28654963 — Technical Research
Delphi solenoid common-rail injector for the VW Group 2.0 TDI EA288 engine, widely used on the VW Crafter, Transporter T6, Caravelle/Multivan and the MAN TGE. VAG OE 04L130277BG/04L130277AP/04L130277BB/04L130277BF; the Bosch counterpart is 0445110470. Replacements are coded to the ECU with the injector IMA correction value. 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 triggers derate.
Poor atomisation over-fuels the cylinder.
Cylinder-specific injector or fuel-metering fault codes.
- InstallationCode the injector IMA correction value to the correct cylinder with VCDS/ODIS before road test.
- InstallationRenew the combustion seal and clamp hardware; torque to spec.
- MisdiagnosisHigh-mileage Crafter/TGE vans are a common application - read live back-leakage data to find the weak cylinder before removal.
- WarningFix contamination (filter/water/debris) first; EA288 injectors are sensitive to fuel quality.
- TestingBench-test across delivery and back-leakage points; verify spray pattern before refit.
What is Delphi injector 28654963?+
A Delphi solenoid common-rail diesel injector for the VW Group 2.0 TDI EA288 engine, common on the VW Crafter, Transporter T6 and MAN TGE. VAG OE 04L130277BG and related; Bosch counterpart 0445110470.
Which vehicles use 28654963?+
VW Crafter, Transporter T6/Caravelle/Multivan, MAN TGE and Audi/Skoda 2.0 TDI EA288 applications.
Is it solenoid or piezo?+
It is a Delphi solenoid common-rail injector.
Does 28654963 need coding?+
Yes - code the injector IMA correction value to the correct cylinder with VCDS/ODIS when fitting.
What are the OE part numbers?+
VAG 04L130277BG, 04L130277AP, 04L130277BB and 04L130277BF reference Delphi 28654963; the Bosch alternate is 0445110470.
How is 28654963 different from 28565336?+
28654963 is the 2.0 TDI injector (Crafter/TGE); 28565336 is primarily the 1.6 TDI unit. Confirm the OE suffix and engine code before fitting.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my Crafter 2.0 TDI run rough?+
A worn or leaking injector unbalances fuelling; read live correction 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 28654963 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Delphi plan, then IMA-coded on fitment.
