038906018A Audi Motor Kontrol Ünitesi – Orijinal Kullanılmış & Test Edilmiş

Açıklama

038906018A parça numarasını taşıyan bu, VAG Grubu'nun 1.9 TDI motor ailesi arasında takılı olan orijinal fabrika dizel motor denetleyicisidir. Audi, Volkswagen, SEAT and Škoda vehicles. This specific calibration governs injection timing, quantity and duration, EGR management, turbocharger control and cold-start glow sequences for the relevant 1.9 TDI engine code, making it the operational heart of the diesel management system on the applicable vehicle.

The 038 prefix identifies this as an engine management unit from the 1.9 TDI series across the VAG product range. The ECU processes inputs from the high-pressure fuel system sensors, intake air mass meter, EGR position sensor and the crankshaft and camshaft encoders to produce injection commands that balance power delivery with fuel efficiency — the defining characteristic of the 1.9 TDI’s long-standing reputation for economy and longevity.

When this ECU type is failing on a 1.9 TDI-equipped Audi, typical symptoms include the engine losing power progressively over time without an obvious hardware fault, torque cutbacks appearing at consistent rev ranges confirmed by live data showing quantity reduction, or stored diagnostic codes for fuel mass deviation or rail pressure irregularity that cannot be resolved by replacing the injectors or pressure regulator valve.

This is a genuine used OEM part removed from a 1.9 TDI VAG application and tested for basic operation before sale. All used VAG diesel ECUs require coding and immobiliser adaptation using VCDS or equivalent diagnostic tooling at the time of installation. Verify the part number matches your existing unit before purchasing.
