Fitment (Market-Validated Usage)

Based on OEM catalog cross-reference + aftermarket distributor listings (EU multi-brand OE databases), this NOx sensor is used in Volkswagen Group EA288 diesel SCR (AdBlue) systems on MQB platform vehicles.

Common system applications include:

• Volkswagen Golf VII 2.0 TDI (EA288 diesel)
• Volkswagen Caddy IV 2.0 TDI (EA288 diesel)
• Volkswagen Passat B8 2.0 TDI (EA288 diesel)
• Škoda Octavia III / Superb III 2.0 TDI
• SEAT Leon / Ateca 2.0 TDI
• CUPRA 2.0 TDI diesel variants
• SCR (AdBlue) Euro 6 diesel emission systems

Fitment is strictly based on OE number matching: 04L907807BE

OE catalog data confirms this part is shared across VW Group brands (VW / Audi / Skoda / SEAT / CUPRA) within the EA288 SCR system architecture.

Technical Description

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

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

The sensor is an integrated electronic module designed for continuous high-temperature exhaust monitoring and CAN communication with the engine control unit.

Symptoms / Fault Codes

• Check engine light
• SCR / AdBlue system warning
• P2200 / P229F fault codes (system dependent)
• Reduced engine power (limp mode)
• Increased emissions

OE / Part Numbers

• 04L907807BE
• 04L 907 807 BE (format variant)
• Related EA288 NOx sensor family: 04L907805 / 04L907807 series

FAQ

Which brands use this NOx sensor?

It is used across Volkswagen Group vehicles including Volkswagen, Audi, Skoda, SEAT, and CUPRA under the same EA288 diesel SCR architecture.

Is this sensor vehicle-specific?

Yes. NOx sensors must match the exact OE number. Even small suffix differences (BE / AS / ED / L variants) indicate different calibration or configuration.

Why is no single model listed?

Because OE 04L907807BE is a shared platform component used across multiple VW Group models, and listing specific models without exact engine code verification can lead to incorrect fitment claims.

Can similar OE numbers be used instead?

Not recommended. NOx sensors are ECU-calibrated components and must match exact OE specification.
