Neutralizing the aftertreatment system (i.e. removing the Adblue Deutz Fahr) initially involves disabling Adblue operation on the vehicle. DEF (Diesel Exhaust Fluid) consumption is stopped, and various components such as the pump, NOx sensors and adblue injector can be disconnected.

Deutz engines are also equipped with particle filters, which filter out micro-particles. Located just after the catalytic converter, the particle filter gradually becomes clogged with soot produced by the engine. As it fills up, it tends to impair engine operation, and a regeneration process (burning off the soot) becomes essential. After a while, when the soot level is higher than normal, the problems begin: regeneration is impossible because the soot level is too high, and the vehicle is put into degraded mode, restricting tractor or machine performance. It's an option to be added to the SCR system according to your needs. It's costly, but still less than if you had to replace the entire exhaust system.

The EGR valve allows exhaust gases to be recirculated into the intake system to be burned a second time. Although this function reduces air pollution, it actually increases it in your engine. In fact, this anti-mechanical element sends the unburnt particles back into the intake to burn them a second time... As a result, you're sending dirty gases back into the intake, even though we're told that, for best performance, the air must contain as many oxygen molecules as possible... Neutralizing this valve prevents your Deutz engine and Deutz Fahr machine from clogging the intake ducts. The valve can be physically disconnected and sealed with a metal plate to prevent the passage of gas.

Deletion of the anti-pollution device on Deutz Fahr machines is carried out directly in the EMR engine management unit. The EMR memory is saved beforehand (in case you need to go back). We connect either via the manufacturer's diagnostic socket, or by the bench method directly to the engine ECU pinout. We do not open the box. The programmed operating data can be used to :

Mercedes engines operate somewhat differently from Deutz engines. Exhaust after-treatment is performed by two modules connected together via the CAN BUS network. These are the MCM (Motor Control Module) and the ACM (After Treatment Contol Module). Since the signals from these two units are transmitted via the vehicle's communication network, it is necessary to modify the data in both ECUs.

We know that it's not easy to bring your tractor or harvester to us so that we can find the solution you need. That's why we offer our service all over France, and even further afield, as we travel all over Europe and sometimes even to non-EU countries. Don't hesitate to contact us if you're having Adblue problems with your Deutz Fahr machine and can't find a solution. We're sure to have a solution for you.
