FAQ

Q1: Are 0281007018 and 0281007019 the same?
A1: They are a matched pair but not the same part.

• 0281007018 = upstream (before SCR catalyst)
• 0281007019 = downstream (after SCR catalyst)

Q2: What vehicles use this sensor?
A2: It is widely used on BMW diesel models including 1, 3, 4, 5, 6, 7 Series and X3–X6 SUVs equipped with SCR AdBlue systems.

Q3: What engine types are supported?
A3: Mainly BMW B47 (2.0L diesel) and B57 (3.0L diesel) engines with Euro 6 SCR emissions systems.

Q4: What does this sensor do?
A4: It measures nitrogen oxide (NOx) in exhaust gases and sends data to the ECU, which controls AdBlue injection to reduce emissions and maintain SCR efficiency.
