The NOx sensor is mounted in the exhaust with the NOx catalytic converter and measures the NOX value (NOX is created during a (high temperature) combustion process), from 1999 the EURO 3 emission standard for M1 vehicles (passenger cars) has come into force in the European Union. From that time, a diesel was allowed to emit a maximum of 0.50 NOx, from Euro 4 this has been reduced to 0.25 NOx, Euro 5 0.18 NOx and Euro 6 0.08 NOX. From Euro 6 standard, AdBlue is necessary to achieve the standard.
With a diesel, the NOx sensor works together with the Adblue system, depending on measured NOx catalysts, the Adblue projector injects more or less Adblue.
Unfortunately, the AdBlue system with many models is very susceptible and very expensive if it has to be repaired. Repair costs varies between 250 to 3000 euros depending on brand and part. If the NOx sensor gives a mistake, it may be that the sensor must be replaced. However, it may also be that the NOx catalyst
no longer works properly or the AdBlue system, which gives this error notification.
The AdBlue system has built a security system for many brands/models, if it no longer functions correctly or the Adbluet tank is empty, the car will count down and the engine can no longer be started to a x number of kilometers. Only with a suitable diagnosis tester can it be started once again and then for repair to
to drive the garage.
If the car drives in an emergency program or gives a motorcycle default and can therefore no longer be inspected or no longer be started after X km, then a software modification may be a solution, in most cases the entire AdBlue system should be deactivated because of a diesel because it Works together with the NOx sensor. This software modification should be viewed as a temporary fix. To fix the problem, or one must have the system removed from the license plate at the rdw. see below.
We received the information below from the RDW;
“The answer is that the removal (or deactivation) of the Adblue system, which is part of the emission control system, is considered a ‘change of construction’ under Vehicle Regulations.” If is changed then you are required to have the registration number updated by presenting the vehicle for inspection at an RDW inspection station. The emission values, established when the vehicle is admitted, are taken from the vehicle registration register. Unless demonstrated with certificates that the vehicle again
meet certain emission values. “
The deactivation of AdBlue system starts at 225 euros depending on brand and model. Returning the standard software due to repair is free of charge.
