Service Def System See Dealer message

[PD Luke]

I had the same stored message and took it in this week for service. The message cleared on my 50 minute drive to the dealer. There were no codes or messages or anything out of line when the dealer checked it in. Fortunately it was not a wasted trip as I also scheduled to have the particulate sensor recall taken care of.

Mmmmm seems like the DEF system is completely unreliable.
I picked up my new “build 2023” 2500 in Australia yesterday. With 200km on the clock. And at 630am this morning with 248km it spits the DEF see dealer warning..
Really?! I haven’t even had the truck for 24hrs.
Still waiting to hear back from the dealer.

If its been sitting with the same DEF in it since 2023 that would be the issue
