This is a Mercedes SCR NOx sensor used in Euro 6 diesel exhaust aftertreatment systems, responsible for measuring nitrogen oxide levels and controlling AdBlue injection.

FUNCTION:

• Measures NOx concentration in diesel exhaust gas
• Sends real-time data to ECU via CAN communication
• Controls SCR/AdBlue dosing strategy
• Monitors catalyst efficiency and emissions performance
• Ensures Euro 6 compliance and prevents engine derate

INSTALLATION POSITION:

• SCR system inlet or outlet sensor (depends on vehicle configuration)
• Mounted on exhaust line between DPF and SCR catalyst or after SCR system

IMPORTANT NOTE:
A0009058111 belongs to a large Mercedes NOx sensor family, meaning:

• Same external design but different internal calibration versions
• Inlet and outlet sensors are NOT interchangeable
• ECU software defines correct usage (not just part number)

Incorrect matching may cause SCR faults, AdBlue warnings, or limp mode.
