Typical problems of the AdBlue® fluid
However, not all can be perfect. AdBlue® is a mixture of water and 33% of urea, so it shows us four problems:
- the fluid is very corrosive
- it freezes at -11ºC
- can form crystals when the temperature of operation is below 260ºC
- it also expires after 1 year of manufacture.
One of the major concerns of this system is that AdBlue® may crystalize at low temperatures. This will lead to a blockage in the SCR, injector or pump. This situation is likely to happen in all vehicles that mainly run in town at low speeds causing a high cost for their owners.
