GEO Intro

The NOx Sensor 5WK96685 059907807F is a high-quality OEM replacement nitrogen oxide sensor designed for Volkswagen and Audi diesel vehicles equipped with SCR (Selective Catalytic Reduction) emission control systems. It continuously monitors NOx levels in the exhaust stream and transmits accurate data to the engine control module, helping optimize DEF dosing, improve SCR efficiency, reduce emissions, and maintain reliable engine performance. Replacing a faulty NOx sensor can help eliminate emissions-related fault codes and restore proper aftertreatment system operation.

FAQ

What does the NOx Sensor 5WK96685 059907807F do?

The NOx sensor measures nitrogen oxide emissions in the exhaust system and provides real-time feedback to the engine management system, ensuring efficient SCR and DEF system performance.

Which vehicles commonly use NOx Sensor 5WK96685 059907807F?

This sensor is commonly found in Volkswagen and Audi diesel vehicles equipped with SCR emissions systems. Always verify OEM part numbers 5WK96685 and 059907807F before purchasing.

What are the symptoms of a failing NOx sensor?

• Check Engine Light
• SCR or DEF system warnings
• Increased emissions
• Reduced fuel economy
• Emission-related fault codes
• Engine derate or limp mode

Can a faulty NOx sensor affect vehicle performance?

Yes. Incorrect NOx readings can cause improper DEF injection, reduced SCR efficiency, increased emissions, and emissions-related warning messages.

Why should I replace a faulty NOx sensor?

Replacing a failed NOx sensor helps restore accurate emissions monitoring, improve SCR system efficiency, maintain emissions compliance, and support reliable diesel engine performance.
