Ensure your diesel vehicle meets emissions standards and runs reliably with this premium NOx Sensor — supplied by D2P Autoparts and designed to replace worn or failed exhaust-gas sensors in Citroën, Peugeot, DS, Opel/Vauxhall and similar diesel models. This NOx Sensor accurately measures nitrogen oxides (NOx) levels in the exhaust, allowing the engine’s ECU and SCR/after-treatment system to adjust fuel-air mixture and AdBlue/DEF dosing for cleaner emissions and optimal engine performance. Whether you’re dealing with emission-related warning lights, failed MOT/inspection, or poor engine running, this high-quality sensor helps restore emissions compliance, improve fuel efficiency, and keep your diesel running smoothly and cleanly.

Key Benefits — Why Choose This NOx Sensor

• Essential for legal emissions compliance & clean exhaust output — The NOx Sensor monitors NOx levels and helps the exhaust after-treatment system (e.g. SCR/DEF) reduce harmful emissions, ensuring your vehicle stays within regulatory limits.

• Helps restore engine performance and fuel economy — A working NOx Sensor provides accurate data to the ECU so combustion and exhaust treatment are optimised; a faulty sensor may cause poor fuel-economy, reduced power or inefficient fuel burn.

• Prevents “limp-mode”, error codes and DEF/SCR system faults — Faulty NOx readings often trigger fault codes, reduced power output, or DEF-system warnings; replacing the sensor clears these issues and restores normal function.

• Extends longevity of emissions and exhaust system components — Accurate NOx feedback helps ensure correct exhaust-gas treatment, protecting catalytic converters, DPF/SCR components and avoiding damage from incorrect dosing or overloading.

• High-quality aftermarket replacement — cost-effective vs dealer parts — Offers OEM-compatible performance at better value, ideal for maintenance or restoring full emissions compliance without high dealer-level pricing.

• Suitable for a wide range of diesel vehicles (Citroën, Peugeot, DS, Opel/Vauxhall) — If your vehicle’s original NOx sensor has failed, this part serves as a direct replacement, restoring proper emissions-control function.

❓ Frequently Asked Questions (FAQ)

Q: What does a NOx sensor do, and why is it needed?
A: The NOx Sensor monitors the concentration of nitrogen oxides (NOx) in the exhaust gases of a diesel engine. It sends that information to the vehicle’s exhaust after-treatment system (e.g. SCR/DEF), which then adjusts fuel-air mixture, DEF dosing or catalytic converter operation to reduce NOx emissions and meet legal emission standards.

Q: What are common symptoms of a failing NOx sensor?
A: Common signs include: emission-system warning lights or “check engine” light; reduced engine power or limp-mode; poor fuel economy; frequent AdBlue/DEF usage or DEF-system warnings; rough running or difficult starting; failed emissions tests.

Q: What causes NOx sensors to fail?
A: Main causes are extreme heat and thermal stress (from hot exhaust gases) over time; soot, carbon or oil contamination in exhaust; water or condensation entering the exhaust; exhaust leaks or harsh vibrations; damaged wiring or connectors.

Q: Will replacing the NOx sensor fix emission / performance problems?
A: If the problems are caused by a faulty NOx sensor — such as incorrect NOx readings, mis-dosing of DEF, poor combustion or emission-control malfunctions — then replacing the sensor often restores proper emissions control and engine performance. However, if there are additional issues (e.g. damaged SCR or DPF, wiring problems, exhaust leaks), those may also need attention.

Q: Is this sensor compatible with my Citroën / Peugeot / DS / Opel / Vauxhall diesel?
A: This NOx sensor is designed to match part number 9821120980 (98 211 209 80). Before ordering, always check that your vehicle’s engine type, exhaust system (SCR, AdBlue/DEF) and original sensor part number correspond — to ensure correct fitment and operation.

Q: Why buy this NOx sensor from D2P Autoparts?
A: Because we provide high-quality, OEM-equivalent sensors that offer reliable emission-control performance, stable sensor readings, and long-term durability — all at a competitive price compared to main dealer parts, making it a cost-effective, dependable replacement.
