What Happens When AdBlue Enters a Diesel Tank


AdBlue is a urea-based solution designed to reduce emissions in diesel engines by breaking down nitrogen oxides in the exhaust system. It is stored in a separate tank and injected into the exhaust stream, not the fuel tank. When AdBlue is mistakenly poured into the diesel tank, it contaminates the fuel and can cause serious engine problems.


Effects on Your Vehicle


  • Fuel system damage: AdBlue is corrosive to fuel system components such as fuel pumps, injectors, and filters.

  • Engine performance issues: Contaminated fuel can cause misfires, stalling, or failure to start.

  • Potential long-term damage: If not addressed quickly, AdBlue can cause permanent damage to the engine and fuel system.


The severity depends on how much AdBlue was added and whether the engine was started after the mistake.


Immediate Steps to Take If You Put AdBlue in Your Diesel Tank


If you realize you have put AdBlue in your diesel tank, act fast to limit damage.


  1. Do not start the engine. Starting the engine will circulate the contaminated fuel and increase damage.

  2. Call for professional help immediately. In Essex, you can contact specialists at 0330 122 6640 for advice and assistance.

  3. Avoid trying to drain the tank yourself. Fuel systems are complex and require professional tools and knowledge.

  4. Inform your roadside assistance or recovery service. They can arrange safe towing to a workshop if needed.


How Professionals Fix AdBlue Misfuelling


Specialist mechanics use specific methods to clean and repair your vehicle after AdBlue contamination.


  • Fuel tank draining and cleaning: The tank is emptied and thoroughly cleaned to remove all traces of AdBlue.

  • Fuel system flushing: Fuel lines, filters, and injectors are flushed to clear contamination.

  • Component inspection and replacement: Damaged parts like fuel pumps or injectors may need replacement.

  • System diagnostics: The vehicle’s computer is checked for error codes and reset if necessary.

  • Use separate nozzles: Always use the correct nozzle for diesel and AdBlue. Many fuel stations have distinct colours and shapes.

  • Double-check before filling: Take a moment to confirm you are filling the right tank.

  • Ask for help if unsure: Fuel attendants or garage staff can assist if you are uncertain.
