What to do if you accidentally pour AdBlue into a diesel tank?
Accidentally pouring AdBlue into a diesel fuel tank is a common mistake but can cause severe engine damage if not handled properly. The key steps to mitigate the issue include immediately stopping the engine, towing the vehicle to a service center, and thoroughly flushing the fuel system.
Accidentally pouring AdBlue solution into the diesel fuel tank is a mistake that can happen, especially since both liquids are commonly used in diesel-powered vehicles. However, if this error is detected promptly and handled correctly, you can avoid severe damage to the engine system. Below is a detailed guide on how to address this situation.
1. Immediately stop the engine
If you realize that you have accidentally poured AdBlue into the diesel fuel tank, the first and most important thing to do is not to start or continue operating the vehicle. Starting the engine with AdBlue in the fuel tank will cause the solution to be drawn into the fuel system, leading to corrosion and severe damage to engine components such as the fuel pump, injectors, and fuel filters.
2. Contact a towing service and take the vehicle to a service center.
Dealing with an accidental spill of AdBlue into a diesel tank requires a high level of expertise, so you should contact a towing service immediately and take your vehicle to a reputable service centre or garage. On-site treatment is not recommended, as the AdBlue solution may have entered the fuel system, requiring specialist equipment to drain and clean it completely.
3. Clean the fuel system

At the service centre, the technician will perform the following steps to completely clean the fuel system:
- Drain the entire solution: The technician will drain all the AdBlue that was mistakenly poured into the fuel tank. This is an important step to ensure that no AdBlue remains in the system.
- Fuel system flush: The fuel system will be thoroughly cleaned to remove any impurities or deposits that may have accumulated. This requires special equipment and solutions to ensure that the system is no longer contaminated with AdBlue.
- Check and replace parts: If AdBlue has penetrated deep into the system, certain parts such as the fuel filter, fuel pump or injectors may need to be thoroughly inspected or replaced.
4. Check the system again and restart the vehicle
After the fuel system is cleaned, the technician will check the system again to ensure that there are no more contaminants that could affect the vehicle's performance. Once everything is in order, the vehicle will be restarted to check its operating condition.
5. Notes to avoid this error from recurring
Always check the label on the tank cap before adding any solution to the vehicle. For AdBlue, its tank is usually blue or has a blue cap to distinguish it from the Diesel tank.
Understand the process and location of the tanks on the vehicle, especially if you maintain or refill the vehicle yourself.

Mistakingly adding AdBlue to the Diesel tank can cause many serious consequences if not detected and handled properly. It is important that you stay calm, do not start the vehicle and take the vehicle to the service center for timely handling.
