Engine
— Half the factory interval, filter cut open every time — mid-engine cars hide their leaks and their evidence, so the filter is where we read the engine's mood.Book an appointment →
— The book is right — and on the turbo flat-four each electrode gets read as a health report for its cylinder.Book an appointment →
— Startup smoke on a flat engine is the AOS speaking — the crankcase vacuum reading settles it in five minutes.Book an appointment →
Cooling
— Fresh coolant is cheap insurance for aluminum and pumps alike.Book an appointment →
— Same nose, same appetite for leaves as the 911 — an hour of clean-out saves the radiators.Book an appointment →
— The weep shows on inspection long before the gauge moves — we look every visit.
Transmission
— Same PDK truth as the 911: half the factory interval is the cheapest respect you can pay it.Book an appointment →
— Gear oil is the cheapest synchro repair there is.Book an appointment →
Brakes
— These cars get driven the way Porsche intended more often than most — tracked cars get fluid annually, full stop.Book an appointment →
Suspension
— A mid-engine chassis this precise makes one soft bushing feel like four — a hands-on check finds it before you learn to drive around it.
Engineering notes
Known issues on this platform
Front radiator & condenser corrosion
Debris packs the nose intakes and eats the coolers from outside in — the platform's most preventable big bill.
Radiator clean-out & inspection
AOS fatigue — startup smoke
Cold-start smoke and fouled plugs mean the air-oil separator, not the rings. Vacuum test first, always.
AOS vacuum test & replacement
PDK on the "lifetime" myth
Fluid age, not design, behind most PDK complaints — serviced at 60k it simply works.
PDK clutch & gear oil service
Coolant fittings & hoses with age
Plastic quick-connects harden with heat cycles; a pressure test during service finds tomorrow's leak while it's a clamp and an O-ring.
