Introduction

Welcome to AutoMan Spare Parts, your trusted global hub for OEM automotive electronics. We supply a huge range of genuine NOx sensors and control modules, ensuring that your vehicle runs cleaner, more efficiently, and in full compliance with emission standards.

Today, we focus on one of the most in-demand emission control components — the NOx Sensor Control Module 5WK97103A / A2C97451500-01 OEM — a crucial part of the exhaust after-treatment system in modern diesel vehicles.

What is the NOx Sensor Control Module 5WK97103A / A2C97451500-01?

The 5WK97103A / A2C97451500-01 NOx Sensor Control Module is a genuine OEM part used in advanced diesel engines to monitor and regulate nitrogen oxide (NOx) emissions. It communicates with the vehicle’s Engine Control Unit (ECU) to optimize air-fuel ratios and reduce harmful gases.

This module integrates a high-precision sensor probe and a smart control unit, designed to withstand high exhaust temperatures and deliver consistent real-time data for emission management.

Key Features

  • OEM Quality Assurance: Manufactured to original equipment standards (OEM-certified).

  • High-Temperature Resistance: Performs accurately under extreme exhaust conditions.

  • Fast Response Rate: Provides instant NOx level feedback to ECU for precise fuel adjustments.

  • Enhanced Durability: Designed with corrosion-resistant materials for long service life.

  • Emission Compliance: Meets Euro 5 and Euro 6 regulations for diesel engines.

  • Plug-and-Play Fitment: Direct replacement for 5WK97103A / A2C97451500-01 models — no coding required in most vehicles.
