Product Information
Full details
The Hella AdBlue NOx Sensor (6PN 358 307-251) is a critical emission control component designed for Mercedes-Benz owners looking for a high-quality, reliable replacement for faulty nitrogen oxide sensors. This sensor ensures your vehicle meets strict emissions compliance and operates within optimal parameters by accurately measuring NOx levels in the exhaust stream. While it is built to exact OEM specifications, users must be aware that professional installation and potential software re-calibration are required to ensure the vehicle's electronic control unit correctly recognizes the new sensor.

FAQs
Can I install this sensor myself?
Professional installation is strongly recommended because the sensor requires specialized diagnostic software to calibrate the system after physical installation.
What OEM part numbers is this compatible with?
It is compatible with OEM numbers including 000 905 34 03 and 000 905 51 00.
Does this sensor come with a harness?
The sensor includes a 390mm integrated cable and connector as part of the assembly.
Why does my car need a software update after replacing the sensor?
Modern Mercedes-Benz control units must be told that a new sensor has been installed to clear historical fault logs and reset the adaptive learning parameters for emissions.
What happens if I don't calibrate the sensor?
The vehicle may continue to display emission-related fault codes, and in some cases, the engine may remain restricted in performance mode.
Troubleshooting
Check Engine light remains illuminated after installation
The sensor requires a software reset or calibration via an OBD-II diagnostic tool to sync with the ECU.
Sensor signal error codes persist
Check the 5-pin connector for bent pins or debris; ensure the electrical connection is fully seated and clicked into place.
Pros and Cons
Pros
- Meets or exceeds OEM quality standards
- Ensures compliance with vehicle emission regulations
- Reliable signal output for the vehicle control unit
- Direct fit for specified Mercedes-Benz models
Cons
- Requires professional installation for valid operation
- Often necessitates post-installation software reset or training
- Incompatibility with non-listed vehicle models
Setup, Compatibility & Care
This sensor is specifically intended for professional use. Installation involves accessing the exhaust system, which requires a lift and proper safety equipment. Ensure the electrical connector is clean and free of corrosion before mating it with the 5-pin harness. Once installed, the vehicle's diagnostic software must be utilized to clear old fault codes and perform a 'teach-in' or calibration process so the Engine Control Unit (ECU) recognizes the new component. Failure to perform this software step will result in the vehicle failing to reset its emission status.
