Hello! I did a search on the forums but couldn't find anyone with a 2017 6.7 that had the wrench light come on. In the owners manual it indicates it has something to do with the 4 wheel drive or drivetrain? Has anyone else been in this same situation? Should I go somewhere and see what the codes are? Is it OK to drive? Believe it or not I called FORD and they said it needed service, such as an oil change and that it would be OK to drive. I'm not sure he knew what he was talking about. Thank you in advance for your time and help.
