Volvo Euro 6 : Solutions to Adblue Issues
Volvo FH, FE, FM, FMX, FL we have the right solutions. D5K, D8K, D11K, D13K and D16K engine
All supported models Euro 6
Many models are affected by Adblue system failures, more commonly on models FH420-FH460-FH500-FH540 but also on models in the FL, FM, FE, and FMX range
For which models we have solutions?
Basic operation and problematic 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 (ECU) and ACM calculator (Aftertreatment Control Module) to the particulate filter as well as to the AdBlue system. Here is a diagram representing the Euro 6 device equipping Volvo trucks
7th injector
A specific diesel injector is used to thermal management of the diesel oxidation catalyst. It also guarantees the efficiency of the diesel particulate filter and the proper functioning of the SCR system.
DOC catalyst
DOC produces nitrogen dioxide (NO2) necessary for the diesel particulate filter for effectively burn particles. A very at low temperatures, it also provides the heat required for regeneration.
FAP / DPF
The filter captures and stores the particles until they burn during regeneration. Regeneration takes place automatically so that the driver has nothing to do.
SCR & ASC
In the mixing zone, the exhausts are sprayed with AdBlue. When they reach the catalyst, nitrogen oxides (NOX) transform into neutral nitrogen and in water. The ASC catalyst is the last step before the exhaust. This is where any remaining ammonia (NH3) is removed.
Torque reduction and speed limitation to 20km/h
Limiting the speed to 20km / h and reducing the torque are very restrictive for the driver. Indeed it is no longer possible to travel with the truck without endangering road traffic. This fault code can only be erased after having resolved your fault. In 90% of cases this limitation is linked to a malfunction of the vehicle's pollutant emission treatment system. Find out what is causing this restriction below.
AdBlue system faults can come from different sources.

2 choices: Emulator or Computer programming
Deactivation by programming
Everything happens via electronics. No additional elements are connected to the vehicle. We proceed by complete reprogramming of the AdBlue system via the engine ECU by connecting to the diagnostic socket on the truck (OBD2).
MANDATORY CONDITIONS & PREREQUISITES
The box below is the engine management box or ECU. We intervene in the memory of this software to delete the fault codes and deactivate the system permanently on your vehicle.
Deactivation by emulation
The operation is done by adding a virtualization module of the AdBlue system by connecting a box to the ACM computer. The operation is simple and the box can be sent worldwide. Housing molded on Volvo original connector.
MANDATORY CONDITIONS & PREREQUISITES
The box below is the engin control unit or ECU. We intervene in the memory of this software to delete the fault codes and deactivate the system permanently on your vehicle.
Below, our emulator, exactly designed with the original connector of the vehicle for easy mounting! Disconnect the harness connecting the original ACM and connect it to our module.
DON'T WANT TO DELETE YOUR ADBLUE DEVICE?
We are aware that you do not want to inhibit your AdBlue device and this is completely legitimate. One to protect the planet and two simply to comply with the law. However, you also do not want to be blocked on the side of the road, in power reduction mode without any solution other than to call the convenience store and end up with a high bill, both by the repair itself and by the intervention on your AdBlue system in dealerships, which is often around 3000 € and that is understandable.
On which models to act without removing the Adblue?
In the majority of cases the messages of power reduction in 8h, power reduction in 4h or even power reduction in 2h or power reduction at next start-up comes from a fault present in the emission control system of your truck. Very common on 11L D11K engines, and even more on those of 13L (D13K 420, 460, 500 and 540 engines) fitted to Volvo FH 420, FH 460, FH 500 and FH 540 as well as some cases encountered on Volvo FH16 , a little rarer because they benefit from a slightly different management of the gas recycling program. These faults are also present on Renault industrial vehicles which borrowed the engine from the Nordic manufacturer. We are talking about recurring problems here on Renault T (T440, T460, T480, T500 and T520), of course under the Euro 6 standard. All the models above FM FE FH FL FMX...
Cause of the 20km / h limitation and fault P207F9A - Poor AdBlue quality
The truck's antipollution system is faulty, and will restrict the vehicle via the implementation in the computer of a program operating the truck in degraded mode, completely limiting the traction force (torque), but also its maximum speed at 20kmh , as much to say that the vehicle is unusable.
The problem mainly arises when the Adblue device is defective. (problem on the Adblue injector or pump) this therefore produces a dosing defect in the Adblue which therefore does not respect the quantities provided by the engine management module and therefore detects poor Adblue quality. It often appears that the particle filter is defective and requires replacing the cartridge according to the fault code you have and the message. This can be confusing, because a message on the dashboard of your truck indicating a defect in the quality of Adblue is actually, in the various cases that we have encountered, linked to an overload of the particle filter or a defect present. on this one.
How to self-repair and get out of the 20km / h limit?
Clear the fault immediately to regain power! How? 'Or' What ?
Theoretically only the dealer or a garage equipped with the manufacturer's diagnostic case is able to erase faults. However, symptoms can recur very quickly; a few hours after erasure, or after having driven a few kilometers, sometimes less than ten.
Following the upsurge in demand, we have developed a process for self-elimination of the fault before starting the vehicle. Suppressing the reduction of power on heavy goods vehicles is now possible with Digiservices Normandie. Our mini suitcase partly emulates that of the manufacturer when the technician launches the engine light erasure procedure, so the truck regains its original power as well as its engine torque. The process is very simple, we have developed this system so that it adapts to all types of driver, from 18 to 65 years old (and even more 🙂 ). The system is as simple as plugging in a 220V electrical outlet. No knowledge, hardware or diagnosis is required. Simply connect our system to the OBD socket on the truck and our intelligent programmer will do the work for you as if you were in a dealership.
10s, Connect is deleted! Plug in, Switch on the ignition, Wait for the automatic process, Unplug, Switch off the ignition and START !
This solution is an alternative making it possible to make big savings by avoiding the safety of the truck. (troubleshooting, immobilization, waiting for an appointment with the manufacturer, etc.) An in-depth diagnosis in dealerships (or with us in Normandy) is necessarily useful for diagnosing the exact origin of the problem, although the elements mentioned above are the most common. On the other hand, traveling tens of thousands of kilometers with a defective element on the truck is prohibited. We know how to act in most cases and have troubleshooting solutions for your fleet.
