What is Adblue off; Everything about Adblue delete tools and software

 AdBlue Removal: Everything You Need to Know About AdBlue Off, Adblue Kits and Adblue off tools and software.

What Is the AdBlue System and How Does It Work?

AdBlue is a diesel exhaust fluid (DEF) used in Selective Catalytic Reduction (SCR) systems to reduce harmful nitrogen oxide (NOx) emissions in diesel engines. It is composed of 32.5% urea and 67.5% deionized water. When injected into the exhaust stream, AdBlue reacts with NOx and converts it into nitrogen and water vapor, which are harmless to the environment. This system helps meet stringent emission regulations, especially in Euro 5 and Euro 6 vehicles.

What Are the Components of the AdBlue System?

The main components of an AdBlue system include:

• AdBlue Tank: Stores the urea solution.
• Injector: Injects AdBlue into the exhaust stream.
• SCR Catalyst: Where the chemical reaction takes place.
• NOx Sensors: Monitor the effectiveness of NOx reduction.
• AdBlue Pump and Control Unit: Manage the flow and pressure of the fluid.

Where Is the AdBlue System Located?

The AdBlue tank is usually located near the fuel tank, while the SCR catalyst and injector are placed within the exhaust system. Sensors and control units are distributed throughout the exhaust and emission system to manage the process.

 

Does the AdBlue System Reduce Power/HP?

While the AdBlue system is primarily designed for emission control, some users report a slight reduction in engine responsiveness or performance due to added complexity in the exhaust system.

 

What Is AdBlue Delete?

AdBlue delete, also known as AdBlue off or AdBlue removal, is the process of disabling the vehicle's SCR system to prevent the use of AdBlue or DEEF/ DEF. This is often done by modifying the vehicle's ECU file.

 

Why Is AdBlue Off Done?

If you also own a truck or vehicle that's frequently troubled by AdBlue system issues, constantly dealing with check engine lights, DTCs, and the high cost of purchasing AdBlue fluid, then you probably understand better than anyone why AdBlue Off / AdBlue Delete might be necessary!

Reasons for performing AdBlue off include:

High cost and frequent refills of AdBlue.

Avoiding warning lights, Adblue related DTCs and system failures.

Use in regions without strict emission regulations.

Vehicle operation in remote areas with no AdBlue availability.

 

How Is AdBlue Off Performed?

AdBlue off can be done in two ways:

AdBlue Removal Kits: These plug-and-play modules simulate sensor readings and bypass the SCR system. However, they are generally unreliable and risky. AdBlue delete kits also definitively void the warranty.

ECU Tuning: The preferred and more reliable method is modifying the ECU software to disable AdBlue functions. This is done by reading the ECU file, remapping/ modifying it using professional software, and writing/ Reflash it back to the ECU.

 

AdBlue Off via ECU Tuning:

As mentioned earlier, there are methods like using AdBlue removal kits aimed at disabling the AdBlue system. However, in general, AdBlue Off / AdBlue Delete through ECU tuning involves the following steps:

Reading the vehicle's ECU file (preferably the original file) using ECU tuning tools / ECU programming tools. (Note: Depending on your vehicle model and its ECU type, you may sometimes need to disconnect certain plugs and connectors).

Modifying the file using software such as WinOLS or Swiftec and disabling the AdBlue area and switches within the ECU map.

Writing the modified file back into the ECU. This method offers a clean and integrated solution without physical tampering.

 

Pros and Cons of AdBlue Off:

Pros:

• Reduced maintenance costs.
• No need to refill AdBlue.
• Avoid Adblue/ SCR-related faults.

 

Cons:

• Potential legal issues.
• Failing emissions tests.
• Voiding warranty.

Pros and Cons of AdBlue Off Through ECU Tuning

Pros:

• Seamless integration.
• No need for external modules.
• Customizable for performance tuning.

 

Cons:

1. Requires skilled tuners.
2. Still may affect warranty.

 

AdBlue Off Software:

Popular ECU tuning software includes:

WinOLS: Advanced map editing with extensive plugin support.

Swiftec: User-friendly interface with many automated solutions for AdBlue off and other deletes.

 

AdBlue Off Tools:

While tools aren’t directly used for removal, they are necessary to read and write ECU files. Common tools include:

KESS3 (by Alientech)

Dimsport New Genius/New Trasdata

Magic Motorsport Flex

These tools communicate with the vehicle's ECU over OBD or bench/boot mode.

 

Does AdBlue Off Void the Warranty?

Considering the two main methods for performing AdBlue Off, as mentioned above, AdBlue Off kits definitely void the warranty. However, when it comes to AdBlue Off through ECU tuning, this usually doesn’t happen, since in most cases, dealerships are unable to detect these software modifications.

Although there are still some risks and concerns about voiding the warranty even with ECU tuning, overall, the likelihood of voiding the warranty through ECU tuning is significantly lower compared to using kits.

 

Is AdBlue Off Legal or illegal?

This entirely depends on the national and local laws of your city or country of residence. In some cities and countries, due to strict emission standards, this practice can be illegal, while in many other places, there are no restrictions and it is considered legal.

However, there are permits and exceptions for off-road and race vehicles.

DTCs Related to the AdBlue System:

Common DTCs include:

P Codes:

• P204F (Reductant System Performance)
• P207F (Reductant Quality Performance)

SPN Codes:

• SPN 3364 (Aftertreatment 1 SCR Conversion Efficiency)
• SPN 4334 (SCR Line Heater)

KWP Codes:

• Specific to OEM diagnostic tools

Manufacturer Codes:

• Vary by brand (e.g., Mercedes 16C600 for AdBlue malfunction)

 

AdBlue Off through ACM

ACM (Aftertreatment Control Module) is used in some trucks like Freightliner, Volvo, and Scania. In these vehicles, AdBlue off may require reprogramming the ACM in addition to the ECU, since the ACM directly manages SCR functions.

 

AdBlue Removal Kit: Good or Bad?

Generally, AdBlue removal kits are not recommended. They can trigger system errors, reduce reliability, and clearly void warranty. ECU tuning is a more professional approach.

 

Does AdBlue Off Affect DPF and EGR Systems?

No direct effect, but these systems are part of the overall emission strategy. If DPF or EGR issues arise, they must be addressed separately or removed via tuning as well.

 

What Is AdBlue Reduction?

AdBlue reduction refers to strategies that minimize AdBlue consumption through tuning without fully disabling the system. It’s a less aggressive approach than AdBlue off.

 

Can AdBlue Removal Increase Power/HP?

In itself, AdBlue off does not significantly increase horsepower. However, combining it with performance ECU tuning can lead to better throttle response and power gains.
