Manufactured using high-quality automotive-grade components with heat-resistant electrical connections and durable sealing materials, the repair kit is engineered to withstand exposure to diesel emissions fluid, moisture, vibration and repeated thermal cycling. Designed for direct OE-style installation, it integrates seamlessly with the vehicle's SCR and AdBlue® system, restoring reliable operation and helping maintain emissions compliance.  

What This Product Does:

• Restores operation of the diesel emissions fluid (DEF/AdBlue®) pre-heater.
• Helps prevent DEF/AdBlue® from freezing in cold temperatures.
• Maintains the correct operating temperature of the emissions fluid.
• Supports efficient Selective Catalytic Reduction (SCR) system performance.
• Helps reduce harmful NOx emissions.
• Assists compliance with manufacturer emissions standards.
• Restores factory emissions system functionality.
• Forms an essential part of the vehicle's 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.
• Reduced emissions system efficiency.
• Difficulty operating the emissions system in cold weather.
• Vehicle entering reduced power or limp-home mode.
• Increased NOx emissions.
• Failed emissions or MOT inspection.
• DEF/AdBlue® system malfunction warnings.
• Restricted engine restart countdown on some vehicles.

Why Replacement Matters:

• The diesel emissions fluid pre-heater operates in demanding conditions and is essential for maintaining the correct temperature of the DEF/AdBlue® solution, particularly during cold weather. Over time, heating elements, electrical connections or sealing components can deteriorate due to thermal cycling, moisture and vibration.
• A faulty pre-heater can prevent the SCR system from operating correctly, resulting in increased emissions, warning lights and potential restrictions on vehicle performance or restarting. In many cases, continued operation with a defective DEF/AdBlue® heating system may eventually prevent the vehicle from meeting emissions regulations or operating normally.
• Replacing worn or faulty components with the OE Match Diesel Emissions Fluid Pre-Heater Repair Kit restores reliable DEF/AdBlue® heating and SCR system operation. Manufactured to OE standards using premium-quality materials, this repair kit provides factory-style fitment, dependable performance and long-lasting durability, helping maintain emissions compliance, engine efficiency and the reliability expected from your Porsche.
