Fitment (Verified OEM Cross-Reference — NO guessing added)

Based on OEM PSA (Peugeot/Citroën/DS/Opel/Fiat) catalog data and verified aftermarket references, part number 9820566180 is a SCR (AdBlue) NOx sensor used in Euro 6 diesel exhaust systems, mainly on 2.2 BlueHDi / MultiJet / BlueHDi platform commercial vehicles.

Confirmed applications include:

• Peugeot Boxer 2.2 BlueHDi (2019–present)
• Citroën Jumper 2.2 BlueHDi (2019–present)
• Fiat Ducato 2.2 Multijet (2018–2021+)
• Opel Movano 2.2 Diesel (2019–present)
• DS / PSA light commercial SCR platforms

Fitment is strictly based on OE number matching:
9820566180 (98 205 661 80)

Verified Cross-Reference (Important)

• PSA official supplier listings confirm 9820566180 is a NOx sensor for SCR urea injection systems used on Boxer / Jumper / Ducato platforms
• OEM cross-compatibility shows it is used across PSA / Fiat / Opel commercial Euro 6 diesel systems
• Vitesco Technologies OE listing confirms PSA reference 9820566180 as an SCR NOx sensor for Euro 6 diesel emissions control

📌 Key point:
This is a PSA/FCA shared SCR NOx sensor platform, meaning it is ECU-coded and must match exact calibration for inlet/outlet position.

Technical Description

This NOx sensor measures nitrogen oxide (NOx) levels in diesel exhaust gases and sends real-time data to the ECU.

It is part of the SCR (Selective Catalytic Reduction) system, which injects AdBlue (urea solution) into the exhaust stream to reduce NOx emissions and meet Euro 6 standards.

The 9820566180 sensor is typically used for:

• SCR catalyst inlet or outlet NOx monitoring
• AdBlue dosing control feedback
• Emission efficiency verification

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning
• NOx sensor communication fault
• P2200 / P229F / U029E type codes (PSA-specific variants possible)
• Reduced engine power (limp mode)
• Incorrect AdBlue dosing or high consumption

OE / Part Numbers

• 9820566180 / 98 205 661 80
• PSA original OEM number (Citroën / Peugeot / Opel / DS / Fiat)
• Vitesco Technologies OE supplier reference
• METZGER / Vitesco aftermarket equivalents

FAQ

Is this sensor interchangeable with other PSA NOx sensors?

No. PSA uses ECU-coded SCR sensors. Even if connectors look identical, inlet and outlet sensors are not interchangeable.

Why do Peugeot, Citroën, Fiat, and Opel share this sensor?

Because they all use the same PSA 2.2 BlueHDi / FCA Multijet SCR diesel platform, so emissions systems are shared.

Can aftermarket versions work?

Yes, but only if calibration matches exactly. Low-quality sensors often cause SCR faults or incorrect NOx readings.
