I've never gotten a "low DEF" warning but I did get a CEL at about 4k miles that turned out to be system related.The dealer said that a pump (or valve) in the system malfunctioned and had to be replaced.It took them a couple of days to reach this conclusion and another week to get the part in from Deutchland.At the time the service manager admitted to me that they're pretty much flying blind when working on the diesels because they've seen so few of them (mine was one of the first produced for North America).But it's 19k miles and 15 months later and the DEF system has worked fine.
