How to know you have AdBlue Problems?
If you drive a diesel vehicle, you may be rather familiar with AdBlue. It is a liquid used inside diesel vehicles to help reduce the harmful emissions from the engine. AdBlue works as part of the Selective Catalytic Reduction (SCR) system. This system converts nitrogen oxides into harmless nitrogen and water vapor, which can reduce air pollution. However, when operating a diesel vehicle with AdBlue, there can be incredibly common problems that occur. There are clear signs that you are experiencing AdBlue problems, and something is wrong. One sign would be a warning light on your dashboard. These messages could include “AdBlue level low, “Emissions system fault”, or “NOx sensor error”. Another sign is that the engine may not be running as smoothly as normal and could use more fuel than normal. You may also experience a loss of power (aka limp mode).
On some vehicles, there is a countdown that appears on the dash. This tells you how many miles you have left until the engine won’t start at all. It is a safety feature that acts as a warning to give you time to fill it. Any of these signs may appear if AdBlue levels are low, injectors are blocked, or a faulty sensor. Luckily, thanks to improved technology, there is a process called AdBlue Software programming. This is a long-term fix and can stop these problems and warnings from happening to your vehicle. This helps a lot of people who deal with prominent AdBlue issues.

What is AdBlue software programming?
AdBlue software programming is a process where a specialist engineer flashes new custom-made software into the ECU (engine control unit). This software is very carefully created. Essentially, it stops the vehicle from going into limp mode for any AdBlue faults and NOx sensor problems. It also prevents any countdowns to limp mode and non-engine starting situations. This is good, as no one wants their vehicle to go into limp mode. As well as this, at ECUFlash, we can also do an ECU Remap at the same time as this process. This increases fuel economy by up to 10% and also gives you an increase in engine power. This option is best suitable for road use vehicles.
What are the benefits of AdBlue Software Programming?
- Fully reversible – One thing that encourages people to go forward and try this service is that if it isn’t for them, they can have it reversed. This is possible as when the specialist performs the AdBlue Software programming, they will keep a version of the old software stored away. If you do want to change back, it can be easily restored to the original software, and your vehicle will be the same as it was before.
- No black boxes or fuses removed – People in the motorsport industry may be familiar that the use of black boxes and removing fuses is illegal in the UK and therefore can’t be performed by a reputable specialist. However, with AdBlue Software Programming, nothing is removed. This makes it a fully legal choice and won’t put you at risk of any legal issues or fines in the future.
- No limp mode or non-engine starts – This is probably the main benefit that people look at with this service. For people who may have to commute or fleet operators who need to drive long distances, they can’t risk limp mode or their engine not starting. Therefore, this is great as these issues are avoided, and it won’t happen to your vehicle. So, it is a massive relief to customers who will be assured that their engines will continue to run.
In summary
It can be concluded that if you are experiencing any of the above issues we have talked about, then AdBlue Software Programming may be the fix for you. Additionally, it can stop warning lights and non-engine starts, which, for some people, are massive worries. It is important to note that choosing a reputable specialist is important, as they will always ensure the safety and health of the car and ensure everything is carried out professionally and safely. Technology in vehicles has come a long massively in the last few years and offers huge benefits for your vehicle.
