2018 Porsche 718 Cayman 2dr Hatch

turbocharged 300hp 2.0L H4 6-speed manual RWD

44020 mi coolant system pipe 
50840 mi replaced pressure converter and installed new air filter to pressure converter 
23560 mi Cooling System fault indicated with caution to have Serviced. The Porsche Dealer re-seated vacuum line that is connected to a series of Check valves. Porsche uses vacuum actuated check valves for a variety of functions eg. activating Porsche Sport Exhaust. The Cooling System provides vacuum source. The fault was intermittent. Re-seating the vacuum line (which is plastic) appears to have remedied. This is not an unheard of issue with recent vintage 911, Cayman and Boxsters. A friend had same fault with his 911 GTS (re-seated line as well).
