Engine Intelligence

VW / Audi / Škoda / SEAT 2.0 TDI (EA288 Gen2 — A4, A3, Golf, Passat, Tiguan) DFGA

Common symptoms

  • Unstable idle or shaking at idle
  • Loss of power, poor acceleration or limp mode
  • Diesel knock or metallic rattling, especially cold or under load
  • White or black smoke
  • Hard starting; fuel smell or a rising oil level in advanced cases

Documented failure modes

  • Injector delivery drift showing as deviation values out of range
  • Injector electrical faults logging cylinder circuit codes
  • Leaking or stuck-open injector diluting the engine oil with diesel

Diagnostic guidance

  • Log injector correction values in diagnostic software — a large outlier identifies the weak unit
  • Check the engine oil for diesel dilution on suspected leaking injectors
  • EGR, DPF and fuel-pressure faults overlap with injector symptoms on the EA288 — confirm with leak-back and live rail-pressure data
  • Injector coding is required after fitting — follow the manufacturer procedure

Fault codes linked to this engine's injectors

Fitment note: EA288 Gen2 2.0 TDI spans many engine codes and outputs, and the 1.6 TDI side of the platform uses different references — always match the number etched on the injector body.

Why this injector?

  • Fits the DFGA engine code used in the Audi A3 (8V) and related diesel variants.
  • Bosch diesel injector — flow-tested and calibrated on common-rail equipment before despatch.
  • Commonly specified when investigating rough idle, injector knock, smoke or poor fuel economy on DFGA engines.
  • 12-month warranty, free UK delivery and no core exchange required.

Bosch 04L130277AC 2.0 TDI Common Rail Injector (VW Golf/Passat, Audi A3, Seat Leon, Skoda Octavia EA288)

AI Technical Summary

Bosch 04L130277AC (Bosch 0445110611/0445110612) CRI2.20 piezo common-rail injector for the VW Group 2.0 TDI EA288 (DFGC/DEUC/DBGC) across VW Golf VII/Passat B8/Tiguan, Audi A3/Q3, Seat Leon and Skoda Octavia/Superb. IMA/IQA correction coding required. Remanufactured, calibrated, 12-month warranty. Key symptoms: Rough idle / vibration; Hard starting; Loss of power / limp mode; Black smoke. Common failure modes: Internal wear / high back-leakage; Nozzle coking / poor spray pattern; Water-in-fuel corrosion.

Common Symptoms
Rough idle / vibrationhigh

A leaking or out-of-calibration injector unbalances cylinder fuelling, felt as a shake at idle.

Hard startinghigh

Excess back-leakage bleeds rail/line pressure during cranking, causing long or failed starts.

Loss of power / limp modehigh

Out-of-range delivery or pressure deviation triggers a torque cut and limp home.

Black smokemedium

Poor atomisation or a dribbling nozzle over-fuels the cylinder.

Engine management lightmedium

Cylinder-specific injector, balance or fuel-metering fault codes are logged.

Workshop & Fitting Notes
  • InstallationCode the injector IMA/IQA correction value to the correct cylinder with VCDS/ODIS on fitment before road test.
  • InstallationRenew the copper combustion washer and leak-off seals; torque the clamp/nut to manufacturer spec.
  • MisdiagnosisRead live back-leakage and per-cylinder contribution data to confirm the weak cylinder before removal.
  • TestingBench-test across delivery and back-leakage points and verify spray pattern before refit.
  • WarningConfirm fitment by OE number and engine code before ordering; injector sub-variants are not always interchangeable.
Frequently Asked Questions
What is injector 04L130277AC?+

04L130277AC is a Bosch common rail piezo injector (cri2.20) diesel injector for the VW Group 2.0 TDI EA288 (DFGC/DEUC/DBGC). It is supplied remanufactured, bench-tested and calibrated to OEM specification.

Which vehicles use 04L130277AC?+

It is fitted to the VW Group 2.0 TDI EA288 (DFGC/DEUC/DBGC) — including Volkswagen Golf (Mk7) 2.0 TDI (EA288, DFGC/DEUC); Volkswagen Passat (B8) 2.0 TDI (EA288, DFGC/DEUC); Volkswagen Tiguan (AD1) 2.0 TDI (EA288, DFGC/DBGC); Audi A3 (8V) 2.0 TDI (EA288). Confirm fitment by OE number and engine code.

What type of injector is 04L130277AC?+

It is a Bosch Common Rail Piezo Injector (CRI2.20). Always confirm the OEM markings on the injector body before fitting.

Does 04L130277AC need coding when fitted?+

Yes — the injector IMA/IQA correction value must be written to the correct cylinder with VCDS/ODIS on fitment.

What are the symptoms of a failing 04L130277AC?+

Common signs are rough idle and vibration, hard starting, power loss or limp mode, black smoke and an engine-management light.

What causes these injectors to fail?+

Most failures come from poor fuel filtration, contamination and water in the fuel leading to wear, high back-leakage and nozzle coking. Fix the cause before fitting replacements.

Is a remanufactured 04L130277AC as good as new?+

A properly remanufactured injector is stripped, fitted with new wear parts, reassembled and recalibrated on a common-rail test bench to OEM tolerances, then supplied with a warranty.

Should I replace one injector or the full set?+

Replace the confirmed faulty injector first. On high-mileage engines fitting a matched set reduces the chance of a repeat fault, but it is not mandatory if the others test within spec.

Do you bench-test the injector before dispatch?+

Yes. Every unit is tested for delivery, back-leakage and spray pattern on a calibrated common-rail tester before it leaves us.

Is delivery and warranty included?+

Yes — the price includes free UK delivery and a 12-month warranty.

Does 04L130277AC need IMA/IQA coding?+

Yes — write the injector IMA/IQA correction value to the correct cylinder with VCDS/ODIS on fitment, or the EA288 2.0 TDI may run rough and log balance faults.

Is this the 1.6 TDI or 2.0 TDI EA288 injector?+

04L130277AC is the 2.0 TDI EA288 injector (DFGC/DEUC/DBGC). It is not interchangeable with the 1.6 TDI EA288 injector — confirm the OE suffix and engine code before ordering.
