Fleet reliability has always depended on a multitude of factors, but many would agree that the most important aspect of a reliable fleet would be having quality servicing. Repairs covered under warranty which are done by official brand representatives are usually trusted by fleet owners.

Yet, poor management and low control standards in some countries make it hard to trust even official representatives with repair jobs: unknown use of aftermarket or fake parts and unfair practices run rampant in the truck industry in poor parts of Europe and neighbouring nations. Warranty or not, it is difficult to avoid issues such as time constraints, servicing costs and additional parts.

One of the main dangers of servicing abroad is part fraud: cheap, fake parts can be used without your knowledge to do repairs on your vehicle, sometimes even without the knowledge of the mechanic himself. They can be very hard to distinguish from the originals and usually do not set off any red alarms until already installed, usually needing additional repairs after a short amount of time. It is always a good idea to ask directly about the parts used in the repair and refuse it if they are do not want to provide you with exact details, including the brand, country of origin, part/serial numbers and an inspection of the part.

To further ensure proper service, make sure to receive a log with all of the steps taken by the mechanic to install your new part. Something like a NOx sensor change shouldn’t take over an hour to do, nor should an SCR catalyst replacement take less than a few hours to look into. You might also consider looking at the price of repair as a good indicator, as a significantly cheaper price compared to competition might mean that lower quality parts or improper procedures are being taken to do repairs on the vehicle.

But regardless if repairs are successful, there is still a massive potential time loss which can be quite a setback both for contracted jobs and the driver. Can Logic Ltd. offers the DTC Cleaner to delay issues until the opportunity to repair the vehicle at a trusted fleet service. The driver would be able to use the device at any point in time to clear faults from the dashboard and continue driving to his destination, finish the job at hand and then tend to repairs.

adblue emulator illegalAdBlue emulators have been used throughout the United Kingdom as a means to save money – fleet owners avoid costly repairs and spending lots of money on AdBlue fluid with a simple installation of different types of AdBlue emulators or cheat devices.

Yet, with road inspections becoming an often seen trend in the United Kingdom, people are starting to move away from the devices in favour of using the system as originally intended due to the legal repercussions. AdBlue emulators are strictly illegal to use within the United Kingdom, with the penalties for using AdBlue emulators ranging from warnings and mandatory servicing to a hefty fine.

As it stands, Can Logic Ltd. are against AdBlue emulator installation for anyone that operates a fleet in the United Kingdom as the SCR system prevents toxic chemicals from escaping into the surroundings which can otherwise be very harmful to our environment.

Despite this, AdBlue emulators can be used in perfectly legal professional settings which require high quality emulation of an SCR system:

  • Trucks that operate outside of Europe can use AdBlue emulators if urea is rarely found around truck stops and fuel stations. At any point if you enter a non-EU country that does not have harsh emission laws you can activate an AdBlue emulator to save urea for the journey back. If the vehicle will be out of urea and there are no ways of filling up the AdBlue tank the vehicle will go into LIMP mode until you manage to refill the tank.
  • Export vehicles are also one of the main users of AdBlue emulators due to its ease of management compared to software rewrites. At any point you will be able to restore the vehicle to its normal state, turning on the SCR system if you enter countries with specific emission laws. Alternitavely, you could remove the SCR system completely to sell for parts and permanently install an AdBlue emulator, making a small profit from the “conversion”.
  • Euro standard emission conversion is also one of the ways to use AdBlue emulators. Businesses that provide conversions from Euro 5 to Euro 6 vehicles can benefit from a high quality AdBlue emulator due to its simplicity. You simply install a device that can imitate the AdBlue system of the vehicle accurately and then install the upgraded system in its place, removing the need of another software conversion and making the changes revertible.

However, not every emulator can be used for these purposes, as most cheaper emulators (like the infamous Chinese emulators) do not fully emulate the SCR system. Cheaper low quality emulators emulate an SCR system which is not activated due to a low catalyst temperature, which prevents the vehicle from activating the SCR system and makes the vehicle spend more fuel to “heat up” the catalyst. This can lead to complications in the future, including permanent damage to the catalyst (which is the most expensive and important part of the SCR system).

We at Can Logic Ltd. offer emulators which will fully imitate the SCR system in a reliable fashion including the SCR control unit, injector, AdBlue pump, AdBlue level sensor, the AdBlue tank itself (with the heating system) and the NOx sensor all while maintaining dynamic values. Furthermore, with additional limited warranty and tech support you will not only receive a reliable AdBlue emulator, but you will also have the guarantee that it will stay fully functional throughout its use.

Fitting AdBlue emulators has been a way of reducing fleet operation costs for many years now: they remove the need to buy urea and ensure that no AdBlue faults will interrupt your journey, be it present or potential ones. Within the years fleet companies in specific European countries find it almost mandatory to fit AdBlue emulators due to the high repair costs associated with SCR systems which often exceed thousands of euros.

Despite the potential risks that AdBlue emulators bring to a company it would often be more profitable to operate a fleet with AdBlue emulators installed and accept the fines rather than fixing the SCR system. Typically manufacturers set a 2 year warranty if genuine parts are used and installed by genuine manufacturers, but considering the costs of repair smaller businesses are almost forced to use them or face significant losses.

However, recent regulation changes (the UK being the best example) have made companies remove AdBlue emulators in fear of very high fine costs, further vehicle inspection and potential license revocations. The stigma surrounding AdBlue emulators has risen to such levels that some compare it to putting magnets onto tachographs – fleet owners are now seeking better alternatives to keep their fleet on the road for longer before the rapid control checks spread towards neighboring countries.

To prevent the potential risks of AdBlue emulators, CanLogic offers the DTC Cleaner as a solution that allows you to temporarily use your vehicle in the case of SCR system faults.

The DTC Cleaner is a device that clears all faults from the dashboard of the vehicle, connecting to the control units of the vehicle and clearing their fault memory. While not a fix, it is a temporary solution that can delay repairs of the SCR system since it can be used as many times as needed before ultimately deciding for SCR system repairs.

Best of all? It acts exactly like a “Clear all” button on a diagnostics system, which means it is fully legal and there are no risks associated with it.

Main features of the DTC Cleaner:

  • Clear inactive faults from the dashboard instantly
  • Reset the LIMP mode timer
  • Easy plug-and-play functionality
  • No need for special equipment
  • Incredible value for money

AdBlue emulator packIn the end, if someone were to buy 10 or 20 units they could potentially suffer from the lack of support from the manufacturer and no other option but to accept the issues/loss of money. This is most often the case with Chinese-made emulators, which can cost very little but can actually reduce fuel efficiency and also damage the vehicle’s SCR system in the process due to poor software copied from another version of the emulator.

CanLogic Ltd. has developed an emulator for Euro 4 and Euro 5 vehicles that is not only reliable but is also easy of use, packed with features and uses high quality automotive-standard components. Not only are they assembled in the EU but they are also thoroughly inspected and tested before being sent, having close to no risk of faulty units as a result.

AdBlue emulator packages are bundled with a touch-screen programmer with which you can program the units for different makes. This makes it an ideal solution for small businesses or private mechanics, no matter for what purpose: client instalation, SCR system removal for vehicle export, reselling etc. By buying packs you also benefit from significantly reduced prices.

CanLogic offers AdBlue emulator packages that can be programmed with a variety of Euro 5 vehicles:

  • Euro 4 and Euro 5
  • SCANIA (R, P, G)*

  • Emission fault clearing technology

An SCR system is used to reduce the amount of exhaust emissions from vehicles. It breaks down the various chemicals within the exhaust fumes into mostly water and nitrogen, which are much better suited for the environment. To operate properly, the SCR system needs to be supplied with AdBlue, which is a simple, non-toxic solution made with about 32.5% synthetic urea and 67.5% deionised water.

How does it work?

The process is simple to understand and does not require extensive knowledge to have a basic understanding.

The main components of the SCR system are the catalytic converter and the injection pump/doser.

  • The vehicle outputs noxious emissions, including NOx.
  • The emissions are filtered at the DPF (Diesel Particulate Filter) to remove a large amount of soot.
  • When reached a certain point, the gases are then sprayed by the pump/doser with AdBlue, which separates NOx into ammonia (NH3) and carbon oxide (CO2).
  • The resulting mix then goes into the catalytic converter, which helps to create a chemical reaction, where the emissions are separated into nitrogen (N2) and water (H2O).

Components like the SCR control unit, NOx sensor, AdBlue pressure sensor and temperature sensor are there to control and monitor the system, ensuring that every component is operational.

  • The SCR system does not work until the fluid temperature is at least at 220C, power consumption is 20% and the RPM is at at least 1000.
  • NOx sensors constantly monitor the amount of noxious emissions from the vehicle to identify if the SCR system is doing its job.
  • The SCR control unit is the brain behind the whole system. It monitors all of the sensors to calculate the AdBlue injections amount and type. It also controls the heating unit that brings the gases to an acceptable temperature for the chemical process to take place.
  • The AdBlue pressure sensor makes sure to record the pressure of the AdBlue fluid, which will affect the injection.
  • The temperature sensor monitors the temperature of the AdBlue and emission gasses, bringing it up if it is not warm enough. If the temperature is off, the fluid will be heated beforehand.

There are differences in the SCR systems between the last 3 Euro-standards:

  • Euro 4: no NOx sensors
  • Euro 5: typically 1 NOx sensor after catalyst (DAF trucks being an exception, with two)
  • Euro 6: DPF, 2 NOx sensors (before and after catalyst

How is the SCR system emulated?

Our CanSmart emulators send specific signals that indicate that the SCR system is fully functioning. This includes the following components:

  • SCR control unit
  • Injector
  • AdBlue pump/doser
  • AdBlue level sensor
  • AdBlue tank with heating system
  • NOx sensor

The values are well balanced and imitate the SCR system very well, making it an ideal choice when the SCR system is not working or is not needed.

Cheaper emulators have workarounds or sloppy implementation which means that the SCR system will be emulated improperly. For example, some emulators rather than emulating a working SCR system will only emulate the temperature sensors around it.

This makes it easier to emulate the AdBlue system since you do not need to have dynamic values on the various components, but it can be harmful to your vehicle if the temperature values are not adjusted properly. The reason for that is the heating system tries to heat the AdBlue tank whenever the temperature of the exhaust is too low, which might lead to significant damage to the tank and also uses extra fuel to heat it up. This method of emulation is especially prevalent in Euro 5 AdBlue emulators (cheap copies and chineese units).

If you would like to purchase a safe to use, fully working AdBlue emulator then you can always go to our AdBlue emulator page or contact us directly.

Cummins AdBlue emulatorVehicles with Cummins engines are notorious for having SCR systems which are expensive to fix. Cummins parts are not only rare in the EU, but they are also as unreliable as any other SCR systems, making the repair bill even larger than usual.

Thankfully, CanLogic offers a solution for the issue.

The CanSmart Cummins AdBlue emulator works with most European Cummins-based trucks and can fully imitate both the SCR and NOx systems up to the last bit of detail. Not only is the emulator much cheaper than a full on SCR system repair but it also is faster and easier to do. In the end you also do not need to worry about any other component being faulty as well, improving the overall reliability by a huge amount.

Recently, we had a person contact us, explaining that he bought a Euro 4 DAF LF45 which had cost him a lot of time and money. He spent over £6000 SCR repairs alone and wasted a lot of time going from replacing one part to another. He needed something to solve his issues and he had never found a solution for DAF LF trucks anywhere else.

The DAF LF emulator was not only the perfect solution for him, but also he was pleased to hear that it is incredibly easy to install: only 4 wires to connect (CAN High, CAN Low, positive and ground) and a small plug to put onto the temperature sensor. Additionally, you also get 2 years of warranty with the product, which makes it all the more worthwhile.

LIMPWhenever you drive a truck with an SCR system, you risk to spend upwards to £4000 on SCR system repair as well as letting your clients or partners down.

And it is not a secret how the SCR system works and why it fails: multiple sensors pick up the emission levels at different stages of breaking down the noxious gases, making sure that each step meets the set requirements of the EU emission standards.

If any of these sensors fail or pick up even a small irregularity within the process, the SCR system will shut down and their vehicle will go into LIMP mode after some amount of time. What’s more is that when you realise the vehicle does not rely on the SCR system to function properly, it is then that the frustration kicks in.

The DTC Cleaner

The DTC Cleaner solves this exact issue in a very easy manner. It can clear any inactive fault from the dashboard and reset any active errors, including the SCR LIMP timer. It works just like a diagnostics system would clear faults, but without all of the hassle: no computer interfaces, no software, no confusion. Simply turn on the ignition, plug in the device into the diagnostics port, wait 20 seconds and you are ready to drive once again.

One of our clients has recently shared an issue that he had on the road that was easily solved. He travelled to Greece from the UK (about 1800 mi) on his Volvo FH, expecting to be there early, with plenty of time left for sleep. Once he entered Germany, his truck had issues with the SCR ECU, leaving him with a difficult decision: either repairing his vehicle in Germany or continue to drive towards Greece (another 1200 mi) and back with a 40% power limit.

Which ever way it is, both choices were going to leave him with time wasted on either repair or sluggish delivery. Repair was his ultimate choice – he was quoted 3450 EUR for full repairs (almost £3000). His financial losses due to the trip were tremendous, not to mention his detour that lasted 2 working days.

Since the episode, we have discussed the possibilities of avoiding such situations. The DTC Cleaner seems to be the perfect solution for delaying the situation until back home, visiting your own favourite repair shop.

And if there is no possibility to do that right away, you can delay the situation a multitude of times, right until the point where you will be able to afford the repair bill and loss of a vehicle for a few days.

Cleaner logoGovernment emission standards usually require trucks to be equipped with an SCR system. This is especially true in the EU, where these regulations present very strict guidelines to emission levels. Sadly, these do not make the life for an average fleet owner easy, as the SCR system has received a hefty amount of criticism over the years: having to spend up to £2000 on a vehicle which is in great shape, albeit has a faulty emissions system, has a lot of hauliers at a loss for words for the unreliability and cost of the system.

Fortunately there have been solutions on the market that have brought reliable results. AdBlue emulators are the most sought after solution, but it is simply impossible to use them within the EU without receiving hefty fines for avoiding emission regulations. Software AdBlue removal is also possible, but is also considered illegal within the EU.

CanLogic has developed a solution that can help, guaranteed – the DTC Errors Cleaner. It can help in situations where your SCR system has developed a fault on the road and there is no possible way to go to a service or if you would like to finish the job beforehand. It simply resets Limp mode timer, giving the driver extra time to finish his duties first or drive to servicing without power restrictions affecting the vehicle.

This is incredibly useful with most trucks, since they give an acceptable amount of time until the power restriction takes effect (for example, Volvo gives you 70 hours before it caps your vehicle), but the most important thing is that you can reset the timer as many times you would like, meaning that you can keep doing it until you have the time and funds for a professional to take a look at the issue.

The best part? Any further inspection of the vehicle will not show that the Limp mode timer has been cleared – you can pretend that the fault appeared only recently.

The list of benefits goes on:

  • No need for emergency servicing

  • Can drive to your trusted service later

  • Can continue using it indefinitely

  • No need for AdBlue refills

The device is compatible with most Euro 5 and 6 trucks and comes with 2 years of warranty and a 30 day refund guarantee, so you never have to worry about faulty parts.

All in all, we feel that this device is a must have for those that consider the SCR system a hassle or for anyone that would like to ensure themselves from further damage to their vehicles.

SCRWhy do many truckers and companies with fleets go in favor of using an AdBlue emulator (sometimes illegally even)? This answer can be answered with just two words – costs and time.

1. SCR system replacement expenditure

It is widely known that SCR systems for trucks are not cheap.

And when we mean not cheap, we mean incredibly expensive. You would need to spend up to a few thousand pounds on an SCR system replacement if you do not have warranty coverage. This is exactly why many use AdBlue emulators as often as possible, when possible.

How expensive is an SCR system repair?

The average expenses for a NOx sensor replacement can cost up to €750. A single injector can run for up to €1000. A pump change can run you up to €2500. A control unit is even more expensive – €1500 on average.

Overall, the cost for a full replacement is sky-high – around €6000 or more. It is also assumed that you would not have any issues with the AdBlue tank, filter, pressure/temperature sensors etc. Furthermore, by replacing one component there is also no guarantee that another will serve you well for long enough to cover the costs. Lastly, you would need to include the cost of servicing and the loss of profits due to the vehicle being non-operational.

2. Saving time on transits

There are some transits that you simply cannot afford to fail. AdBlue emulators can serve as great emergency tools in a dire situation. Connecting an AdBlue emulator to drive to a nearby service or to finish a job before calling emergency servicing would be ideal if thousands of euros and your reputation depend on it.

An AdBlue emulator will imitate the SCR system regardless if it is in need of repair or not. All there is to do is to disable the SCR and NOx systems and connect our emulator to the vehicle. With that in mind, you can use the emulator in various ways to extend the life of your SCR system and save both money and time in the end.

AdBlue emulator logoThe SCR system proves to be quite a hassle for Euro-standard trucks outside of Europe – the costs of AdBlue and the significant repair costs of the SCR system make the use of AdBlue emulators a no-brainer. However, what other options are there?

Here are some popular AdBlue removal methods:

Software-side removal methods

Rewriting software and editing parameters is not an innovation by any means in the commercial industry. Ever since the SCR system first showed its way in trucks, many services first used these methods to disable it entirely:

  • Downgrading to Euro 3 software – one of the most dangerous methods of all. While this works well with SCR systems, the consequences of the rewrite can be grave due to the differences in the fuel system between Euro 3 and Euro 5/6 standards. The differences in the piston setups and injections nozzles have a side-effect of leaving behind some unused fuel, which can lead to fuel economy going down the drain. Furthermore, a poor mix of fuel and air due to incorrect configurations of the injection nozzles can also lead to further harm including piston meltdown, damaging them permanently and having to replace them.
  • Changing SCR parameters in the ECU configurations – Mecredes-Benz and Scania trucks can have their SCR systems turned off with a few changes to the ECU file. This can be done with dedicated software and is a great way of turning off your SCR, but only when a professional is handling the process. It is very easy to end up with a dead ECU if the parameters are tampered with incorrectly, so it’s only advised to leave this method to professionals.

Dedicated hardware – AdBlue emulators

Dedicated hardware is the safest, most reliable option when it comes to AdBlue removal. At any time, you can restore your vehicle’s default state by just removing the emulator and enabling the SCR system once again.

There is an incredible amount of AdBlue emulators, some cheaper, some much more expensive. What are the differences?

The first option are Chinese emulators – based off of European counterparts, they are the cheapest, simplest, least reliable solution. While Chinese emulators are extremely cheap when bought in bulk (around £10-20 per unit), they suffer from absence of NOx emulation (the DPF filter will clog up quickly, would have to be regenerated once per month) and poor quality hardware (faulty units, no seals preventing dust/moisture from getting inside etc). We recommend avoiding these units if you plan to use them for a longer period of time.

European emulators are the ideal choice. They use higher quality parts that make their electronics much more reliable and you can find very decent emulators that can emulate NOx as well, but there are two problems that one needs to be aware of when purchasing these emulators – components and sealing. Some European manufacturers opt to simply purchase Chinese emulators, making them no different from the Chinese ones, meaning that low quality parts make them very unreliable and you overpay by a huge margin. Others do not make sure that the unit water-proof and dust-proof, meaning that eventually it is definitely going to break.

We, at CanLogic can provide you with a quality unit that works flawlessly, emulates NOx and is safely sealed from any potential dangers – contact us for further information.
