What Happens When Small Amount of AdBlue In Diesel Tank

AdBlue is a urea-based solution designed to reduce harmful emissions in diesel engines. It is stored in a separate tank and injected into the exhaust system, not the fuel tank. When AdBlue mixes with diesel fuel, it can cause several problems:

• Corrosion of fuel system components: AdBlue is corrosive to metals and rubber parts inside the fuel system.

• Fuel contamination: Even small amounts can contaminate the diesel, affecting combustion.

• Engine damage: Contaminated fuel can cause poor engine performance, misfires, or failure to start.

• Costly repairs: Damage to fuel injectors, pumps, and filters can be expensive to fix.

  
  

Because AdBlue is water-based and chemically different from diesel, it does not combust properly and can cause blockages and corrosion.

How to Identify If You Have AdBlue in Your Diesel Tank

If you suspect you have put AdBlue in your diesel tank, look for these signs:

• Engine struggles to start or won’t start at all.

• Rough idling or stalling.

• Warning lights on the dashboard related to the fuel system.

• Unusual smells or smoke from the exhaust.

• Fuel smell that is different from normal diesel.

  
  

If you notice any of these symptoms shortly after refueling, stop driving immediately to avoid further damage.

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

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

2. Do not drive the vehicle. Moving the vehicle can spread the AdBlue through the fuel system.

3. Contact a professional recovery service. Forecourt Rescue Suffolk at 01473 875186 offers expert assistance for fuel contamination issues.

4. Inform the rescue team about the AdBlue contamination. This helps them prepare the right equipment and plan the recovery.

5. Arrange for the vehicle to be towed to a workshop. The fuel tank will need to be drained and cleaned professionally.

When you call a specialist like Forecourt Rescue Suffolk, they will:

• Drain the entire fuel tank. Removing all contaminated fuel is essential.

• Flush the fuel system. This includes fuel lines, filters, and injectors to remove any residue.

• Inspect for damage. They check for corrosion or parts that need replacement.

• Refill with clean diesel. After cleaning, the tank is refilled with fresh fuel.

• Test the vehicle. They ensure the engine runs smoothly before returning the vehicle.

  
  

This process prevents long-term damage and restores your vehicle to proper working order.

Can You Fix This Yourself?

Attempting to fix AdBlue contamination without professional help is risky. Draining and flushing the fuel system requires special tools and knowledge. Mistakes can lead to more damage or safety hazards. If you are not experienced, it is best to call a professional service immediately.

Preventing AdBlue Contamination in the Future

To avoid this costly error, follow these tips:

• Know your vehicle’s fuel system. Diesel vehicles with AdBlue have separate tanks clearly marked.

• Check the pump before refueling. Make sure you use the correct nozzle for diesel.
