On way to delete/tune and engine light came on
Just crossed the 100k mile mark w a 3rd gen ecodiesel and im on my way to get the truck tuned.
After fueling up, the check engine light came on - i was going to have it tuned tomorrow morning.
Pulled over and going to have it looked at by closest dealership tomorrow.
No messages or codes.
Not sure what to do except get it looked at, any advice would be helpful.
