Update: I've been vented and wrapped for a year with no overheating or limp mode in about 20 - 25 track days (PCA white level/ MoE advanced). Had full limp mode (no boost) at the end of a 30 minute session at Watkins Glen this weekend (very hot, very humid, and I may have been overdriving the car a bit). Stock 2018 CS PDK drive train, no tune or exhaust. A couple of other times boost limited to 6 - 7 psi. Chris Brown (cbracerx here) had told me that he had one other client with similar experience - one isolated limp mode experience with otherwise protracted success with wrapped/venting.
So no big deal and no changes to my plan to track the car long-term, just wanted to update the thread.

For this weather, removing the undertray might be needed until a V2 fix with a very substantially modified undertray is developed. I do have some ideas which involve opening up much of the center of the undertray and directing air to the turbo and wastegate like the current mods do.

based solely on my experience this may not be a solution. i removed the tray completely and still had the issue. i think it may need the air being directed up but i'm no rocket surgeon.

For anyone getting the limp mode, are you getting any dash messages? I had the "transmission temp too high" message come on after about 6 laps at Sebring in the spring, but after half a lap at reduced power it went away as did limp mode.

Good to know; thanks. But there's no option on the dash screen to see manual transmission temp, right? Don't remember if my PDK 981 GTS had it, but I don't think it did either. But at least if either transmission gets too hot, we'd get a warning, which is good.

i got 3 messages every time it happened: PSM turned off, lane change assist turned off and adaptive (turning) headlights turned off. two i couldn't care less about but the first time it happened i drifted around turn 3 at daytona without trying. solution was always the same - windows up, car turned off and locked, wait 30 mins.

No dash readout unfortunately. I read the manual transmission temp through the OBD-II port using the Launch X431.
