AdBlue in Fuel Tank by Mistake Cambridge

AdBlue is a liquid solution made of urea and deionised 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 engine.

Putting AdBlue in fuel tank by mistake Cambridge can cause severe damage because:

• AdBlue is corrosive to engine components and fuel system parts.

• It can contaminate the diesel fuel, leading to poor combustion.

• The vehicle may fail to start or run properly.

• Repair costs can be high if the engine or fuel system is damaged.

  
  

Understanding this helps explain why immediate action is necessary if AdBlue enters the fuel tank.

Signs You May Have Added AdBlue to Your Fuel Tank

Sometimes it’s obvious when a mistake happens, but other times you might only notice after the vehicle behaves strangely. Watch for these signs:

• The engine won’t start or struggles to start.

• The vehicle runs roughly or stalls soon after starting.

• You notice a strong chemical smell near the fuel filler or exhaust.

• Warning lights related to the engine or emissions system appear on the dashboard.

• Fuel system leaks or unusual noises.

  
  

If you suspect AdBlue contamination, do not drive the vehicle any further.

Immediate Steps to Take After Adding AdBlue to the Fuel Tank

If you realise you have put AdBlue into your fuel tank, follow these steps:

1. Do not start the engine. Starting the engine will circulate the AdBlue through the fuel system, increasing damage.

2. Call our professional service immediately. In Cambridge, you can contact specialists at 0330 122 6640 for advice and assistance.

3. Avoid trying to drain or fix the problem yourself unless you have the proper equipment and knowledge.

   
   

Taking quick action can reduce the risk of costly repairs.

How Professionals Handle AdBlue Contamination in the Fuel Tank

When a vehicle arrives at a garage after AdBlue contamination, mechanics usually follow these steps:

• Drain the entire fuel tank to remove all contaminated fuel and AdBlue.

• Flush the fuel system including fuel lines, filters, and injectors to clear any residue.

• Inspect fuel system components for corrosion or damage.

• Refill with clean diesel fuel and test the vehicle thoroughly.

  
  

Preventing AdBlue Mistakes in Cambridge

Prevention is better than cure. Here are some tips to avoid putting AdBlue in the fuel tank:

• Know your vehicle’s tanks. AdBlue tanks usually have blue caps, while diesel tanks have green or black caps.

• Read labels carefully before refuelling or topping up AdBlue.

• Ask for help at fuel stations if you are unsure.

• Use separate containers for AdBlue and diesel if you top up yourself.

• Keep AdBlue and diesel nozzles apart to avoid confusion.

  
  

Many drivers in Cambridge find these simple steps save them from costly errors.

What to Expect After Repairs

After your vehicle has been serviced for AdBlue contamination:

• The engine should run smoothly without warning lights.

• Fuel efficiency should return to normal.

• You may notice a slight delay in performance initially as the system resets.

• Keep an eye on the vehicle for any unusual behaviour in the following days.

  
  

If problems persist, return to your mechanic promptly.
