After I get rear-ended a month ago, my 340i limped away from the scene to pull into a parking lot so we could clear the scene from rush-hour traffic.
Having observed no discernible damage that could cause such a reaction in my car, it was shocking to my wife and me and we thought it might need a flat-bed tow back home. However, everything was fine after turning the car off and on and we went home as normal.
It was only later that I realized the car went into limp-mode! WHEW!
