LUMRO NS11A NOx sensor repair kit fits all cars such as VW Audi Mercedes-Benz BMW Citroean Renault Peugeot GM Opel Vauxhall and many other.

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 P229F63 P229F P229E P20EE00 P229e00 P229F00 P2200 P2201 P2202 P2203 P2204 P11DC P11DB P11CC P20EE P2BAD P220B00 it means that genuine NGK NOX sensor probe also called as lambda sonda has failed and needs to be replaced.

If you are getting the following error fault message Lost communication with NOX sensor A or B, it means that you must replace whole unit, because main box has failed.

Each car manufacturer has different name for SCR system, for example VW call it BlueMotion and sensors have NOxC3 or NOxC4 letters, Mercedes Benz call it BlueTec and so on.

Another major thing which mercedes-benz passenger cars have compared to Audi, Volkswagen, Renault, BMW etc. are that there are two exhaust gas sensors, these sensors are called bank 1 sensor 1 or sensor 2, one of them is located upstream and other one downstream.

The front NOX sensor before the catalytic converter is usually called 'upstream' on start xentry software diagnostic tool or Sensor 1. The rear sensor installed after the catalytic converter is called 'downstream' or Sensor 2.

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

The reason Diesel Particulate Filter can clog up is that NOX sensor is controlling SCR system how much liquid urea (AdBlue) needs to be injected via nozzle to exhaust system and if there is not enough urea being injected the more particulates are going to be left inside filter and it can cause damage to catalytic converter.

NS11A probe is used for many different motor vehicles such as: Bus, Coaches, Tractors, Passenger Cars, Trucks and many other.

All well known brands are using emission control NOx sensors to make sure they comply with environmental laws including brands like Cummins Volvo DAF XF Iveco Isuzu BMW Renault Citroen Peugeot Renault Mack Kenworth SCANIA MAN Mercedes-Benz Dodge VW Audi Porsche Seat Skoda and many many other.

What does SCR means ?

SCR in short means - Selective Catalytic Reduction and it is an advanced new active emissions control technology system that injects AdBlue also known as a liquid-reductant agent through adblue injector nozzle into the exhaust system.

Adblue is also called as Diesel Exhaust Fluid (DEF) and the reductant source is usually automotive  grade urea DEF or AdBlue, whatever name you call both are the same meaning and used for the same  purpose to make our enviroment much more cleaner and comply with strict environmental regulation laws worlwide.

To reach strict automotive environmental laws SCR and AdBlue system is manditory, because cars without this system can't get EURO5 or EURO6 certificate.

NOX stands for Nitrogen or Nitrous Oxide.

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

The whole ballast unit with probe sensor is also kwown as control unit with nox-sensor for emissions control.

DPF means diesel particulate filter.

What does nox sensor do on motor vehicles?

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.

This part is combination of lambda oxygen sensor and NOx sensor, two in one.

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

Can you drive with bad NOx sensor?

The answer is yes, but you need to put two things into consideration. The first one you are breaching laws and if checked by goverment officials you could get big fine depends on the motor vehicle you are driving truck, bus, coach, tractor or passenger car as each of them has different regulations. 

Second thing you are risking is to do some more problems for your motor vehicle like described above clogging up DPF filter, causing isues to SCR exhaust sytem and ofcourse when NOx sensor is faulty fuel consumption goes up, because the engine can't properly calculate how much does it need to inject fuel petrol or diesel via injector nozzles.

Dealer will charge you £500 or even more for a single sensor with ballast unit, which is not faulty.

Below you'll find a list of siemensVDO, Continental and other car manufacturer part numbers, which could be fixed with our replacement sensor head.

Additionally to make sure that you are buying correct item, we have collected the most common Diagnostic Trouble Codes  - DTC for engine management ligh (EML).

VW Ag brand emission control units have some different names on them like NOxC3, NOxC4 or SME, other brands use words like SNS and so on, it's just names used by manufacturer and LUMRO NS11A sensor will fit.

There are many different variations of fault codes related to NOx sensors and some car manufacturers use different codes to identify them.

For example mercedes benz cars mostly use P229F63 P229F P2202 P2201 error codes, VAG group cars like audi vw skoda seat porsche mostly pop out P229E P229F, GM group cars like Opel Vauxhall Insignia 2.0 CDTi Zafira 1.6 CDTi Chevrolet Chevy show the following codes P11DC P11DB P11CC P20EE P2BAD and so on.

The most important thing when diagnosing faulty part specially for NOx sensor is to make sure error code relates 100% directly to NOx sensor, not any other part used in the NOx system for example NOx sensor heater, yes it says NOx sensor, but later on it says heater so this kind of error is definitely not related to sensor control unit or probe.

Error codes when NS11A sensor probe won't solve an issue:

  • Lost communication with sensor A or B

Error codes, which can be fixed with NOX probe:

  • P229F
  • P229FE1
  • P229F09 nox sensor 2 cylinder bank 1 has a malfunction there is a component fault
  • P229F28 - Nox sensor2 cylinder bank 1 has malfunction
  • P229F62 Signal of NOx sensor implausible
  • P220400 the nox sensor (cylinder bank 1) has a sporadic malfunction._
  • P220000 the nox sensor (cylinder bank1) has an electrical fault._
  • P229F63
  • P229F00
  • P229F09
  • P229E - NOx Sensor Circuit Bank 2
  • P229E00

  • P2201
  • P2202
  • P2203
  • P2204
  • P220162
  • P1033 Nitrogen Oxides Sensor Signal Too Low
  • P11DC - NOx Sensor Current Performance Bank 1 Sensor 2
  • P11DB - NOx Sensor Current Performance Bank 1 Sensor 1
  • P11CC - Nox Sensor 1 Performance Signal Low
  • P20EE - Nitrogen Oxide (Nox) Catalyst Efficiency below Threshold
  • P2BAD - Exhaust Nitrogen Oxide (NOx) Concentration high
  • P220B00
  • P22A021 - NOx sensor 2 (cylinder bank 1) has a short circuit to ground. The signal amplitude is less than the minimum amplitude
