The AdBlue system fault warning light and the dreaded "Cannot start for X km" message have become one of the most frustrating and costly breakdowns for modern diesel vehicles.
If your car has entered protection mode or you're tired of the constant SCR system failures, we offer a permanent solution.
What is AdBlue and Why Does the System Fail?
AdBlue is a urea-based additive that is injected into the exhaust system.
Inside a special catalyst (SCR - Selective Catalytic Reduction), this liquid reacts with polluting gases (NOx) and converts them into nitrogen and water, which are harmless.
Although it is an effective technology for reducing emissions, its complexity makes it very prone to failure, especially due to:
• AdBlue crystallization : The liquid can crystallize at low temperatures or by evaporation, clogging the injector, pipes or pump.
• Sensor Failure: NOx sensors, which measure system efficiency, are expensive and sensitive components that can fail.
• Pump or Injector Failure: These are delicate parts that can fail, preventing AdBlue from being injected correctly.
• Poor Fuel or Additive Quality: Under certain circumstances, poor quality fuel can affect the system, as can contaminated or degraded AdBlue.
When the system detects a fault, it activates a kilometer countdown that, when it reaches zero, will prevent the vehicle from restarting as an environmental protection measure.
The Solution: Benefits of Permanent AdBlue Cancellation
-
End of Countdowns and Emergency Modes:
The risk of the car going into safety mode or preventing you from starting is completely eliminated. Drive with complete peace of mind.
-
Economic Savings and the End of Fillings:
You eliminate not only the recurring cost of refilling the AdBlue tank, but above all, the risk of facing extremely expensive repairs (NOx sensors, pumps, cooling units).
control, etc.). -
Increased Reliability:
The vehicle becomes more robust and reliable, especially if you operate in conditions where the AdBlue supply is difficult or fuel quality is uncertain.
-
System Simplification:
By overriding a complex and fault-prone system, you drastically reduce the likelihood of future electronic failures.
Legal Notice and Real Consequences: VERY IMPORTANT!
At Digi-Tec, transparency is our priority. Before requesting this service, it's essential that you understand the following implications:
Legality and Use: Deactivating emission control systems such as AdBlue/SCR is illegal in Spain and the European Union for vehicles circulating on public roads.
This service is intended for vehicles for export to countries without equivalent emissions regulations, or for use on private premises. It is the customer's sole responsibility to comply with current legislation.
Manufacturer's Warranty: Performing this modification will void the vehicle's official warranty.
