FITMENT:
Compatible with Mercedes-Benz diesel vans and light commercial vehicles equipped with SCR (AdBlue/DEF) systems, including:

• Mercedes Sprinter W906 / W907 (selected Euro 6 diesel variants)
• Mercedes Vito W447 (2014–present diesel models)
• V-Class W447 / Viano replacements
• Some Renault Trafic / Nissan NV series (platform-dependent SCR systems)

OEM / Cross reference numbers:

• A0009053506
• A0009056900
• 0009053506 / 0009056900
• 5WK96681F / 5WK96681D (Continental sensor family references)

According to OE parts data, both A0009053506 and A0009056900 belong to Mercedes NOx sensor family used on Sprinter/Vito SCR systems, often differing by mounting position and calibration version.

FUNCTION:

• Measures nitrogen oxide (NOx) levels in exhaust gas
• Sends real-time data to ECU via CAN communication
• Controls AdBlue dosing for SCR catalyst efficiency
• Ensures Euro 6 emissions compliance

INSTALLATION POSITION:

• SCR system inlet or outlet (depends on vehicle configuration)
• Mounted on exhaust line near DPF/SCR catalyst assembly

IMPORTANT NOTE:
Mercedes Sprinter/Vito NOx sensors are position-specific (inlet vs outlet) and may look identical externally. Correct part number matching is critical to avoid:

• SCR/AdBlue warning lights
• Engine limp mode
• Incorrect NOx readings

FAQ:

Q1: Are A0009053506 and A0009056900 interchangeable?
A1: They are in the same sensor family but are often used for different SCR positions or revisions. Always match exact OEM number or VIN.

Q2: What vehicles use this sensor?
A2: Mainly Sprinter W906/W907 and Vito W447 diesel models with SCR systems.

Q3: What are failure symptoms?
A3: SCR warning light, AdBlue system faults, engine derate, limp mode, or NOx sensor error codes.

Q4: Is this a smart sensor?
A4: Yes, it includes integrated electronics and communicates via CAN bus.

Q5: Does it require programming after replacement?
A5: Some Mercedes models require SCR reset or ECU adaptation after installation.
