Turn off the AdBlue system
Modern specialized equipment must comply with environmental requirements and comply with the norms for the amount of harmful substances in the exhaust. For these purposes, new engineering solutions are used. These include Adblue, which is used to neutralize toxic substances. Is it possible to disable the AdBlue system without serious consequences?
How AdBlue works
The AdBlue converter is used in the system of diesel vehicles. This reagent enters the outlet pipeline. Then, due to catalytic reactions, nitric oxide and ammonia are converted into harmless nitrogen and water vapor.
The composition of the aqueous solution includes highly purified urea. Adblue is used in conventional technology, as well as in specialized, agricultural. Without a reagent, the engine runs at low power, produces a low number of revolutions. The risk of failure of the entire unit increases.
Consequences of a malfunction of the AdBlue system
Liquid reagent directly affects the correct management of transport. The fact that a malfunction has occurred can be understood by noticeable signs:
- significant reduction in engine power;
- increased smoke volume;
- atypical motor operation.
Reasons for these reactions include:
- liquid freezing in winter even at -100 C;
- natural wear and tear – a certain working resource is laid in the system;
- poor quality liquid, with impurities.
Therefore, in order to avoid unnecessary expenses and nervous shocks, the AdBlue system is turned off.
Why is the AdBlue system disabled?
The main reason to disable adblue is the high cost of system maintenance. The liquid is consumed quickly – it is not cheap. It is necessary to fill the solution every 6-10 thousand run.
Only the original product is intended to be used. There is no way to save on cheap analogues, because they have an extremely negative effect on other mechanisms – they clog the catalyst, clog the particulate filter, and more.
The second argument in favor of disabling the AdBlue urea system is its complexity, which includes many elements. The control unit, dosing and liquid level sensors often fail. This is especially true in regions with cold winters. For full-fledged work, only original spare parts are required, which sometimes complicates repairs.
Programmatically disable AdBlue
To disable the system, you need to reprogram the electronic control unit so that the internal combustion engine does not respond to signals from ecosystem sensors. However, this option is not suitable for everyone, for example, in the EU countries its presence is mandatory.
If there is a need to disable AdBlue, then you need to follow these steps:
- computer diagnostics;
- copying the factory firmware in case you need to restore it;
- correction of ECU firmware;
- The new program is installed in the ECU.
It is better to entrust such a process to experienced professionals who have the opportunity and resources to carry it out efficiently. The price of software shutdown of the AdBlue system is calculated based on the type of equipment, the device of the control unit, the complexity of reprogramming.
