Compatible with Mercedes-Benz heavy-duty diesel trucks equipped with SCR emission systems (Euro 5 / Euro 6 applications depending on engine variant), including:

• Actros
• Atego
• Axor (some configurations)
• Econic (some configurations)

OEM reference numbers: 5WK96616F, A0091533628.
Used in diesel exhaust aftertreatment system for NOx monitoring (AdBlue/DEF SCR system).
Installed in exhaust system (commonly upstream or downstream of SCR catalyst depending on configuration).
24V system sensor used in CAN-based emissions control.
Fitment must be confirmed by OEM number, engine model (OM906/OM936 etc.), and SCR layout before installation.

FAQ:

Q1: How do I confirm compatibility?
A1: Match OEM numbers 5WK96616F or A0091533628 with your original sensor and confirm connector type, cable length, and SCR system position (inlet/outlet).

Q2: Where is this NOx sensor installed?
A2: It is installed in the SCR exhaust aftertreatment system on Mercedes commercial vehicles, either before or after the catalytic converter depending on configuration.

Q3: What are common failure symptoms?
A3: Check engine light, SCR/AdBlue fault codes, incorrect NOx readings, reduced engine power, or limp mode.

Q4: Is this sensor used across all Actros/Atego models?
A4: No. Different engine generations use different NOx sensors, so OEM number matching is required.

Q5: Does replacement require programming?
A5: Some models require diagnostic reset or SCR system adaptation after installation.
