Avoid starting the engine, as this could potentially cause damage. AdBlue is not a fuel and can lead to engine problems if used as one.​

Driving the vehicle with AdBlue in the diesel tank can lead to engine damage.​

We can assess the situation, drain the incorrect fluid, and flush the system if necessary.

We need to drain the contaminated diesel and AdBlue mixture from the tank. Additionally, we may need to flush the fuel system to remove any remaining AdBlue.

Depending on the extent of contamination, it might be necessary to replace the fuel filters to ensure that any residual AdBlue is removed from the system.​

The technician should inspect the fuel system components to identify any potential damage caused by the AdBlue. This may include checking the fuel injectors, fuel lines, and other relevant parts.
