55589458/ 5WK97419/ A2C98406700-01 NOx Sensor for Opel Insignia A / Antara 2.0 CDTi OEM.

Product Description

Genuine Nitrogen Oxides (NOx) Sensor suitable for Opel / Vauxhall 2.0 CDTi diesel engines.
This OEM sensor — part numbers 55589458, 5WK97419, and A2C98406700-01 — monitors NOx levels in the exhaust and communicates with the ECU/SCR system to regulate AdBlue dosing, reduce emissions, and maintain optimal engine performance.

A failed NOx sensor often causes:

AdBlue warnings
“Check Engine” light
Loss of power / limp mode
High fuel consumption
Emission system faults

This original specification sensor restores correct operation and emissions compliance.
