Modern diesel vehicles often have a Selective Catalytic Reduction (SCR) system installed to reduce harmful emission levels of Nitrogen Oxides (NOx). To satisfy the Euro 6 emission regulation, diesel cars need this system in addition to a Diesel Particulate Filter (DPF). Adblue is a crucial component of the SCR system – but what exactly is it, and can it be removed using an Adblue emulator?
What is Adblue?
Adblue, or Diesel Exhaust Fluid, is a mix of deionized water and urea, pumped directly into the exhaust system of a diesel vehicle to reduce NOx emissions. Since 2016 and the introduction of the Euro 6 emission standards, all diesel vehicles must have an SCR system and use Adblue to enter Ultra Low Emission Zones (ULEZs) without having to pay a fine.
As an Adblue emulator box is used up when the car is running, it will need to be topped up during each technical review. In case Adblue runs out before your next inspection, you can also add it yourself – you should have an additional gauge on your dashboard that shows Adblue levels.
Adblue is the same for all vehicles. Mercedes Adblue will be exactly the same as BMW Adblue.
What is an Adblue Emulator?
In theory, the SCR system is a wonderful invention – it reduces harmful nitrogen oxides to near-zero levels, helping eliminate greenhouse gasses emissions. Unfortunately, there are several downsides of the SCR system and Adblue, the most important of which are failures.
Whenever the SCR system fails, the central Engine Control Unit (ECU) turns the engine into a low-power mode, reducing its performance severely. If this happens, you’ll need to find a repair shop to fix the issue – which can be extremely costly. To avoid this, drivers can use an Adblue Emulator – a device that bypasses a faulty SCR system and tells the engine to continue running as usual.
How hard is it to install an Adblue Emulator?
Using a device like a Mercedes NOx sensor adblue emulator, drivers can circumvent a faulty SCR system and save money by not using Adblue wherever it isn’t necessary. Installing one might not be legal in all European countries, so check carefully the regulation before you proceed.
The installation itself is very easy, and the devices themselves are rather cheap. Most such products come with an installation guide, which makes the process incredibly easy. Some can be simply plugged to ST55A on the vehicle frame, next to the engine. After connecting the right cables to the right pins, you should be ready to go!
