On the 2018-2025 Porsche 718 Boxster, eU-spec (and later global) 718 four-cylinder cars fitted with a gasoline particulate filter (German: Ottopartikelfilter/OPF) have suffered premature clogging and outright filter failure. Owners report engine-management warning lights, restricted performance/limp mode, and increased fuel consumption. The CAN-bus-monitored exhaust flap/sensor setup can trigger a fault and limp mode if not detected. Documented EU cases include a 2019 Cayman 718 needing GPF replacement at only ~17,000 miles, with quotes around £5,800+VAT, often disputed under warranty because filters are excluded as wear items. Short-trip driving (which prevents passive regeneration) and incorrect-spec oil (e.g. A40 instead of the required C-spec low-ash oil) accelerate the problem. The OPF also reportedly increases turbo lag and restricts the engine on so-equipped cars.
Common Symptoms
Check engine / engine-management warning light
Limp mode / restricted performance
Increased fuel consumption
Turbo lag / sluggish throttle response
How to Fix
Drive the car periodically at sustained highway speed/load to allow the GPF to passively regenerate; avoid repeated short trips. Use only the manufacturer-specified low-ash (C-spec) engine oil. If limp mode or a GPF fault appears, scan for codes and have the filter/differential-pressure sensor inspected; a clogged filter may require forced regeneration or replacement. Pursue a goodwill/warranty claim for premature (low-mileage) failures.
On the 2017-2025 Porsche 718 Boxster, as the 718 ages and heat-cycles, multiple engine seals tend to weep oil. Common leak points are the rear main seal (RMS, between engine and transmission), the valve cover gaskets, and the spark plug tube seals. Symptoms include an oily film/drips under the car, oil residue on the spark plugs and ignition coils, and a burning-oil smell. Oil on the plugs/coils can eventually cause misfires. The rear main seal in particular is a well-known Porsche flat-engine weak point (carried over from earlier Boxster/Cayman/996/997 platforms) and is labor-intensive because transmission removal is required to access it.
Common Symptoms
Oil drips or oily film under the car
Oil residue on spark plugs and coils
Burning oil smell
Misfire from oil-fouled plugs
Smoke from oil on hot exhaust
How to Fix
Clean suspected areas, then short-drive and re-inspect to pinpoint the source. Valve-cover and spark-plug-tube seals are the easiest to address and should be done at major services. A confirmed rear main seal leak requires transmission removal — often combined with a clutch job on manual cars to save labor. Also check oil cooler and cam seals as secondary culprits.
On the 2017-2025 Porsche 718 Boxster, the air-oil separator (crankcase breather/oil separator) on the turbocharged flat-four 718 can fail, causing excessive crankcase vacuum that draws engine oil into the intake. Owners report white/blue smoke (especially at startup or under acceleration), an oil smell, fouled spark plugs, and fuel-trim/check-engine faults. In severe cases the failing AOS has drawn paper-filter debris and oil that blocked the variable-cam (VarioCam) oil passages, requiring major engine teardown. Track-driven cars are especially prone because the stock unit cannot handle the load, risking oil ingestion that can hydro-lock or damage a cylinder.
Diagnose with a crankcase-vacuum test; replace the failed AOS and clean the intake tract. Inspect spark plugs, oxygen sensors and MAF for oil contamination. For track use, consider an upgraded/baffled AOS or catch-can setup. Address promptly to prevent oil-ingestion damage to cams, pistons or sensors.

On the 2017-2025 Porsche 718 Boxster, the 718 Boxster turbo flat-four engines exhibit an annoying wastegate rattle at idle and low RPM. The wastegate actuator arm has slight play that creates a metallic tapping or buzzing sound. While not mechanically harmful, it is a widespread complaint and detracts from the ownership experience.
Porsche released an updated wastegate actuator with tighter tolerances. Some owners report success with adjusting the wastegate arm preload. The rattle does not cause mechanical damage but can be addressed under warranty.
Owner tips & cautions
TipDocument the rattle with a video and bring it to your Porsche dealer — many dealers have replaced the wastegate actuator under warranty. The updated part number resolves the issue.

On the 2017-2025 Porsche 718 Boxster, the engine-driven coolant pump on the turbocharged flat-four 718 (shared design lineage with the 991.2 911) is a known weak point. The pump's bearing wears prematurely and the plastic impeller can degrade or shed, leading to coolant leaks, whining/knocking noise from the pump, and erratic coolant temperature behavior. A failing internal seal can also draw coolant into the engine's vacuum/changeover-valve circuit during warmup. Many owners report failures or proactive replacement around 30,000-40,000 miles (roughly 50,000-65,000 km), well before a coolant pump should normally need service. This is mechanically distinct from external coolant leaks at the turbo connections.
Common Symptoms
Pink or orange coolant puddle under engine
Whining or knocking noise from pump
Coolant smell
Erratic or rising coolant temperature gauge
Low coolant warning
How to Fix
Inspect the water pump for weeping/bearing play and listen for whine; replace the pump (often with the thermostat) proactively at around 30k-40k miles or at the first sign of a leak/noise. Confirm coolant is not being pulled into the vacuum/changeover-valve system. Use only Porsche-approved coolant and bleed the system properly after replacement to avoid air pockets and overheating.
On the 2017-2025 Porsche 718 Boxster, the 718 Boxster convertible top can develop alignment issues causing wind noise at highway speeds and water leaks during rain or car washes. The top latching mechanism can also become misaligned, preventing proper sealing. Some owners report the top motor slowing down in cold weather.
Adjust the convertible top alignment and latch mechanism per Porsche specifications. Replace worn or compressed top seals. Lubricate the latching mechanism and hinges with Porsche-specified lubricant. In cold climates, warm the car briefly before operating the top.
Owner tips & cautions
TipApply 303 Aerospace Protectant to the convertible top seals every 6 months to keep them supple and prevent cracking — this is cheap insurance against water leaks.

On the 2017-2025 Porsche 718 Boxster, the PCM infotainment system in the 718 frequently mishandles Apple CarPlay and at times the touchscreen itself. Owners report the touchscreen becoming unresponsive after a few minutes (audio/maps keep playing but touch input is dead), CarPlay refusing to connect or taking several minutes to appear, and Bluetooth hijacking the interface so wired CarPlay never initializes. The problem is intermittent and a fix that works on one car or one day may not work the next.
Common Symptoms
Touchscreen stops responding after a few minutes
Apple CarPlay won't connect or drops out
Long delay before CarPlay appears
Bluetooth interferes with wired CarPlay
How to Fix
Reboot the PCM by holding the left head-unit (volume) knob until it restarts. To resolve the wired-CarPlay/Bluetooth conflict, 'forget' the Porsche Bluetooth pairing on the iPhone so wired CarPlay can take over the UI. Start the car, wait a moment, then connect an undamaged genuine Apple cable to an unlocked phone (no USB adapter). Apply any available PCM/software updates from the dealer.
