I'm posting this for @Yopauly and it was not hot, maybe high 70's at the track.
"During a track day last Saturday at Sonoma I got an overheat message at end of a session. Gauge pegged to full hot, red overheat light came on and engine went into limp mode. I came in, opened hood and did not get any indication it was overheating (no coolant pumping on ground, no smell, no hiss etc). I started it up after 5 minutes and gauge snapped from full hot to normal and red light went out but check engine light stayed on. I drove it back home 100 miles in stop and go traffic (95 degrees outside most of the way) with no sign of overheating. When I pulled the code at home, it was P1299 which is cyl head overheat. Any ideas ?"
