0445110986 — Technical Research
Bosch solenoid common-rail injector for the VW 2.0 TDI EA288 (engine codes CXF/CXH/DNA) fitted to the Transporter/Caravelle/Multivan/California T6. VW OE 04L130277BE (supersession 04L130277BH). Replacement injectors are coded to the ECU with the IMA correction value via VAG ODIS. Failures are driven by poor fuel filtration, contamination and back-leakage wear. Key symptoms: Rough idle / vibration; Hard starting; Loss of power / limp mode; Black smoke. Common failure modes: Internal wear / high back-leakage; Water-in-fuel corrosion; Nozzle coking.

A leaking injector unbalances cylinder fuelling on the 2.0 TDI.
Excess back-leakage drops cranking rail pressure.
Out-of-range delivery or rail-pressure deviation cuts power.
Poor atomisation over-fuels the cylinder.
Cylinder-specific injector or fuel-metering codes.
- InstallationCode the IMA correction value to the correct cylinder with VAG ODIS before road test.
- InstallationRenew the combustion seal and clamp hardware; torque to spec.
- MisdiagnosisRead live back-leakage data to find the weak cylinder before removal.
- WarningFix contamination (filter/water/debris) first; the EA288 is sensitive to fuel quality.
- TestingBench-test across delivery and back-leakage points; verify spray pattern before refit.
What is Bosch injector 0445110986?+
A Bosch solenoid common-rail diesel injector for the VW 2.0 TDI EA288 (CXF/CXH/DNA) engine. VW OE 04L130277BE.
Which vehicles use 0445110986?+
VW Transporter, Caravelle, Multivan and California T6 with the 2.0 TDI (CXF/CXH/DNA) engine, roughly 2015-2019.
Is it solenoid or piezo?+
It is a Bosch solenoid common-rail injector.
Does 0445110986 need coding?+
Yes - code the IMA correction value to the correct cylinder with VAG ODIS when fitting.
What are the OE part numbers?+
VW 04L130277BE references Bosch 0445110986; supersession 04L130277BH.
Does it fit passenger 2.0 TDI cars too?+
This number is the T6 commercial 2.0 TDI EA288 injector; passenger EA288 cars can use different OE suffixes - match the OE number stamped on your injector.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my T6 run rough?+
A worn or leaking injector unbalances fuelling; read live back-leakage data and bench-test the weak cylinder.
What causes these injectors to fail?+
Poor fuel filtration, contamination and back-leakage wear - fix the cause first.
Does a remanufactured 0445110986 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan, then IMA-coded on fitment.
