Software Deactivation of AdBlue System
Car manufacturers are constantly inventing and implementing devices and schemes that reduce the toxicity of their engine emissions. One such technology is AdBlue, designed to reduce the level of nitrogen oxides in exhaust gases. Unfortunately, this system doesn't always work correctly and adequately, and sometimes it frankly becomes the cause of problems. That's when the service of AdBlue removal in Warsaw, provided by STS company, becomes relevant for drivers.
What is AdBlue
AdBlue is the name of one of the most common brands of reagent fluid. The correct name for this system is SCR (Selective Catalytic Reduction). Its purpose is to significantly reduce nitrogen oxide (NOx) emissions in diesel engine exhaust gases by up to 90%. Initially, it was installed on heavy-duty vehicles, but with the introduction of Euro V and VI environmental standards, it began to be implemented on small commercial and even passenger cars.
The principle of SCR operation:
- The reducing agent (AdBlue or analogues) is injected into the exhaust gas flow through a catalyst device installed in the exhaust system.
- A chemical reaction occurs that converts nitrogen oxides into natural components of air: nitrogen, carbon dioxide, and water.
The nitrogen oxide reducer consists of 67.5% deionized water and 32.5% highly purified urea. Besides the AdBlue trademark, which has become generic, registered by the German Association of the Automotive Industry (VDA), a similar fluid may be called AUS 32 (Aqueous Urea Solution) or DEF (Diesel Exhaust Fluid).
Most often in modern cars, SCR is installed along with exhaust gas recirculation systems (EGR) and diesel particulate filter (DPF). These environmental helpers have also earned many fair complaints for unstable and incorrect operation. Therefore, for the owner of a car equipped with AdBlue in Warsaw, it would be logical to combine its deactivation with the removal of the EGR valve and a quality cleaning of the particulate filter at STS company.
Symptoms of AdBlue Problems
Despite the good engineering concept, in practice, the operation of the SCR system is associated with great difficulties. Its sensors, pump, and nozzles that spray AdBlue often fail. The fluid has the property of freezing (crystallizing) at low temperatures, and after prolonged storage in the cold, it often loses its properties. The urea solution needs to be refilled in a separate filler neck, and it's not available at all gas stations.
Signs of AdBlue system malfunction:
- Appearance of Check Engine errors on the dashboard;
- Message requiring to add AdBlue, despite its presence;
- Messages with a countdown of kilometers to forced vehicle stop;
- Computer speed limitation;
- Noticeable decrease in engine power.
In some cases, problems are solved by adding fluid or defrosting the system, but if the malfunction is more serious, the car may lose the ability to move on its own even to the place of AdBlue repair in Warsaw.
When to Deactivate the System
As we can see, when there are problems with the AdBlue system, the car's ECU significantly limits the vehicle's operation – even to the point of complete impossibility of use. Troubleshooting is expensive, as it is mainly carried out in dealerships. At the same time, there is no guarantee that they will not appear again. In addition, the SCR system itself also involves additional costs. This includes the constant purchase of AdBlue fluid and increased fuel consumption.
Therefore, STS company recommends all its clients to use our AdBlue deactivation services in Warsaw and do it without delay and without hesitation.
How the Software Deactivation Process Takes Place at STS Parts
For ECU reflashing, we use equipment from the best companies in the chip tuning industry and our own developed software. The procedure is divided into several stages:
- Diagnostics of the SCR system for malfunction.
- Creating a backup copy of the stock firmware.
- Software correction.
- Uploading a new edited version of the firmware to the ECU.
- Checking the operation of the car's systems.
At the same time, we physically remove the AdBlue catalyst from the exhaust system. Thus, the exhaust gases freely exit without encountering resistance, the system stops giving errors, and the engine gets full power.
Advantages of AdBlue Deactivation at STS Parts Warsaw
Before telling you about the advantages of working with us, let's consider other ways to deactivate the system:
- Using an emulator. An inexpensive device is connected to the CAN bus to disable the supply of urea to the exhaust system. Although the advertising for these devices guarantees successful operation even in the presence of errors in the system, in reality, the emulator very poorly imitates the operation of sensors. Usually, the device needs to be installed in places where it is poorly protected from moisture and dirt (frame, bottom of the body), and therefore will not work for long.
- Self-flashing of the ECU to lower standards using software from the internet. This is associated with great risks: firstly, such programs usually have an unknown origin, and secondly, their installation requires high programmer qualifications. Otherwise, reflashing can seriously harm the car and its owner.
Therefore, it's better and safer to turn to where qualified specialists work, who have experience and special equipment – to STS Parts. The procedure for deactivating the AdBlue system in Warsaw takes no more than 2-3 hours, including diagnostics of the car before and after the procedure.
Frequently Asked Questions
On which cars can the AdBlue system be deactivated?
Our company can programmatically disable SCR wherever it is installed – on any diesel vehicles.
Is it safe for the car?
Deactivating AdBlue does not cause any harm to the car; on the contrary, the engine becomes more powerful and works more stably.
Will I need to add AdBlue fluid after software deactivation?
Of course not, because the system will no longer work and reagents will not be needed either.
Is it legal to remove AdBlue from a car?
STS Parts does not engage in illegal operations. Moreover, the SCR system will not be removed, but programmatically disabled. At the client's request, its functionality can be restored at any time.
Problem: In the case of a critical discharge of a low-voltage battery (12–48 V), the electronics prevent charging because it is dangerous with Li-Ion batteries. The manufacturer recommends discarding fully functional batteries and replacing them with new ones. This is expensive.
Problem: We received an electric car with very discharged traction batteries. The problem is typical for the Fiat 500. During idle time, the batteries discharged below the permissible level, and the car's electric motor stopped starting.

Problem: Failure of Toyota hybrid batteries is a common problem that our customers come to us with. The battery cells degrade, making it impossible for the car to operate normally.
Problem: Land Rover Range Rover Sport 3.0 SDV6 Hybrid AT AWD - the hybrid system did not work, the VBB was in emergency mode. The car was running only on diesel fuel, the low-voltage battery was not charging.
Problem: None of the car's systems were working at all, it wasn't even possible to raise it on a lift because the air suspension didn't activate either. I had to install the Porsche near the repair box on "goat" stands.
Problem: Errors P0AA6, P1F0E - high voltage charging system service
Problem: The problem with the car was the incompatibility of the Chinese GB/T standard charging system with European charging stations. This created difficulties for the owner of the Audi Q4 e-tron, since the car, produced for the Chinese market, could not charge at European stations with the required speed and reliability.

Problem: The Hyundai Kona made a rather loud noise. The customer diagnosed the malfunction on his own - in his opinion, the gearbox was the cause of the extraneous sounds.
Problem: There was water and rust inside the rail, which damaged both the needle bearing in the cover and the torque sensor, i.e. both the mechanical and electrical parts
Problem: The client complained about a knock at the bottom – it was as if a gnome was sitting there with a hammer and hitting plastic with it. However, the dwarf did not always do this, mainly after an energetic ride. Then, the sound could disappear and reappear with a new sharp push on the pedal.
Problem: Destruction (wear) of differential satellites and, as a consequence, noises (hum) when driving the vehicle.

Problem: The owner of a Citroen C4 Picasso car came to us with a complaint about poor engine performance. The car literally could hardly drive: the engine would not rev above 2000 rpm and did not develop the necessary power. Fuel consumption increased significantly. The problem lies in the car's clogged particulate filter.
