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

Based on VW Group (VAG) OEM EPC data and verified aftermarket catalog listings, part number 04L907807DG (SNS0752C family) is used in Volkswagen Group Euro 6 diesel SCR (AdBlue) systems, mainly on 2.0 TDI EA288 engines (MQB platform vehicles).

Confirmed applications include:

• Volkswagen Golf VII / Golf Sportsvan 2.0 TDI Euro 6 SCR
• Volkswagen Passat B8 2.0 TDI Euro 6 SCR
• Volkswagen T-Roc 2.0 TDI SCR diesel variants
• Audi A3 (8V) 2.0 TDI Euro 6 SCR
• Audi Q2 2.0 TDI SCR
• Skoda Octavia III / IV 2.0 TDI SCR
• Skoda Superb III 2.0 TDI SCR
• Seat Leon / Ateca 2.0 TDI SCR
• Cupra Ateca / Leon 2.0 TDI SCR

Fitment is strictly based on OE number matching:
04L907807DG / Bosch 0281007333 / 0281007334 / SNS0752C

Verified Cross-Reference (Important)

• OEM listings confirm 04L907807DG is a VW Group SCR NOx sensor used across Audi / VW / Skoda / Seat EA288 diesel platforms
• Aftermarket EPC data confirms equivalence across VW / Audi / Skoda / Seat / Cupra with Bosch references 0281007333 and 0281007334
• Sensor belongs to SNS0752C SCR NOx family used on Euro 6 MQB diesel vehicles (inlet/outlet position depending on exhaust layout)

📌 Key point:
This is a VW EA288 SCR NOx sensor (SNS0752C family) and is ECU-coded—DG, FP, DG variants are not interchangeable without matching calibration/software.

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 injects AdBlue (urea solution) into the exhaust stream to reduce NOx emissions and meet Euro 6 standards.

The SNS0752C module 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 signal or communication fault
• P2200 / P229F / U029E type codes (VW-specific variants possible)
• Reduced engine power (limp mode)
• Incorrect AdBlue consumption or SCR efficiency faults

OE / Part Numbers

• 04L907807DG
• Bosch 0281007333 / 0281007334
• SNS0752C
• VW Group EA288 SCR NOx sensor family
• Related variants: 04L907807FP (similar platform but not always interchangeable)

FAQ

Is this sensor interchangeable with other VW NOx sensors?

No. VW uses ECU-coded SCR sensors. Even if connectors are identical, DG / FP / CJ / AP variants are calibration-specific.

Why is it used across VW, Audi, Skoda, Seat, and Cupra?

Because all share the same EA288 2.0 TDI Euro 6 SCR diesel platform (MQB architecture).

Is this inlet or outlet sensor?

It depends on vehicle layout. This sensor is used in SCR inlet or outlet positions depending on exhaust configuration.
