What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio feedback to the engine control module
• Slow or unstable sensor response during closed-loop operation
• Emission test failures tied to exhaust monitoring faults
• Driveability issues caused by inaccurate exhaust oxygen readings

Installation Notes and Tips

• Verify the connector shape, wire count, and sensor position before ordering.
• Confirm thread size M18x1.5 and cable length 420 mm against the original sensor.
• Use the vehicle-specific fitment notes for side and position details, especially on Mercedes-Benz front right and front left applications.
• Inspect the exhaust bung and wiring routing before installation to avoid strain on the harness.
• For fitment examples, this part fits 2012-2016 Mercedes-Benz SLK55 AMG, front right; fits 2006-2015 Mercedes-Benz ML350, front; and fits 2014-2015 Mercedes-Benz Sprinter 2500, upstream.

Quality Assurance

Vemo V30-76-0038 is built as an aftermarket emission control sensor with application-specific dimensions and connector design for the listed Mercedes-Benz and Dodge Sprinter fitments. The pre-greased thread and OE-style configuration support proper sensor replacement when matched to the correct vehicle and position.
