SCR deposits are a known problem with DEF solidifying and building up in the exhaust stream. How much of a problem is not clear, and not something I have heard much about. I think maybe more so for long haul OTR rigs. BlueDEF Platinum claims to reduce those deposits.

From their web site:

"BlueDEF Platinum is a mixture of high-purity synthetic urea, deionized water, and a proprietary formulation featuring the companies new Advanced System Shield Technology, which significantly reduces harmful deposits that commonly build up in modern diesel exhaust systems with SCR. With regular use, Old World said, these harmful deposits are significantly reduced, providing optimum fuel economy, saving money on costly repairs, and sustaining the life of the system."
