Volvo FH, FE, FM, FMX, FL we have the right solutions. D6K, D8K, D11K, D13K and D16K engines
NEW VOLVO FH4 EURO 6 - EGR FAP SCR OFF AND POWER
Solutions for all models
We've recently developed our own engine tune-ups, and found a way to disable the EGR FAP and AdBLUE systems on Euro 6 Volvos from 2014 to today. We give you more details just below.
On all Euro 6 Volvos equipped with ACM 2.1 Continental and EMS 2.3 and 2.4 TRW ECUs we now have new, reliable, stable and tested solutions. We offer you the possibility of eliminating EGR - FAP - ADBLUE - as well as improving vehicle performance.
The operation consists of working at the heart of the ECU, directly in the vehicle's original program, in both the engine management and post-processing units.
We need to have the truck under cover for this customized programming. Intervention time per vehicle is around 3 hours, and sometimes longer, depending on where the ACM is located (hard-to-reach places on 6x4 8x4 tippers, rigids, etc.). Tractor-trailers are easier to access. It's also possible to send us the Engine Management Module and ACM pair, so we can operate without needing the vehicle.
The operations you'll read about below still apply (via OBD plug if possible, or via Limp Off box), but we now recommend opting for the solution we've just detailed, as it's also the only way to remove the EGR valve and increase power to lower fuel consumption.
We support all Volvo Euro 6 FM FMX FL FH4 FH16 models from 2014 to today, regardless of engine size, as long as the vehicles are equipped with the modules described above.
What models can we work on?
Basic operation and problem parts
The engines affected by AdBlue malfunctions on Volvo Euro 6 trucks are mainly the D6K, D8K, D11K, D13K and D16K. The exhaust gas treatment system closely links the following elements: Engine Management Unit (ECU) and Aftertreatment Control Module (ACM) to the particulate filter and AdBlue system. Here's a diagram of the Euro 6 system fitted to Volvo trucks
7th injector
A specific diesel injector is used for thermal management of the diesel oxidation catalyst. It also ensures the efficiency of the diesel particulate filter and the smooth operation of the SCR system.
DOC catalyst
DOC produces the nitrogen dioxide (NO2) necessary for the diesel particulate filter particulate matter. At very temperatures, it also provides the heat required for regeneration.
FAP / DPF
The filter captures and stores particles until they are burnt off during regeneration. Regeneration takes place automatically, so the driver doesn't nothing to do.
SCR & ASC
In the mixing zone, the exhaust are sprayed with AdBlue. When they reach the catalytic converter, nitrogen oxides (NOX) are converted into neutral nitrogen and and water. The ASC catalytic converter is the last stage before the exhaust pipe. This is where any remaining ammonia (NH3) is eliminated.
Torque reduction, Speed limited to 20km/h
The 20km/h speed limit and torque reduction are very restrictive for the driver. It is no longer possible to drive the truck without endangering road traffic. This fault code can only be cleared once the problem has been solved. In 90% of cases, this restriction is linked to a malfunction in the vehicle's emission treatment system. Find out what causes this restriction below.
AdBlue system faults can come from a variety of sources.

2 choices: Emulator or ECU programming
Limp Mode - A creeping mode that limits you to 20kmh
Limp mode is one of the most restrictive modes, restricting you to a speed of 20kmh when your emission control system is faulty. Our box allows you to shut down the ADBLUE FAP system and REMOVE ALL LIMITATIONS in the ECU. The box connects directly in place of the original ACM. (See video below.)
Programmable deactivation
Everything is done electronically. No additional components are connected to the vehicle. We proceed by completely reprogramming the AdBlue system via the engine ECU, connecting to the truck's diagnostic socket (OBD2).
REQUIREMENTS & PREREQUISITES
The box below is the engine management unit or ECU. We intervene in the ECU's memory to remove fault codes and permanently disable the system on your vehicle.
Emulation deactivation
The operation involves adding an AdBlue system virtualization module by connecting a box to the ACM ECU. The operation is simple, and the box can be sent anywhere in the world. Moulded box on original Volvo connector.

Here's our emulator, designed with the vehicle's original connector in mind, for easy installation! Unplug the original ACM harness and connect it to our module.
YOU DON'T WANT TO REMOVE YOUR ADBLUE DEVICE?
We understand that you don't want to inhibit your AdBlue device, and that's perfectly legitimate. Firstly, to protect the planet, and secondly, simply to comply with legislation. However, you also don't want to be stuck on the side of the road, in power reduction mode, with no solution other than to call the breakdown mechanic and end up with a high bill, both for the breakdown service itself and for the intervention on your AdBlue system at the dealership, which is often in the region of €3,000, and that's understandable.
On which models can you take action without eliminating Adblue?
In the majority of cases, messages such as "power reduction in 8h", "power reduction in 4h", "power reduction in 2h" or "power reduction at next start" are due to a fault in your truck's anti-pollution system. Very common on 11L D11K engines, and even more so on 13L engines (D13K 420, 460, 500 and 540) powering Volvo FH 420, FH 460, FH 500 and FH 540, as well as a few cases encountered on Volvo FH16, which are a little rarer because they benefit from a slightly different management of the gas recycling program. These faults are also present on Renault commercial vehicles which have borrowed the engine from the Nordic manufacturer. We're talking here about recurring problems on Renault T models (T440, T460, T480, T500 and T520), of course under the Euro 6 standard.

Cause of 20km/h limit and fault P207F9A - Poor AdBlue quality
The truck's anti-pollution system is faulty, and will restrict the vehicle by implementing a program in the ECU to run the truck in degraded mode, totally limiting its traction force (torque), as well as its maximum speed to 20kmh, meaning that the vehicle is unusable.
The problem arises mainly when the Adblue device is faulty (problem with the Adblue injector or pump), which results in faulty Adblue metering, and thus in the engine management module detecting poor Adblue quality. It often appears that the particle filter is faulty and needs to be replaced, depending on the fault code and message. This can be confusing, as a message on your truck's dashboard indicating a fault in Adblue quality is in fact, in the various cases we've encountered, linked to an overloaded particulate filter or a fault present on it.
How do I get out of the 20km/h limit?
Immediately remove the defect to regain power! How do I do it?
Theoretically, only the dealer or a garage equipped with the manufacturer's diagnostic kit is able to clear faults. However, symptoms can reappear very quickly - a few hours after deletion, or even after driving a few kilometers, sometimes less than ten.
In response to increasing demand, we have developed a process for automatically eliminating the fault before the vehicle is started. Digiservices Normandie now makes it possible to eliminate power reduction on heavy goods vehicles. Our mini-case emulates part of the manufacturer's case when the technician initiates the procedure to clear the engine light, so that the truck regains its original power and engine torque. The process is very simple, and we've developed the system to suit all types of driver, from 18 to 65 (and beyond 🙂 ). The system is as simple as plugging into a 220V electrical outlet. No knowledge, hardware or diagnostics are required. Simply connect our system to the truck's OBD socket and our intelligent programmer will do the work for you, just as if you were at the dealership.
10s, Connect it's erased! Plug in, switch on, wait for automatic process, unplug, switch off and START!
This is a cost-saving alternative that avoids having to secure the truck (breakdown service, immobilization, waiting for a manufacturer's appointment...). A thorough diagnosis at the dealership (or with us in Normandy) is necessarily useful to pinpoint the exact origin of the problem, although the items listed above are the most common. On the other hand, driving tens of thousands of kilometers with a defective component on the truck is not an option. We know what to do in most cases, and have the right solutions for your fleet.
