Not sure if there is a thread for this yet. But I have a 2019 mustang GT when a “wrench light” just went on this morning. I took it to get scanned no trouble shoot code popped up. The vehicle isn’t in limp mode and I can still drive through the different modes. Anyone have an idea? Thanks
 
Turned the vehicle on this morning and the wrench light is no longer there. Will pay attention if it comes up again though. Thanks!

Take a quick look at your throttle body by pulling the air inlet tube off - see if there’s any traces of oil. I’ve seen the wrench light come on with no codes if you’re getting oil from the driver’s side crank vent sucked into the CAI. This could be caused by overfilling the oil - which is a possibility when you had the oil changed?
