Fitment (Market-Verified Usage)

Based on OEM cross-reference listings and aftermarket catalog data, 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 Passat B8 2.0 TDI (EA288 diesel)
• Volkswagen Tiguan 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: 04L907807DL

OE catalog data confirms this part is widely shared across VW Group brands within EA288 SCR 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 injection to reduce NOx emissions and maintain Euro 6 compliance.

Designed for high-temperature exhaust environments with integrated electronics and continuous CAN communication to 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

• 04L907807DL
• 04L 907 807 DL (format variant)
• Cross-referenced within EA288 NOx sensor family (04L907805 / 04L907807 series)

FAQ

Is this sensor vehicle-specific?

Yes. NOx sensors must match the exact OE number. Even small suffix differences (DL / AS / ED variants) can indicate different calibration, cable length, or sensor position.

Why are multiple VW Group brands listed?

Because Volkswagen Group (VW / Audi / Škoda / SEAT / CUPRA) shares the same EA288 diesel SCR platform architecture.

Can similar OE numbers be used instead?

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