PDK clutches and coolant pipes on the 718 Boxster/Cayman (982)Gearbox

Engine / equipment: Porsche 718 Boxster and Cayman (982)
Period mentioned: 2016 onwards
Symptoms: With PDK, shudder when pulling away, harsh low-speed engagement and clutch-slip codes; coolant leaks from aged pipes and hoses.
Possible cause described: The PDK clutch packs wear faster on hard-driven cars (launch control, track use). Salt and freeze-thaw cycles age the coolant pipes and hoses. The specialist garage considers the four-cylinder engine robust.
Check for the garage: Change the PDK oil and filter every 60,000–90,000 km; read the gearbox codes; pressure-test the cooling circuit on cars with several winters.

Rattling around the rear silencers from the exhaust flaps (Porsche 718 Cayman GT4 RS and Spyder RS)Exhaust and emissions

Engine / equipment: Porsche 718 Cayman GT4 RS and 718 Spyder RS (982)
Period mentioned: 2024 (US model years)
Symptoms: Rattling or clattering around the rear silencers, mainly on the first start after the car has been parked for a long time.
Possible cause described: The exhaust flap shaft needs some play and can vibrate when it is activated. Porsche replaces the left and right flap actuators with a kit that adds a retaining spring (technical information 287/26).
Check for the garage: Ask the workshop to confirm that the noise comes from the exhaust flaps before fitting the kit from information 287/26.
