4G0907807R SNS450 A2C39689300-001 NOX Sensor

4G0907807R SNS450 A2C39689300-001 Nox sensor

4G0907807R nitrogen oxide sensor is direct replacement to faulty genuine vw ag or continental part.

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 P229E P2202 P2200 U029E00 U029E U029D00 U029D, it means that NOX sensor has failed.

There is no need to spend a fortune for original continental part at dealer shop, when replacement part will do a job.

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 shop.

Continental SNS450 SME sensor fits many different VAG group car models.

Original VW Ag 4G0907807R sensor is also kwown as control unit with nox-sensor for emissions control.

DPF means diesel particulate filter and it is factory fitted to all diesel cars to ensure it complies with environmental regulation laws.

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.

You will find a list of the the most common error codes of nox sensor circuit faults.
