AdBlue crystallisation | Wrong Fuel Emergency

1. Freezing Point: AdBlue has a freezing point of approximately -11°C (12°F). This means that at temperatures below -11°C, AdBlue can start to freeze and form crystals.

2. Storage and Handling: To prevent AdBlue from crystallizing, it's important to store and handle it properly. AdBlue should be stored in a cool and dry place, away from direct sunlight and extreme temperatures. If AdBlue freezes, it can expand and potentially damage its container.

3. Thawing: If AdBlue has crystallized due to cold temperatures, it can be thawed and used again once it reaches its liquid state. Simply allowing the AdBlue to thaw at room temperature should suffice. Do not use any heating methods to speed up the process, as this could damage the solution.

4. Vehicle Systems: Most modern vehicles equipped with SCR systems have built-in heating elements and temperature sensors to prevent AdBlue from freezing in the vehicle's tank and supply lines. The vehicle's system will warm up the AdBlue as needed to keep it in liquid form.

5. Preventing AdBlue Crystallization: If you anticipate cold weather, make sure to keep your vehicle in a heated environment or use parking heaters, if available. This will help prevent AdBlue from freezing and ensure that your vehicle's emissions control system continues to function properly.

6. Buying AdBlue: When purchasing AdBlue, ensure that you're buying it from reputable sources to ensure its quality and composition. If the AdBlue you buy has been exposed to extreme cold temperatures for a prolonged period, it's a good idea to inspect it for any signs of AdBlue crystallization before using it.

7. Checking Quality: If you suspect AdBlue crystallisation or frozen, you can visually inspect it for any signs of solidification or crystal formation. If you notice any abnormalities, it's best to consult the manufacturer's recommendations or seek advice from a professional.

Overall, AdBlue crystallisation in cold temperatures, proper handling, storage, and the vehicle's built-in systems are designed to mitigate these issues. If you're concerned about AdBlue crystallization, refer to your vehicle's owner's manual or contact the manufacturer for guidance on maintaining the proper functionality of your SCR system in different weather conditions.
