Hello, folks

So, I Purchased Brand new 2017 Boxster S model this May.

Took it to the track at 2500 mile, 3-4 laps on track and noticed that it only make 5 psi of boost at the max.
Oil temp reading was 235-240 F, Outside temp was 85F.
Wasn't able to finish the entire trackday due to the limp-mode issue.. getting pissed off....

The next day, made an appointment for service. Took the car in for check up few days later.
Mechanic said that turbo was overheating and went into limp mode to protect the turbo and engine.

Over the past weekend, weather was nice around 65 degrees. So I took my 718s out for some country backroad experience.

About 5-10 mins into spirited driving and all the sudden oil temp skyrocketted to 245F and it went into Limp mode again.

Aren't these cars made for track use? My old M3 never had this issue before...

Does anyone experience this overheating issue with their new 718s?

Could this be a bad sensor? You mentioned the oil temp suddenly skyrocketed to 245F. It everything was normal, and then the temp suddenly increased that could be a sensor issue. If something else was broken (like a crack somewhere, etc), then I would think you'd see temps slowly and steadily going up, as opposed to suddenly shooting up. There was no fluid underneath the car?

Whatever it ends up being this is not normal. You should have it fixed under warranty.

i have tracked my 718 cayman s 15 days this season and never experienced what you are. actually i did not have a single problem other than playing with the tire pressures to get it right (every weekend was different weather-wise). i'll be at daytona in 2 weeks and i don't anticipate any problems there either, even with running 3/4 of the oval.

I am at about 3800 miles on my 2018 CS, and no issues with oil overheating or oil consumption. Have not tracked it but have pushed pretty hard after the 2k break-in. Haven't uncovered any issues with my Cayman at all.

I've tracked my Cayman 718 S 14 times this year, several times in 90+ degree weather. Sessions have gone as long as 30 minutes. I have not had any problems at all with oil temp, coolant temp, or reduction of power, etc. Definitely a warranty issue. Would be interesting to know what they found out to correct this for future reference. Good luck!

What were the ambient temps for the track days?
How long were the sessions?
What kind of oil temps did you max out at?

Thanks
