MAN AdBlue OFF Service / MAN Truck SCR Removal Software

MAN trucks use an AdBlue (SCR) system to reduce emissions, but this system can lead to high maintenance costs and frequent failures. Many truck owners opt for AdBlue OFF by modifying the ECU software. This guide explains the AdBlue deactivation process, its benefits, and the required modifications for MAN trucks.

MAN Truck ECU Programming Process for AdBlue Deactivation:

Disabling AdBlue in MAN trucks involves several key steps:
1.    Reading the ECU Data: Utilize specialized tools like KESS3 or KTAG to extract the original software from the ECU.
2.    Modifying the Software: Adjust the ECU parameters to deactivate the AdBlue functionality. Given the complexity and variability among ECUs, it's essential to use the original A2L/Damos files to accurately locate and modify relevant values. Unlike standard parameters such as Spark Advance or Boost Pressure, AdBlue deactivation requires specific solutions tailored to each ECU type.
3.    Flashing the ECU: Write the modified software back to the ECU, effectively disabling the AdBlue system.
4.    Testing and Verification: Conduct thorough testing to ensure the vehicle operates correctly without triggering warning lights or entering limp mode.

What is  MAN ACM and is it necessary to modify the ACM for AdBlue OFF?

MAN trucks are equipped with an Aftertreatment Control Module (ACM), which works alongside the ECU to manage the Selective Catalytic Reduction (SCR) system. The ACM used in MAN Euro 6 trucks is typically the Temic ACM2.1 or ACM2.2.
However, when performing an AdBlue OFF (SCR OFF) solution, there is no need to modify or read the ACM. The entire AdBlue deactivation process can be completed solely by remapping the ECU, such as Bosch EDC17CV41, EDC17CV42, or MD1CE100. By carefully adjusting the ECU software, our AdBlue delete solution ensures that the system is fully disabled without triggering errors, limp mode, or check engine lights. This method provides a safe, effective, and hassle-free solution for MAN truck owners looking to eliminate SCR-related issues.

Best Programming Tools for MAN Truck ECUs 

To successfully program MAN truck ECUs, a variety of advanced tuning tools can be used. The most commonly used tools include:

•    KESS3 –  A versatile OBD and bench programming tool for reading and writing ECU data efficiently.
•    Trasdata –  A powerful boot mode programmer ideal for advanced modifications and unlocking ECUs.
•    Autotuner –  A fast and user-friendly ECU tuning tool that supports both bench and boot modes for MAN ECUs.

These tools allow direct access to ECUs such as Bosch EDC17CV41, EDC17CV42, and MD1CE100, enabling AdBlue OFF (SCR OFF), DPF OFF, and other performance tuning modifications.

How to Program a MAN Truck ECU (EDC17CV42)

Step 1: Gather Necessary Equipment

• Programming tool (KESS3, Trasdata, or Autotuner with GPT support)
• OBD/GPT connection cables
• Stable power supply (12V/3A recommended)
• Laptop with tuning software (WinOLS, Swiftec, ECM Titanium, etc.)

Step 2: Connect to the ECU Using GPT Pinout

• Use the KESS3, Trasdata, or Autotuner GPT pinout diagram to correctly connect the tool to the ECU.
• Ensure GPT, CAN-H, CAN-L, and power lines are properly connected.
• No need to ground a boot pin—GPT automatically handles secure ECU unlocking.

Step 3: Read the ECU Data

• Open your tuning software (KESS3, Trasdata, Autotuner).
• Select Bosch EDC17CV42 from the ECU list.
• Choose “Read” to extract the original ECU data without opening or removing the ECU.
• Save a backup of the original file for safety.

Step 4: Modify the ECU File

• Open the read file in WinOLS, Swiftec, or ECM Titanium.
• Apply necessary modifications such as:
  • AdBlue OFF (SCR OFF)
  • DPF OFF
  • EGR OFF
  • Performance tuning for power or fuel efficiency

Step 5: Write the Modified File Back to the ECU

• Load the modified ECU file into your programming tool.
• Select “Write” and confirm the flashing process.
• Ensure the process completes without interruptions or errors.

Step 6: Verification & Testing

• After writing the modified file, restart the vehicle.
• Check for any error codes, limp mode issues, or check engine lights.
• Perform a test drive to confirm proper engine performance and smooth operation.

By following this method, you can efficiently program MAN EDC17CV42 ECUs for AdBlue OFF, DPF OFF.

Is there any check engine lights and DTC after MAN AdBlue removal?

A properly executed AdBlue delete should also address related Diagnostic Trouble Codes (DTCs) to prevent warning lights and limp mode activation. Common codes removed include:

• P20E8 – Reductant pressure too low
• P207F – Reductant quality performance
• P204F – Reductant system efficiency
• P203B – Reductant level sensor circuit
• P20EE – SCR NOx Catalyst Efficiency Below Threshold
• P229F – NOx Sensor Signal Out of Range
• P2BA9 – Incorrect DEF Detected
• P204C – Reductant Temperature Sensor Circuit
• P2200 – NOx Sensor Circuit Malfunction
• P2047 – Reductant Injector Circuit

By ensuring that all related DTC codes are properly disabled, the vehicle will function normally without triggering check engine lights.

Is AdBlue Deactivation Legal for MAN Truck?

It is important to consider the legal implications of disabling the AdBlue system. Many countries have strict emissions regulations, and tampering with emissions control systems may result in fines or penalties. This modification is recommended for off-road or export vehicles where emissions compliance is not a concern. Truck owners should consult local regulations before proceeding with AdBlue OFF solutions.

Conclusion

ECU remapping for AdBlue deactivation is a practical solution for MAN trucks facing frequent SCR system failures and high AdBlue costs. By modifying the ECU software, truck owners can eliminate the need for AdBlue while ensuring optimal vehicle performance. However, legal considerations must be taken into account before implementing this solution.
For professional AdBlue OFF tuning and ECU remapping, always seek experienced technicians to guarantee safe and efficient modifications.
