If you want to drive around Europe without having to worry about fines, taxes, or being unable to enter certain zones, your vehicle will need to pass the Euro 6 emission standards. For diesel vehicles, this means using a Selective Catalytic Reduction (SCR) system, which runs on Adblue.
These systems, however, are often very faulty and expensive to repair. Can they be legally circumvented with an Adblue Emulator?
Diesel Exhaust Fluid (Adblue) – what is it?
Adblue, or Diesel Exhaust Fluid (DEF), is a vital element of the SCR system. This fluid is made from a mixture of water and urea, and helps reduce harmful nitrogen oxide (NOx) emission levels to almost zero.
You can have a technician top up your Adblue during a routine inspection, or you can add it yourself in some vehicles. When getting your Adblue, make sure it meets the ISO 22241 regulation – otherwise you might be buying bootleg Adblue and risking causing an SCR system failure.
Don’t believe in miracle products like Mercedes Adblue, supposed to make certain vehicles perform better. They won’t work and might be dangerous.
What happens when an SCR system fails?
SCR system failing is a very real possibility in diesel vehicles that pass Euro 6 regulations. When the SCR system fails, the Engine Control Unit (ECU) will tell the engine to operate in a power-saving mode, which means your vehicle’s performance will be very reduced. Unfortunately, you won’t be able to do much about it and will have to ride to the closest repair shop to fix the issue, which can be very pricey.
To avoid costly SCR system repairs, many drivers use an Adblue Emulator – but is it legal?
Is using an Adblue Emulator legal?
Devices like a Mercedes NOx Sensor and other Adblue emulators are used to convince the ECU that the SCR system is still fully operational and running, even though it might actually not.
In the European Union, using an Adblue emulator is illegal, unless outside temperatures reach ultra-low levels (since Adblue can freeze in such conditions) or when driving to a repair station to fix a malfunctioning SCR system. For a low price, truckers can save on average 6000 euros each year by using an Adblue emulator in countries where it’s legal. It can also be installed in vehicles used for off-road driving.
