Bosch 0445110468 2.0 TDI (EA288) Common Rail Injector (VW/Audi/Seat/Skoda)

AI Technical Summary

Bosch solenoid common-rail injector for the VW Group EA288 2.0 TDI engine, fitted across VW Golf/Passat, Audi A3/A4/Q5, Seat Leon and Skoda Octavia/Superb. Bosch alternate 0986435258; VW/Audi OE 04L130277. Main failure causes are poor fuel filtration, fuel contamination and back-leakage wear; replacements are coded to the ECU via the injector correction (IQA) 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 / poor spray.

Common Symptoms

Rough idle / vibrationhigh

A leaking or out-of-range EA288 injector unbalances cylinder fuelling, giving a rough idle.

Hard startinghigh

Excess back-leakage drops cranking rail pressure on the 2.0 TDI.

Loss of power / limp modehigh

Out-of-range injector delivery or rail-pressure deviation cuts power.

Black smokemedium

Poor atomisation from a worn or coked nozzle over-fuels the cylinder.

Engine management lightmedium

Cylinder-specific injector, rail-pressure or fuel-metering fault codes.

Increased fuel consumptionmedium

Over-fuelling and leak-off waste fuel.

Workshop & Fitting Notes

InstallationCode the new/reman injector's correction (IQA) value to the correct cylinder with VCDS/ODIS before road test - the EA288 ECU needs the per-injector trim.
InstallationAlways renew the combustion seal and clamp hardware and torque to spec; reused seals and over-torque are common comebacks.
MisdiagnosisRead live injector correction / back-leakage data to find the weak cylinder before removal instead of replacing all four blind.
WarningAddress contamination (filter, water, debris) first - water-in-fuel corrosion will destroy new injectors quickly.
TestingBench-test on a Bosch-capable CR tester across delivery and back-leakage points; verify spray pattern and cylinder balance.

Frequently Asked Questions

What is Bosch injector 0445110468?+

A Bosch solenoid common-rail diesel injector for the VW Group EA288 2.0 TDI engine. Bosch alternate number 0986435258; VW/Audi OE 04L130277.

Which vehicles use 0445110468?+

VW Golf 7, Passat B8, Tiguan, Sharan, Caddy; Audi A3/A4/A5/Q3/Q5; Seat Leon/Alhambra; and Skoda Octavia/Superb/Kodiaq 2.0 TDI (EA288).

Is it solenoid or piezo?+

It is a Bosch solenoid common-rail injector.

What is the Bosch alternate number?+

0986435258 is the Bosch alternate; 0445110469 is a related alternate, and VW/Audi OE is 04L130277 / 04L130277AC.

Does the EA288 injector need coding?+

Yes - write the injector correction (IQA) value to the correct cylinder with VCDS/ODIS when fitting, or the ECU cannot trim that injector correctly.

What are the symptoms of a failing 0445110468?+

Rough idle, vibration, hard starting, black smoke, power loss or limp mode, an EML and higher fuel use.

Why does my 2.0 TDI vibrate at idle?+

A worn or leaking injector unbalances fuelling. Read live correction values and bench-test to confirm the faulty cylinder.

What causes these injectors to fail?+

Poor fuel filtration, fuel contamination (including water) and back-leakage wear - fix the cause, not just the injector.

Should I replace one or all four?+

Diagnose each with live correction data and a bench test; on high-mileage EA288 engines failures often cluster, so check all four.

Do I need to renew the seals?+

Yes - renew the combustion seal and clamp hardware; reused seals cause blow-by and carbon build-up.

Does a remanufactured 0445110468 perform like new?+

A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan to meet original delivery and back-leakage specs, then coded on fitment.
