High-Quality 0445117033 Diesel Injector Compatible with Bosch for VW Audi Porsche 3.0 TDI – Reliable Performance by Rsolid Engine Parts
If you own a 3.0L TDI vehicle from Volkswagen, Audi, or Porsche, you know that precise fuel injection is the heart of engine performance and fuel economy. The 0445117033 diesel injector (compatible with Bosch original equipment) is a critical component that ensures optimal combustion, reduced emissions, and smooth power delivery. At Rsolid Engine Parts, we provide premium-grade injectors that meet or exceed OEM standards, helping you restore your diesel engine's factory performance.
1. Structural Features & Advantages
The 0445117033 injector is designed as a high-precision solenoid or piezo common rail injector (OE-style compatible with Bosch). Its key structural highlights include:
Multi-hole nozzle design – Delivers an atomized fuel spray pattern for complete combustion, reducing soot and improving throttle response.
Hardened internal valve train – Resists wear from high injection pressures (up to 2000 bar), ensuring long service life even under heavy loads.
Precision-ground solenoid or piezo stack – Enables ultra-fast injection timing control, reducing engine noise and cold-start issues.
Corrosion-resistant materials – Built to withstand aggressive diesel fuel additives and moisture, preventing common failure modes like stuck needles.
Advantages for your 3.0 TDI engine:
Restores lost horsepower and torque
Lowers fuel consumption by up to 5–10% when replacing worn injectors
Reduces diesel knock and white smoke at startup
Plug-and-play compatibility – direct fit for Bosch systems without ECU recalibration (though coding is recommended)
2. Compatible Vehicle Models
The 0445117033 injector is widely used in 3.0-liter TDI engines from the Volkswagen Group. It fits the following vehicles (check your VIN and engine code, e.g., CRCA, CRTD, CVUA, CVUB, DEWA, etc.):
| Brand | Model Series | Years (approx.) |
|---|
| Audi | A4 (B8/B9), A5, A6 (C7/C8), A7, A8, Q5, Q7 | 2009–2019 |
| Volkswagen | Touareg 3.0 TDI | 2011–2018 |
| Porsche | Cayenne Diesel, Panamera Diesel | 2013–2017 |
Always confirm with your original injector part number (0445117033) and engine code before purchase.
3. Common Failures, Maintenance & Installation Tips
Common signs of a failing 0445117033 injector:
Rough idle or misfire on one cylinder
Excessive black or white smoke from exhaust
Increased oil dilution (fuel in oil)
Hard starting, especially when cold
Failed injector balance test via diagnostic scanner
Maintenance recommendations:
Replace diesel fuel filters every 20,000–30,000 km to prevent debris from damaging the injector nozzle.
Use high-quality diesel fuel and additive cleaners every 10,000 km.
Have injector return flow and balancing tested during major service intervals (every 80,000 km).
Installation essentials:
Always replace copper sealing washers and O-rings – Reusing old seals leads to combustion gas leakage.
Clean the injector bore – Carbon buildup can cause misalignment.
Apply anti-seize compound to the threads (sparingly).
Torque to manufacturer spec – Typically 25–30 Nm + a specified angle (consult workshop manual).
Perform injector coding/adaptation using VCDS, ODIS, or PIWIS – Each new injector has an IQA code that must be programmed into the ECU.
