Regen and wrench light
Today on my drive home from work, my truck started to clean exhaust filter. After a couple of minutes the wrench light came on. It continued to cleaning the exhaust. Anyone have any idea what could be causing this? Its a 08 6.4. Thanks

I had the wrench show up on my F150 at one point and it didn't affect the performance at all, it went away at the next start up. The manual does explain certain conditions where the wrench will come on. It is supposed to put the engine into "Limp Home" tune mode so it is still drivable and doesn't leave you stranded.
I would hook up and OB2 reader and get the code thrown or have a Ford tech tell you just what system is giving grief to the point of throwing the wrench code on.
It could be the Muffler Bearing, I hear there were week on that year of truck
