I tried the search option. Anybody have this message? "Improper DEF Detected see dealer" 374 miles on truck. 1 jug of non-expired, stored inside, 3 bears def. (dealer barely put any in it when I bought it)
 
If it happened after adding that new jug I’d suspect that. Could be a bad batch or tampered with. Drain and refill usually solves that message.
