FAQ

Q1: What is the function of this NOx sensor?
A1: It measures nitrogen oxide levels in diesel exhaust and sends data to the SCR system to control AdBlue (DEF) injection and reduce emissions.

Q2: Where is it installed?
A2: It is installed in the exhaust aftertreatment system, typically on the SCR catalyst line depending on engine layout (2.0 TDI or 2.5 TDI).

Q3: Are these part numbers interchangeable?
A3: 03L907807AB, 076907807A, and 5WK96690B are cross-reference OEM/Continental numbers for the same sensor family, but exact matching is still required for correct calibration and plug/harness type.

Q4: Is this used on all Crafter models?
A4: It is mainly used on Crafter 2E / 2F platforms (2006–2016) with 2.0 TDI and 2.5 TDI engines, but fitment depends on emission system configuration.

Q5: What are common failure symptoms?
A5: Engine warning light, AdBlue/SCR system faults, NOx sensor communication errors, or reduced engine power (limp mode).
