Adding the wrong fluid to your vehicle’s fuel tank can cause serious problems. One common mistake some diesel vehicle owners make is accidentally putting AdBlue into the diesel tank. Even a small amount of AdBlue in the diesel tank can lead to costly damage if not handled properly. This post explains what happens when AdBlue enters the diesel tank, how to recognize the problem, and what steps to take to fix it quickly and safely.
Small Amount of AdBlue in Diesel Tank by Mistake
AdBlue is a liquid solution made of urea and deionized water. It is used in diesel vehicles equipped with Selective Catalytic Reduction (SCR) systems to reduce harmful nitrogen oxide emissions. AdBlue is stored in a separate tank and injected into the exhaust system, not the fuel tank.
Putting Small Amount of AdBlue in Diesel Tank by Mistake:
AdBlue is corrosive to engine components: It can damage fuel injectors, fuel pumps, and other parts designed only for diesel fuel.
It does not combust like diesel: AdBlue will not burn in the engine, causing performance issues.
It can cause engine failure: Even a small amount mixed with diesel can lead to costly repairs.
Understanding this difference is key to knowing why you must act fast if you add AdBlue to your diesel tank by mistake.
Signs You May Have Put AdBlue in the Diesel Tank
If you accidentally add AdBlue to your diesel tank, your vehicle will usually show symptoms quickly. Watch for these signs:
Engine warning lights: The check engine or diesel particulate filter light may come on.
Difficulty starting the engine: The engine may crank but fail to start or run roughly.
Loss of power: The vehicle may hesitate, stall, or lose power while driving.
Unusual noises: You might hear knocking or irregular engine sounds.
Fuel smell or leaks: Sometimes you may notice a strange smell or fluid leaking near the fuel system.
If you notice any of these symptoms after refueling, stop driving immediately and check the fuel you added.
Immediate Steps to Take If You Put AdBlue in the Diesel Tank
Time is critical when dealing with AdBlue contamination in the diesel tank. Follow these steps right away:
Do not start the engine if you realize the mistake before turning the key.
Do not drive the vehicle if you notice symptoms after starting.
Call an AdBlue in diesel tank specialist immediately. For example, you can contact 07459 909935 for expert advice and assistance.
Drain the fuel tank as soon as possible to remove the contaminated fuel.
Flush the fuel system to clear any remaining AdBlue residue.
Refill with clean diesel only after the system is fully cleaned.
Trying to drive or fix the problem yourself without proper tools and knowledge can cause more damage.
Why You Need a Specialist to Handle AdBlue Contamination
Removing AdBlue from a diesel tank is not a simple task. It requires specialized equipment and experience to avoid further damage. A trained specialist will:
Safely drain and dispose of contaminated fuel.
Thoroughly clean the fuel tank and fuel lines.
Inspect and replace damaged parts like fuel filters or injectors.
Test the vehicle to ensure it runs properly after cleaning.
Calling an expert like the AdBlue in diesel tank specialist at 07459 909935 can save you money and stress by preventing costly repairs.
How Much Damage Can a Small Amount of AdBlue Cause?
Even a small amount of AdBlue in the diesel tank can cause problems. For example:
Less than 1 liter mixed with diesel can cause corrosion in fuel system components.
1 to 5 liters can lead to fuel injector failure and engine misfires.
More than 5 liters often requires a full fuel system replacement.
The severity depends on how much AdBlue was added and how long the vehicle was driven with contaminated fuel. Acting quickly reduces the risk of permanent damage.
Preventing AdBlue Mistakes in the Future
Avoiding this costly mistake is easier than fixing it. Here are some tips:
Label fuel and AdBlue caps clearly to avoid confusion.
Refuel in well-lit areas to see the tank openings clearly.
Double-check the fuel type before filling.
Keep AdBlue containers separate from diesel fuel cans.
Educate anyone else who drives or refuels your vehicle about the difference.
Taking these simple precautions can save you from a stressful and expensive situation.
What to Expect During the Repair Process
If you call a specialist, here’s what typically happens:
The vehicle is inspected to assess contamination.
The fuel tank is drained completely.
The fuel system is flushed with cleaning agents.
Fuel filters and possibly injectors are replaced.
The vehicle is tested for proper operation.
You receive advice on how to avoid future mistakes.
Repairs can take a few hours to a day depending on contamination severity. Costs vary but are much lower if caught early.
