FAQs

What is an AdBlue NOx Sensor?

An AdBlue NOx Sensor measures the level of nitrogen oxides (NOx) in the exhaust gases of a vehicle. This information is used by the vehicle's computer to control the injection of AdBlue (Diesel Exhaust Fluid) to reduce harmful NOx emissions through a process called Selective Catalytic Reduction (SCR).

Which Mercedes-Benz models is this sensor compatible with?

This Hella sensor (6PN358307-201) is compatible with specific models including GLC (2015-2019), Vito 119 CDI / 119 BlueTEC, GLS 350 d 4-matic, Vito 116 CDI / 116 BlueTEC 4-matic, and C-Class C 220 d 4-matic.

What does 'Control Unit/Software must be trained/updated' mean?

This means that after installing the new sensor, a mechanic needs to use specialized diagnostic tools to inform the vehicle's computer system that a new sensor has been fitted and calibrate it to work correctly. Simply plugging it in is not enough.

Can I install this sensor myself?

Installation requires qualified personnel due to the complexity and the necessity of subsequent software training/updates. It is highly recommended to have a certified mechanic perform the installation.

What is the cable length of this sensor?

The cable length for this Hella NOx sensor is 790 mm.

What is the thread size for this sensor?

The thread size is M20X1.5.

What are the equivalent OE part numbers?

The OE numbers this sensor is designed to replace are 000 905 02 08 and 000 905 29 09 (MERCEDES-BENZ), including their 'A' prefixes.

Troubleshooting

Check engine light or AdBlue warning light is illuminated.

This can be caused by a faulty NOx sensor, wiring issue, or AdBlue system problem. Ensure the sensor is correctly installed and that the control unit/software has been properly trained. If issues persist, further diagnosis of the SCR system is required.

Sensor not recognized by the vehicle after installation.

The vehicle's control unit/software likely requires training or an update to recognize the new sensor. This must be performed by a qualified technician.

Inaccurate NOx readings reported.

Verify correct sensor installation and ensure no physical damage. Confirm that the software is up-to-date and properly configured for the sensor. Contamination within the exhaust system can also affect readings.

Pros and Cons

Pros

  • Ensures compliance with emissions regulations.
  • Supports efficient AdBlue system operation.

Setup, Compatibility & Care

Compatibility:

This sensor is specifically designed for the following Mercedes-Benz models:

  • GLC (2015-2019)
  • Vito 119 CDI / 119 BlueTEC
  • GLS 350 d 4-matic
  • Vito 116 CDI / 116 BlueTEC 4-matic
  • C-Class C 220 d 4-matic

Always verify compatibility using your vehicle's VIN or by cross-referencing the OE part numbers: A 000 905 02 08 or A 000 905 29 09.

Installation:

Installation of this AdBlue NOx sensor requires qualified personnel. It is essential to follow the manufacturer's recommended procedures. Crucially, after installation, the vehicle's control unit/software must be trained or updated to recognize and correctly utilize the new sensor. Failure to perform this step can result in incorrect readings, system errors, or the sensor not functioning at all.

Care:

  • Handle the sensor with care during installation to avoid damaging the sensor element or the connector.
  • Ensure the M20X1.5 thread is clean before installation to achieve a proper seal.
  • Protect the sensor and its wiring from excessive heat, moisture, and physical damage during and after installation.
  • Regularly check for any dashboard warnings related to the emissions system, which may indicate a need for inspection.
