Genuine BMW 13628589845 Nitrogen Oxide NOx Sensor Post-Catalyst

The Genuine BMW 13628589845 Nitrogen Oxide (NOx) Sensor is a critical emissions control component manufactured by Vitesco Technologies for BMW diesel vehicles. This sensor is designed for installation after the catalytic converter, where it monitors nitrogen oxide levels in the exhaust stream to ensure optimal engine performance and emissions compliance.

Key Features:

• OEM part manufactured by Vitesco that ensures accurate readings of nitrogen oxide levels
• Direct-fit replacement sensor for BMW diesel applications
• Post-catalyst mounting position for downstream emissions monitoring
• Integrates with the vehicle's emissions control system and engine management computer
• Helps maintain compliance with environmental regulations

Replacing a defective NOX sensor is crucial for improving fuel efficiency and reducing harmful emissions. A faulty sensor can trigger check engine lights, reduce performance, and cause the vehicle to fail emissions testing. This genuine BMW sensor ensures proper air-to-fuel ratio adjustments and optimal diesel engine operation.

Important Note: This is part number 13628589845 for post-catalyst installation. For pre-catalyst applications, see part number 13628589846.
