FAQ

Q1: What is A0009051512 used for?
A1: It is a NOx sensor used in Mercedes-Benz diesel vehicles equipped with SCR (AdBlue) systems. It measures nitrogen oxide levels in the exhaust to help control emissions.

Q2: Which models use this sensor?
A2: It is commonly found on Mercedes C-Class (W205), E-Class (W212/W213), and some Sprinter diesel Euro 6 models depending on engine configuration.

Q3: Is this inlet or outlet sensor?
A3: It is used as a rear or downstream NOx sensor in many applications, but placement can vary depending on exhaust layout and engine version.

Q4: What does this sensor do?
A4: It monitors NOx levels in the exhaust system and sends data to the ECU, which adjusts AdBlue dosing to reduce emissions and maintain SCR efficiency.
