I have a 2017 3500 Sprinter with a Forester box mounted on it. I don't have the steering wheel info buttons, so I get limited info from the two buttons on the dash face to the left of the odometer. Recently, I started getting a message that read 4 d, or maybe d 4 flashing a few times upon turning on the ignition. Two days later, when I started it again the message has changed to 6 d, or maybe d 6, I can't remember. It flashes a few times and goes away. No warning light illuminate up top and I can't get any additional info with the 2 buttons to the left of the odometer. Checked all fluids and the obvious stuff and all seems fine. Any ideas or hints? I can't find it listed in any of the published M/B Sprinter error codes. Thanks for any help. Engine only has 3000 miles on it. Only one visit to the shop with DEF problem. Replaced some sprayers and seemed to fix that.
Thanks again.
Thanks again.
