Removing AdBlue Renault Euro 6 Trucks Model T K C D

T, C, K, D Series, We do have solutions for engines from 5 to 13L displacement.

Basic operations and problematic parts

When AdBlue incidents occur on Renault Trucks vehicles, it becomes completely impossible to use it. Loss of more than 80% of power, torque limitation and maximum authorized speed of 20Km / h. We will offer you several solutions to counter these faults. First of all, let's take note of the vehicles on which our solutions can be adapted.

Renault T, C, K and D use Volvo Trucks engine, so our solutions adapt to both brands.

Principe de fonctionnement du système de traitement des gaz / AdBlue sur Renault Trucks

7th injector

A specifical injector used for catalyst thermical diesel oxydation. It assures DPF efficiently and SCR proper functioning.

Catalyseur DOC

The DOC produces the NO2 necessary for the DPF to efficiently combust the particulates. In cold conditions, it also provides the heat needed for regeneration.

FAP / DPF

The filter collects particulate matter (PM) and stores it until it's burned off during regeneration

SCR & ASC

In the mixing zone, the exhausts are sprayed with AdBlue. When they reach the catalyst, the nitrogen oxides (NOx) are efficiently transformed into harmless nitrogen gas and water.

Torque reduction and speed limitation to 20km/h

What are the elements that cause these troubles...?

What cause a failure in After Treatment Gaz Management ?

  • Dashboard fault code and check engine light
  • Dashboard displays a message saying that the trucks is going to enter in torque reduction in xxx hours, or at the next starting.
  • Speed limit is automatically set to 20Km/h
  • The truck display a message related to bad AdBlue quality with the P207F9A trouble code.

Probable causes :

  • 7th injector : Seized or broken. There is no more Adblue injection into the Adblue system.
  • DOC System : Burnt, broken or molten. Does not permit anymore a proper functioning of the gas post treatment and can in the long run, clog the DPF because no more regeneration are available.
  • DPF : Can be clogged. Too many short trips and regeneration cannot be performed because exhaust gas temperature are too low. The P207F9A is often displayed when a DPF problem is present.
  • SCR & ASC : SCR catalyst clogged or destroyed. Defective NOx sensors

2 process : Virtualizing by emulator or directly in ECU 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

  • Step 1: The current version of the engine control unit must correspond to a version that we can program. A version of Software calculator too recent does not allow us to intervene because we would not have the coding keys to validate the programming. To find out if your vehicle is eligible, you can contact us by providing the vehicle serial number. Our privileged access to the internal Volvo / Mack / Renault database allows us to know in real time the latest updates made.
  • Step 2: The vehicle can be equipped with the VEB retarder and hydraulic retarder taken from the gearbox. No restrictions on this.
  • Step 3: You can come to our workshop to carry out the operation if the previous conditions are met. We will connect via the OBD2 port of your Volvo Euro 6 truck to operate. If you are not located geographically close to our garage (near Rouen), we can operate remotely. To do this, we will have to send you our PC equipped with the required software and hardware against deposit. Once connected to the Internet, we will take remote control to carry out the operation. All you have to do is switch on and off when requested.
  • Step 4: Once the operation is completed, you will no longer have any fault codes relating to the AdBlue system. Everything will be electronically deleted from memory and permanently.
  • Step 5: It is very important to take note of this recommendation. Any vehicle updated at a Volvo dealership will be deleted from our schedule. The manufacturer update will be too recent for us to perform the deletion operation again. As mentioned in step 1, if your software version was eligible for programming IT WILL NO LONGER BE IT and you will lose our program and your investment in our solution. We cannot be held responsible for dealer update operations. Please specify this to the workshop foreman if you know him or to the competent personnel, if necessary avoid visits to the manufacturer.

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.

266/5000 On vehicles fitted with the "Voith Hydraulic retarder" in direct connection to the transmission, it is not possible to mount an emulator on pain of displaying numerous ABS braking faults, line crossing, emergency automatic braking failing.

MANDATORY CONDITIONS & PREREQUISITES

  • Step 1: It is essential for this operation via emulator, that the vehicle is not equipped with the retarder on the gearbox. VEB OK, but not hydraulic delay, only the retarder on exhaust.
  • Step 2: No restriction of the software version of the vehicle. Recently released trucks can be modified.
  • Step 3: The intervention can be done in our workshop for half a day. If necessary we have the possibility to send our box all over the world. Very little knowledge is required for assembly. We designed our box with an original connection of the vehicle then inserted our own integrated circuit inside. It is therefore easy and quick to set up and the margin of error is very small.
  • Step 4: In the majority of cases the defect will be automatically erased but we have already had cases where an erasure of faults in the suitcase is compulsory after installation. Once done, you can drive without worrying about running out of AdBlue.
  • Step 5: The vehicle can go to the dealership and benefit from an update without the risk of erasing the internal memory of our unit. The case is IP68, that is to say which resists water in the proportions provided by the standard IP68.
  • CAUTION: You will find on the internet many copies of our box that do not work and sold at half price. Play the security card.
  • Our emulator acts on the parameters and inhibits the following peripherals AdBlue PUMP, NOX SENSOR, CATALYST, TEMPERATURE SENSOR, ADBLUE INJECTOR, ADBLUE TANK LEVEL.

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.

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.

Sur quels modèles agir sans supprimer l'Adblue ?

We have detailed above all the models on which we can intervene definitively. We can also offer you an alternative and less costly solution via OBD which will allow you to erase the faults yourself until time to resolve the problem. Some of our customers have even used this method for many months before doing anything on their truck.

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 truck's OBD socket and our smart 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 !!

597/5000 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.
