Bosch 0445110080 – Next‑Level Diesel Common Rail Injector

📌 Part Identity

Part Number: 0445110080 / Bosch OEM 0 445 110 080

Injector Type: CRI2.1 Common Rail Diesel Injector

Spray Class: DLLA160P1063 (High‑precision nozzle)

Cross‑Reference: Includes 0445110131, 0986435084, and others used on similar platforms

This injector belongs to the globally compatible Bosch 110 series, widely deployed across diesel platforms for its efficient combustion atomization and robust build quality.

📏 Performance Insight – CRI2.1 nozzles like this are optimized for multiple injections per cycle, maximizing energy output and effectively reducing particulate formation.

Originally engineered for European‑spec diesel engines, this injector frequently appears as standard or interchangeable equipment on BMW 2.0 L and 3.0 L diesel platforms, especially those equipped with M 47 and M 57 diesel engines. These engines rely on precise injector timing to control combustion across varied operating states - from cold starts to highway cruising.

🚗 Typical service applications include:

BMW 320d / 330d series (e.g., E46, E60 variants)

Vehicles using the 0445110131 part family, where 0445110080 often serves as a functional equivalent
Usage across these vehicles demands tight control over injection timing to maintain emission compliance and performance balance.

At the heart of any common rail system lies the principle of decoupled pressure generation and fuel metering - meaning high‑pressure fuel is stored in a common rail and released on demand as directed by the ECU.

🔹 Precision Timing: The Bosch 0445110080 executes multiple micro‑injections per cycle, allowing first small "pilot" fuel charges just before the main event - a strategy that both lowers NVH (noise, vibration, harshness) and sharpens torque response.
🔹 Emission Control: By dividing fuel delivery into optimized pulses, this injector supports cleaner burns with fewer unburned hydrocarbons.
🔹 Fuel Economy: Better spray atomization increases surface area contact with air, leading to more complete combustion and improved MPG figures.

These characteristics make the 0445110080 ideal for diesel enthusiasts, professional mechanics, and OEM replacements alike, particularly where efficiency and reliability are non‑negotiable.

✔ Diagnostic Reset: After installation, performing a fuel system adaptation via OEM‑grade diagnostic tools ensures the ECU correctly harmonizes with the new injector's performance curve.
✔ Fuel Quality: High‑pressure CRI injectors are sensitive to contaminants; always use precision filtration and quality diesel fuel.
✔ Matched Sets: For 6‑cylinder engines, replacing injectors in matched sets helps preserve balance and smooth combustion across cylinders.
