03C907807D NZA05-V4 SW422 NOXC3 NOX Sensor

03C907807D SW422 NZA05-V4 NOXC3 NOX Sensor to replace faulty NTK.

It is always recommended to fix this issue as soon as possible to avoid any damages to DPF filter, otherwise diesel particulate matter or soot can clog filter and it will cost you thousands to fix.

SW422 NZA05-V4 DC 12V sensor is factory fitted to many different VAG group cars.

NOX stands for Nitrogen Oxide.

Error cleaning may be required, but just once after fitting new NOX sensor, it can be done by yourself, no need to visit car dealer.

VW Audi 03C907807D sensor is also kwown as control unit with nox-sensor for emissions control.

DPF means diesel particulate filter.

What does nox sensor do ?

A nitrogen oxide sensor in short NOX is high temperature part is used in cars to detect and measure out amount of this compound (nitrogen oxides) coming out of exhaust system to ensure, it is mostly found in diesel cars.

Replacement sensor probe with ballast unit will save you a fortune, solve your NOX problems and you will comply with enviromental emissions laws again.

03C907807D part number supersedes and is compatible with 03C907807A and 03C907807C.
