AdBlue Removal

AdBlue removal is possible by modifying the vehicle software. Its components and the derived error codes are also deactivated.

* Important! Consult the current legislation in your country.

As regulations on vehicle emissions become stricter, many vehicle owners are turning to AdBlue, a diesel exhaust fluid (DEF) designed to reduce harmful emissions. However, some vehicle owners are also considering AdBlue removal. We will explore the pros and cons of AdBlue removal, as well as the potential consequences of removing AdBlue from your vehicle.

What is AdBlue?

AdBlue is a DEF solution composed of 32.5% urea and 67.5% deionized water. It is a non-toxic, odorless, and colorless liquid that is injected into the exhaust system of diesel vehicles to reduce harmful nitrogen oxide (NOx) emissions. AdBlue is a registered trademark of the German Association of the Automotive Industry (VDA).

How does AdBlue work?

When AdBlue is injected into the exhaust system, it breaks down into ammonia and carbon dioxide. The ammonia then reacts with the NOx emissions, converting them into nitrogen and water, two harmless substances that are released into the atmosphere.

Why would someone consider AdBlue removal?

There are several reasons why someone might consider AdBlue removal. One reason is that AdBlue can be expensive, especially for vehicle owners who drive long distances. Another reason is that AdBlue can be difficult to find in some regions, which can make it inconvenient for vehicle owners to refill their AdBlue tanks. Additionally, some vehicle owners believe that AdBlue is a hassle and would rather not deal with it.

Legal consequences of AdBlue removal

AdBlue removal is illegal in many countries, including the United States and most of Europe. In the United States, tampering with emissions control systems is a violation of the Clean Air Act and can result in significant fines. In Europe, AdBlue removal can result in a failed MOT (Ministry of Transport) inspection, which can prevent vehicle owners from renewing their registration.

Pros of AdBlue removal

The primary benefit of AdBlue removal is cost savings. Vehicle owners who remove AdBlue from their vehicles no longer have to purchase AdBlue, which can save them money in the long run. Additionally, removing AdBlue can improve fuel efficiency, which can result in additional cost savings.

Cons of AdBlue removal

While AdBlue removal may seem like a cost-effective solution, it can have several negative consequences. The most significant con of AdBlue removal is increased emissions. Without AdBlue, nitrogen oxide emissions can increase significantly, which can harm the environment and contribute to air pollution. Additionally, AdBlue removal can void the manufacturer’s warranty and may result in fines or legal consequences.

Can AdBlue be replaced with something else?

While AdBlue is the most common DEF solution, there are alternatives available. One alternative is Diesel Exhaust Fluid 2.5% (DEF 2.5%), which contains less urea and is less effective at reducing NOx emissions. Another alternative is a DEF delete kit, which is designed to bypass the AdBlue system entirely.

AdBlue removal process

The process of removing AdBlue from a vehicle involves bypassing the AdBlue system entirely. This can be achieved through the installation of a DEF delete kit, which is typically performed by a professional mechanic. The kit includes a device that disables the AdBlue system, as well as instructions on how to remove the AdBlue tank and associated hardware. It is important to note that AdBlue removal is a complex process that should only be performed by a trained professional.

Consequences of AdBlue removal on the environment

AdBlue removal can have significant consequences on the environment. Without AdBlue, nitrogen oxide emissions can increase significantly, contributing to air pollution and harming the environment. Additionally, AdBlue removal can result in decreased fuel efficiency, which can lead to increased greenhouse gas emissions and further environmental harm.

How to maintain AdBlue system in your vehicle

To maintain the AdBlue system in your vehicle, it is important to follow the manufacturer’s guidelines for AdBlue usage and refilling. This typically involves refilling the AdBlue tank at regular intervals and monitoring the AdBlue levels to ensure that the system is functioning properly. It is also important to avoid using contaminated AdBlue, as this can damage the AdBlue system and result in costly repairs.

AdBlue removal vs. ECU remapping

ECU remapping is another popular method for increasing vehicle performance and fuel efficiency. Unlike AdBlue removal, ECU remapping involves modifying the vehicle’s engine control unit (ECU) to optimize performance and efficiency. While ECU remapping can result in cost savings and improved performance, it is important to note that it can also void the manufacturer’s warranty and may have legal consequences.
