2018 4x4 Sprinter, 2500 with about 6000 miles. My wife was driving the van today and noticed the yellow engine light on, in a steady manner. She felt like at some point she floored the van and it wouldn’t go over 20mph (this occurred after the light was on – the light did not go on at this time). However, she then thought maybe her foot just wasn’t on the accelerator pedal all the way because she moved her foot to better press the accelerator and couldn’t reproduce it. So as of now, the light is on but the van is/was driving (an accelerating) seemingly without any issue.
According the manual it could be one of three things.
1- A fuel issue (though tank was filled recently and should have ¾ of a tank – Chevron station in a busy local so hopefully good gas). Am I interpreting the instructions correct in the manual where it says to turn the van on and off for 3-4 times to see if it resets (presumably after re-fueling – which I shouldn’t need to do)? It suggests the van is running in “emergency mode”. How would I know, just because the light is on?
2- An injection malfunction. As noted the van is seems to currently be running fine. This is less likely (I think, but what do I know?). Also apparently running in emergency mode.
3- It’s an emissions issue. This seems most likely because it seems to be the bane of this van. I did have the “add DEF fluid” message a week ago. No light per say, just the message. I added DEF and after a start or two the message was and has been gone.
Currently there are no “messages”. I am going to call the dealer, but anyone have any thoughts or suggestions? The light is not flashing, and the van seems to run fine. I think it’s safe to drive, but I’d hate to cause damage. Input here?
