03L907807R 5WK96737 NOX Sensor

03L907807R 5WK96737 NOX sensor

03L907807R Nitrogen Oxide sensor is factory fitted to VW Volksagen Seat and Audi cars with diesel engine.

If you have did on-board computer scan after seeing check engline light on the dashboard and your car is showing any of these error codes P229F62 P229F P2202 U029E00 U029E U029D00 U029D, it means that NOX sensor has failed.

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.

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 dealer.

03L907807R 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.

Dealer will charge you over £500 for a single sensor.

Direct replacement to old faulty genuine VW Ag 03L907807R Continental 5WK96737 NOx sensor.
