Diesel Exhaust Fluid Injector Valve. Porsche 958 Cayenne 3.0L Diesel 2012-17  ❭  95811141335

Diesel Exhaust Fluid Injector Valve.
The Genuine Porsche Diesel Exhaust Fluid (DEF/AdBlue) Injector Valve is an original equipment emissions control component designed to precisely inject Diesel Exhaust Fluid (DEF/AdBlue) into the exhaust system of compatible Porsche diesel models. Manufactured to Porsche's exact specifications for fit, performance and durability, this injector valve plays a critical role in the Selective Catalytic Reduction (SCR) system by delivering the correct amount of DEF to reduce harmful nitrogen oxide (NOx) emissions.  

Fits:

Manufactured from premium high-temperature-resistant materials with precision-engineered internal valve components, the injector is designed to operate reliably under extreme exhaust temperatures, pressure fluctuations and harsh operating conditions. Its accurate spray pattern ensures efficient mixing of DEF within the exhaust gases, allowing the SCR catalyst to convert harmful NOx emissions into harmless nitrogen and water vapour. Designed as a direct replacement for the original component, it integrates seamlessly with the vehicle's engine management and emissions control systems.  

What This Product Does:

• Precisely injects Diesel Exhaust Fluid (DEF/AdBlue) into the exhaust system.
• Supports the operation of the Selective Catalytic Reduction (SCR) system.
• Helps reduce harmful nitrogen oxide (NOx) emissions.
• Ensures efficient DEF atomisation and distribution.
• Supports compliance with vehicle emissions regulations.
• Communicates with the engine management system for accurate dosing.
• Restores factory emissions system performance.
• Forms an essential part of the diesel exhaust after-treatment system.

Symptoms Of Wear Or Failure:

• Illuminated engine management or emissions warning light.
• AdBlue or DEF system warning messages.
• SCR system fault codes.
• Increased NOx emissions.
• Reduced engine performance or limp-home mode.
• Excessive DEF consumption or incorrect dosing.
• Crystallised DEF deposits around the injector.
• Blocked or restricted injector nozzle.
• Failed emissions or MOT inspection.
• Difficulty completing emissions system regeneration or diagnostic procedures.

Why Replacement Matters:

• The DEF injector valve operates in an extremely demanding environment, where it is continually exposed to high exhaust temperatures, vibration and DEF fluid. Over time, mineral deposits, crystallisation, contamination or normal wear can restrict the injector nozzle or prevent accurate dosing.
• A faulty injector valve can reduce the efficiency of the SCR system, causing increased emissions, warning lights and potential restrictions in engine performance. Continued operation with a defective injector may also lead to damage to the SCR catalyst or other emissions control components, resulting in more expensive repairs.
• Replacing a worn or faulty injector valve with a Genuine Porsche component restores accurate DEF dosing and ensures the SCR system operates as intended. Manufactured to Porsche's exact standards, the Genuine Diesel Exhaust Fluid Injector Valve provides precise fitment, dependable performance and long-lasting durability, helping maintain emissions compliance, engine efficiency and the reliability expected from your Porsche.
