But there is a small, often overlooked vulnerability: Crystal formation in the SCR system. This is exactly where DEF Anti Crystal Additive comes into play.\u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\u003cspan class=\"base\" data-ui-id=\"page-title-wrapper\" data-hyphenated=\"\"\u003e \u003c\/span\u003e\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv\u003eIn practice, deposits and crystal formation occur in the AdBlue® tank, in lines or injectors on many vehicles – especially when driving short distances or in winter.
