I had the same problem when I was tracking my 718 GT4 at Sonoma Raceway. Basically, I was running low on oil and the PSIs were deep in the red. The engine light goes on and there's a msg about engine fault, see technician and then limp mode kicks in. I think this is preventative since it recognizes the lack of oil coupled with extreme driving will shortly destroy the engine. After I topped up all the lights went away. I brought it to porsche service and they tried to recreate the light, but couldn't.
