Adblue emulators are mainly used in trucks and other heavy vehicles, although we are seeing adblue emulators for light vehicles/cars and vans also emerging. The main purpose of adblue emulator is to replicate normal SCR system performance. It does that by sending signals to the vehicle’s ECU indicating that everything within the SCR/NOX systems is working fine, even though the SCR system is disconnected or removed altogether.

Adblue emulator will require power supply and also connection to CAN lines. Installation on Euro 6 trucks may be a little more complicated. The emulator is normally connected to after ignition power supply so that it becomes operational once ignition is turned on, and goes off once ignition is turned off. Adblue emulator will send signals via CAN lines to the truck’s ECU (engine control unit) imitating normal SRC system performance this way fooling the ECU in to thinking everything within the SCR/NOX systems is working as should be. ECU no longer detects any defects/faults within the SCR system as it is no longer receiving such data from the SCR system, instead the signals come from the emulator. You will also need to disconnect SCR system after installing adblue emulator, this is normally done by removing fuses or cutting power supply. SCR system will no longer be operational and no DEF/adblue will be used. 

With good quality adblue emulator, after installation there should be no warning lights on your dashboard, adblue level gauge should be operational and everything should look and feel as normal, as if nothing happened.. 

SCR system can be restored back to working order by simply removing/disconnecting the emulator and restoring the power supply to the SCR system. Normally, there will be no damage to any SCR system components after restoring it to normal performance after the adblue emulator was used, but there are some exceptions. Without the adblue fluid circulating through the SCR system, some of its components may fail after some time. For example, on some trucks adblue pump is also cooled with adblue liquid, hence when the SCR system is disconnected / not working and no adblue liquid is flowing through, it may cause for the tump to fail/cease. In trucks where such risk exists a proper adblue emulator installation would be to remove the pump and block off any openings this creates. We are well familiar with such risks and issues that may arise in the future so please get in touch and we will advice you what is needed to successfully install/use adblue emulators in your trucks.

Euro 5 trucks would normally be equipped with SCR (adblue) system as well as one or two nox sensors, depending on vehicle make and model. Can Smart adblue emulators do emulate SCR system in full as well as nox sensor(s). This means they will solve any SCR or NOx related problem. Another great thing about our adblue emulators is that you can install them even if your truck is already showing SCR or NOx related error codes and, furthermore, you can even install it to a truck, which is in limp mode/limp home mode. There will be no need for diagnostic tools to clear the faults; our Euro 5 adblue emulator will make error codes, warning lights and limp mode disappear after installation!

Euro 6 trucks would have more complicated emission systems. These would normally consist of SCR system, DPF and two nox sensors. Unlike with Euro 5 adblue emulators, there are no universal emulators available for Euro 6 trucks. These vehicles will require a dedicated emulator and will also incur a little more complicated installation. Normally, to install adblue emulator to Euro 6 truck you will need to connect anywhere between 4 and 12 wires, depending on vehicle make and model. Most Can Smart adblue emulators for Euro 6 trucks will emulate all emission systems, (SCR, DPF, NOX) but that depends on vehicle make and model. Some will emulate everything, others may only emulate SCR system, etc.. Please make sure to ask these questions when purchasing adblue emulator to make sure you are getting precisely what you need.

Can Smart adblue emulator range for EURO 6 trucks:









We may also be able to offer solutions for other heavy goods transport such as agricultural or construction vehicles. Please get in touch to confirm possibilities.

Volvo trucks are well known for their SCR, NOX and DPF systems being very unreliable. Another grim fact is that Volvo adblue system problems are very expensive to fix. Naturally, many Volvo truck/fleet owners would rather have these systems ‘put to sleep’ instead of constantly spending vast amounts of money to repair these Volvo SCR or DPF systems. Although, adblue emulators are illegal in the UK and within the EU, there are plenty countries out there that do not enforce/support European Emission Standards and where using adblue emulator is perfectly legal.

Lets discuss Volvo Euro 5 trucks first. Most common Volvo Euro 5 truck models are: FH, FM, FMX, FE, FL. All of these models have the same SCR system hence the same Volvo Euro 5 adblue emulator will be suitable for all of them. These trucks would also have two nox sensors in addition to SCR system. Can Smart emulators will disconnect and fully emulate both. adblue system as well as nox sensors. Cheaper Chinese or Turkish versions will normally disconnect only limited components within the Volvo SCR or Nox system. To install the emulator in Volvo Euro 5 trucks you will need to connect four wires, installation should not take more than 20-30 minutes. After installing Can Smart emulator your adblue level gauge and all other parameters will be indicating normal SCR and Nox system performance. Even if the vehicle already had adblue or nox errors/faults prior to installing the emulator, these will disappear. If your vehicle was in limp mode it will be back to full power after installing Can Smart adblue emulator.

Plug & play Volvo euro 5 adblue emulators are also available on request. Such emulator would plug into SCR socket located within the junction box under the bonnet. You would also need to connect single wire (negative) This would save you about 10 – 15 minutes on installation, but apart from that it offers the same benefits as the emulator which has to be hardwired in.

It may also be possible to disconnect adblue and nox on Volvo euro 5 trucks by re-mapping the ecu file. This would involve changing factory settings (maps) within the ECU file. A file needs to be downloaded and emailed to us. Once we have modified it, we will send it back for uploading.

Next we have Series 4, Euro 5 Volvo trucks. These trucks are normally known as FH4, FM4… It is important to understand that these trucks are different to Series 3 Euro 5 models. Volvo 4-series Euro 5 trucks will require a special, dedicated adblue emulator as normal Euro 5 emulator will not be suitable. 4-series trucks have a different emission control system to that of an older, 3-series Volvo trucks. Can Smart adblue emulators for Volvo FH4 Euro 5 trucks are one of the best out there and suitable for trucks with retarder or without. We can also offer plug&play adblue emulator for Volvo FH4 Euro 5 trucks.

Volvo FH4 Euro 5 adblue emulator is the only option available at present to disconnect adblue system. ECU file re-mapping is not possible on these models.

Volvo Euro 6 trucks have completely different, and way more advanced emission control systems. There are no universal emulator which would fit all models. There are two types of SCR systems in Volvo Euro 6 trucks, one in large lorries such as FH, FM and another, slightly different system in small, town trucks such as FE, FL. We can offer adblue emulators all of these models. For Volvo FH, FM, FMX trucks we can offer a choice of adblue emulators, Can Smart Volvo Euro 6 adblue emulator (this has to be wired in) or Can Smart Plug & Play adblue emulator. Apart from the installation, the only other difference is that plug & play adblue emulator is only suitable for trucks without retarder. Normal Volvo Euro 6 adblue emulator is suitable for trucks with retarder or without.

Volvo Euro 6 adblue emulator is the only option available at present to disconnect adblue system. ECU file re-mapping is not possible on these trucks.

Adblue emulator installation depends on factors such as vehicle make, model euro emission standard and emulator make. Most commonly, there will be 4 wires to connect, these would be positive, negative, can hi and can lo lines. Normally, the same emulator would be suitable for euro 4 and euro 5 standard trucks, euro 6 trucks would need a different emulator as euro 6 standard emission systems are way more complicated. Adblue emulator installation to euro 4 and euro 5 trucks is normally quite simple and straightforward. Installation of Can Smart emulator for trucks like DAF, MAN, VOLVO, RENAULT, IVECO is very easy and you will not need to do anything else, simply connect the emulator and you are done. Emulators for these vehicles will have four wires to connect and you will also need to disable adblue and nox system after installation, this way letting the emulator to take over. SCR system disconnection can be done by removing fuses or by cutting power supply to the SCR system. For Mercedes trucks the installation will be a little more complicated and apart from the emulator there will be extra wire harness and adapters to be installed. Can Smart emulator for Mercedes trucks will come as a full kit for the easiest installation possible. Scania adblue emulator will also require extra harness as the can line connection needs to be taken from under the cab and wire harness routed to the front of the cab. Again, our Scania euro 5 adblue emulator will come as a full kit, or you can make your own wire extension.

We believe we can offer an exceptional solution for customers, especially for trade customers, looking for top quality euro 4 and euro 5 adblue emulators. Our Can Smart Universal emulator will automatically recognise the vehicle once installed and run the correct software. You do not need to program it or do anything else, simply install the emulator to any euro 4 or euro 5 truck and the emulator will do the rest. It will even take care of any SCR or Nox related error codes so even if your vehicle already has problems with these systems or even if your vehicle is in limp mode, you can still fit Can Smart Universal emulator and all these problems will go away like magic.. (please note, in some cases you will need to drive the vehicle for a bit after installing the emulator for the error lights to go away) Our universal adblue emulator is suitable for the following euro 4 and euro 5 standard trucks:

Euro 6 standard trucks will have completely different adblue emulators and different installation. Special attention should be paid to Volvo, Renault, DAF and Scania Euro 6 trucks. Volvo and Renault trucks (normally made between 2013 and 2015) can be Euro 5 + standard, which is not really euro 5 nor euro 6 – it is a hybrid in between these. These vehicles will require a dedicated emulator, neither euro 5 or euro 6 adblue emulator will do on these. As for Scania, euro 6 trucks there are two possible adblue emulator variations. One is for so cold ‘old generation’ systems; these are normally in trucks made between 2013 – 2017, and the new generation, 2017 – 2020. The emulator will be the same however the software is slightly different; hence the correct program has to be uploaded for successful installation. Same goes for DAF trucks, there are two software variants. One will suit DAF trucks with EAS3 ECU (2013 – 2017) and the second for trucks with EAS4 ECU (2017 – 2020) These details are very important as incorrect software will result in emulator not working as it should.

Whichever truck you need the emulator for you can rest assured buying it from us will ensure your adblue emulator installation will be successful. Not only will you receive top of the range adblue emulator, but also detailed instructions, access to our dedicated online tech support and 2 year warranty with every product.

DAF LF EURO 4/5 adblue emulators are completely different from other daf emulators. This is due to the fact that DAF LF has a different engine and different SCR and Nox systems.  Whereas simple DAF EURO 5 adblue emulator is suitable for all main models such as DAF XF105, DAF CF85, DAF CF75… DAF LF 45 and DAF LF 55 models require a dedicated adblue emulator, which is suitable for CUMMINS engines.  Please note, DAF CF65 can be equipped with any of the two engines used by DAF – PACCAR or CUMMINS. Please pay attention to engine model when ordering emulator for DAF CF65 truck.

We have been supplying cummins emulators for many years now and are confident that our CAN SMART CUMMINS emulator is one of the best on the market today. Our CUMMINS range includes three products at the moment: adblue+nox emulator, adblue+nox plug & play emulator and lastly nox emulator. These emulators are suitable for DAF LF EURO 4 and EURO 5 Trucks. First, lets review our adblue+nox emulator which has 4 wires to be connected. As with all our products, daf lf emulator comes with full photographic instructions and tech support should you need it. You should estimate emulator installation time to be around 30 minutes. It offers full SCR and nox disconnection and can even be fitted to LF truck which already has problems relating to these systems. You should not expect to be able to do this withc cheap Chinese or Turkish emulators.

If there were SCR related faults prior to installing he emulator, normally these errors will go away without the need to erase them with diagnostic tool. However, if the vehicle had active Nox fault, which was there for some time, it will stay there after installing the emulator. If Nox fault stays, the vehicle must be driven under load (with emulator fully installed) It normally takes 20 – 50 miles of driving under load after installing the emulator for active Nox faults to go away. For active Nox fault to be cleared, ECU need to run test and register the correct signals sent by the emulator so that it thinks the fault was repaired. Such test are only run once exhaust system reaches required temperature, hence the vehicle needs to be driven under load for its exhaust to reach such temperature.

Active Nox faults can also be cleared instantly with dealer level diagnostic tool. If you do not have the access to such tools, the only other way is to drive the vehicle under load as explained above.


Can Smart emulator will emulator the following components:

NOx sensor
SCR module
Adblue pressure sensor
Adblue pump
Adblue pump heater

Please note, Can Smart emulator does not emulate Adblue tank level sensor. It must be in working condition for the emulator to perform 100% Your adblue level will stay the same as before installing the emulator, whatever you have in the tank – that is what the gauge will be showing.

Adblue temperature sensor must also be in working condition, as data from this sensor is sent directly to the vehicle’s ECU and therefore it is impossible to emulate via the adblue emulator.

We can also offer a much easier emulator to install – our plug and play cummins emulator. This emulator simply plugs in to nox sensor place and you are done. Installation time 5-10 minutes and you get the same benefits as with our wired emulator.

Lastly we have our cummins nox emulator. This comes as a PCB (printed circuit board) You would need to remove nox sensor from the vehicle, open it and switch pcb’s over. Then you would need to re-seal the nox box and place nox sensor back in its place. This emulator will only emulate nox system, your adblue system will stay as it , continue to use adblue liquid etc..

We are in the last stages of developing adblue emulator for DAF LF EURO 6 trucks and will post an update as soon as it is ready for retail.

Should you have any questions in regards to DAF LF or other trucks, please do not hesitate to contact us.
