this page.

My injector is etched with a different number — is it the same part?

0445110414 cross-references 0986435211, 95518000 and 166105302R. If your etched number appears in this family's reference list it is a verified equivalent; if not, send us a photo of the etching and we will confirm before you order.

Do I need to code the replacement injector to the ECU?

Yes on common-rail diesels. Every injector ships with an individual calibration code that must be written to the ECU after fitting, following the manufacturer procedure — without it the engine runs on default trims and can log cylinder-balance faults.

How is each injector tested before despatch?

Every unit is bench-calibrated against the manufacturer specification — delivery, back-leak and response verified — and despatched with a 12-month parts warranty and its calibration data retained on file.

Common failure symptoms

On the Renault/Vauxhall 1.6 dCi R9M platform, a failing Bosch 0445110414 injector typically presents as: hard starting or extended cranking; rough or uneven idle; loss of power under load; excess smoke from the exhaust; cylinder misfire or contribution fault codes.

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.

When two or more symptoms appear together, suspect the injector before peripherals (EGR, glow plugs, turbo). A live-data leak-off test on each cylinder is the fastest route to the failed unit.

What Causes These Injectors To Fail

The documented failure modes on this platform are: injector back-leak beyond specification; nozzle wear degrading the spray pattern; combustion gas leaks past the injector seat washer.

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

How Workshops Diagnose 0445110414 Faults

Run a comparative leak-off (back-leak) test across all injectors before condemning a single unit. Compare requested vs actual rail pressure in live data at idle and under load. Inspect injector connectors and wiring before replacing hardware.

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.

How Every Unit Is Tested Before Despatch

Each remanufactured 0445110414 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.

OE & Cross-References

0445110414 supersedes or cross-references 3 further OE numbers, including 0986435211, 95518000 and 166105302R. 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.
