Genuine 059 907 807AN Nitrogen Oxide NOx Sensor - 059 907

The Genuine 059 907 807AN is a factory OEM nitrogen oxide (NOx) sensor designed for Volkswagen, Audi, and Porsche diesel vehicles equipped with selective catalytic reduction (SCR) emission control systems. This precision sensor monitors nitrogen oxide concentration levels in the exhaust stream and transmits real-time data to the engine control module to optimize emissions performance and fuel efficiency.

Key Features:

• Genuine OEM quality sensor manufactured to Volkswagen Group specifications
• Precisely measures NOx levels in exhaust gases for emission system control
• High-accuracy sensing element with fast response time
• Durable metal construction for long service life in harsh exhaust environments
• Integrated wiring harness connector for direct plug-and-play installation
• Critical component for maintaining proper diesel emission system function

This NOx sensor plays a vital role in reducing harmful nitrogen oxide emissions by providing accurate feedback to the diesel exhaust treatment system. When functioning properly, it helps ensure optimal performance of the SCR catalyst and urea injection system. Failed or malfunctioning NOx sensors can trigger check engine lights, reduce fuel economy, and cause the vehicle to enter limp mode.
