What Are the Differences in AdBlue Fault Solutions?

What Are the Differences Between AdBlue Disable From the ECU and AdBlue Disable With an Emulator?

The AdBlue system is an emission reduction system found on every diesel vehicle built to Euro 6 standards.

Today Euro 6 is a common system on all types of passenger cars, light commercial vehicles and heavy vehicles.

However, the AdBlue system often causes problems on Euro 6 vehicles. This leads to financial loss for users and, because repairs take a long time, loss of time.

When a fault occurs in the AdBlue system, the vehicle protects itself and limits speed to 20 km/h. Fuel consumption also increases because of this fault.

At this point users try some solutions while waiting to reach a repair centre.

Two solutions used in these situations are;

• Using an AdBlue emulator
• Disabling the AdBlue system from the ECU

What Are the Disadvantages of AdBlue Disable From the ECU? How Does It Work?

IMPORTANT NOTE: First, when you have your vehicle's AdBlue system disabled from the ECU, your vehicle reverts to Euro 4 standards.

Your vehicle's fuel consumption will increase by at least 3 points.

This is the primary damage from ECU-based AdBlue disable.

You can easily confirm this fuel increase with tests. You cannot benefit from any savings system brought by Euro 6 norms. In short, you lose while trying to save.

Disabling AdBlue from the engine control unit works by downloading the software from your vehicle's ECU to a computer, bypassing AdBlue-related lines in the software and reloading it to the vehicle.

After this process the software in the engine ECU is changed and dynamic differences arise between it and the original software.

After ECU-based AdBlue disable, your vehicle behaves as if it has no AdBlue system software.

However, the physically present AdBlue system (DPF, SCR filters, etc.) continues to function.

Because the software no longer has an AdBlue system, these physical units are not cleaned by regeneration.

Therefore these units must be removed. The vehicle cannot be restored.

In short, after this process your vehicle can neither physically nor in software return to its original state. It loses Euro 6 compliance.

Why Should I Use an Emulator?

• AdBlue disable via emulator is done by connecting a device to the vehicle CAN bus with two cables.
• After this process your vehicle behaves as if the AdBlue system is present and continues on the road unchanged from its original state.
• Nothing changes in your vehicle software.
• Your vehicle detects DPF and SCR fill levels as with a normal AdBlue system and performs regeneration.
• You do not need to remove the DPF and SCR system.
• After removing the emulator your vehicle instantly returns to its original state. This takes less than one minute.
• You can restore your vehicle whenever you wish.
• Your vehicle keeps Euro 6 compliance and continues to operate to Euro 6 standards after faults are fixed.
