Volvo/Renault Version 4 SCR delete tuning solution.
When is the service needed?
If the cost of fixing your truck’s or bus’s emission systems is getting too expensive, our remote tuning service may be the perfect solution.
Derates, loss of power, poor fuel economy, and costly downtime that keep your truck or bus off the road are often caused by a failing SCR system.
Our remote tuning service solves these problems by professionally deleting the SCR system through ECU software reprogramming. This eliminates some of the most common emissions-related failures and significantly lowers the ongoing maintenance costs associated with factory emission equipment.
And if you’d rather get ahead of the problem before it starts, this service is for you too. Proactively removing the SCR system before it fails meanфs you’ll never have to deal with those expensive repair bills in the first place. Once tuned, your truck or bus will run without SCR-related errors or performance loss caused by system restrictions. The result is a more dependable vehicle with less downtime and fewer disruptions.

Guides & Instructions
Tuning results
- No SCR fault codes
- No torque reduction
- No warning lamps on the dashboard
- Minimal intervention into current ECU Calibration. We know what we do. No one unrelated parameter will be changed
- 3 or 4 SCR — related ECUs are reprogrammed together
Required hardware changes after tuning
ATTENTION!
After applying our SCR delete service:
- ACM (Aftertreatment Control Module) and both NOx sensors must remain unplugged indefinitely! Plugging them back in will cause a “soot level high” message and immediate engine derate!
Exception: on EU trucks equipped with a transmission brake, the ACM must remain connected, but the Engine CAN wires (pins 1 and 5 in the ACM connector) must be cut off.
- We strongly recommend bypassing the SCR cans or removing them

Additional Information
It’s a remote ECU reprogramming done through the OBD socket that disables the SCR (AdBlue/DEF) system. In simple terms, the engine is set up to run without relying on DEF dosing or NOx feedback.
This Volvo / Renault Euro 5 SCR delete (OBD socket) service is a remote ECU programming aimed at one thing: getting rid of the constant headaches tied to the AdBlue/DEF system. If you’ve dealt with dosing faults, NOx sensor errors, or random warnings that lead to derates, you already know how disruptive it can be.
On Euro 5 platforms, the SCR system is tightly linked to engine operation. Over time, components like DEF pumps, injectors, and NOx sensors start to wear out. What begins as an occasional warning can quickly turn into repeated fault codes, limited power, or even a truck that refuses to work when you need it most.
Instead of chasing those issues one by one, we retune the ECU through the OBD port so the engine no longer depends on SCR inputs. No pulling the ECU apart—just a clean, controlled update using professional tools and a secure remote session.
Once it’s done, the truck typically behaves in a much more predictable way. No more DEF quality messages, no surprise derates from SCR faults, and far fewer interruptions during daily operation. It’s a practical solution for operators who prioritize uptime, especially in long-haul or fleet environments.
If you want, we can also include a mild performance upgrade during the same session.
Key Benefits:
- OBD-based SCR (AdBlue/DEF) delete for Volvo and Renault Euro 5 vehicles
- Eliminates common DEF system faults and NOx sensor issues
- Prevents SCR-related derates and power limitations
- No need to remove or open the ECU (OBD socket programming)
- More stable and predictable engine behavior in daily use
- Reduces downtime caused by emissions system failures
- Suitable for trucks and buses in commercial and fleet operation
