Very common if you have 2014-17 mix Your DEF with 2.5 Gallons and 1 Gallon Distilled water Problem solved.

DEF is 33% Urea and 67% Deionized water.

Have been running 10-15% Urea in all My DEF Vehicles for 12 Years.

Hello, get a cheap steamer and it will look like new again. I clean mine when I change my fuel filter, since you are already under there, lol.
