Porsche Carrera
The DKCA is the consistent evolution of the MA2 — same 3.0-litre biturbo architecture, but with GPF particulate filter and slightly revised boost control. Early vehicles from the first production year 2019 had structural manufacturing issues: the active engine mounts (PADM) were insufficiently sealed — water ingress destroys the sensor. Porsche provided revised mounts, but replacement requires engine removal. Second known weakness of early batches: water pump failure at very low mileages. From model year 2021 both problems are largely eliminated. The ignition coil issue is cross-generational — heat stress from the rear-mounted position; replacing all six coils at once is recommended. Mechanically solid otherwise, provided the service history is complete.
Carrera 4 — all-year sobriety
AWD takes the last bit of rear dynamics away from the 992 Carrera. Clearly recommendable as an all-weather, very safe sports car. As an emotional experience, the most sober 911 in the range. Nothing wrong, but nothing exciting.
Engine Weaknesses 6
Early 992 production batches (late 2019, early 2020) had faulty water pumps. Porsche supplied revised pumps as warranty replacements.
Symptoms: Coolant temperature rise, coolant warning light, coolant loss without external leakage on very early vehicles
On early 992 models (2019–2020) the active powertrain damper mounts (PADM) were not sufficiently sealed at the factory. Water enters the mount internals and destroys the sensor.
Symptoms: PADM fault warning on the dashboard, increased vibration in the cabin, system disables dynamic mount control
9A2 engine ignition coils fail from long-term heat exposure — particularly cylinders 1 and 4 due to their proximity to the exhaust. Replace all six coils together.
Symptoms: Engine stumble, start-stop deactivated, engine control fault, misfire (OBD: P0301–P0306)
Individual injectors leave the factory faulty — documented in a Porsche TSB. Repair is carried out by replacing the affected injector individually.
Symptoms: Engine stumble under medium load, engine reduction warning, occasional power dip at full throttle
The 992 fuel tank vent valve can fail early and triggers a check engine light with an EVAP leak code. Access requires considerable disassembly effort.
Symptoms: Check engine light (CEL), fuel system micro-leak fault code, occasional clicking at low rpm
Like all DI flat-six engines without port injection, the DKCA gradually builds up deposits on the intake valves. Preventive cleaning from around 80,000–100,000 km can be worthwhile.
Symptoms: Power loss, elevated fuel consumption, occasional rough running — only noticeable at higher mileages
Vehicle Weaknesses 6
Software fault on 8,666 vehicles: the hazard lights do not activate reliably during emergency braking. Free software update at the dealer.
Early build years 2019/2020: windscreen not correctly bonded, water enters the footwell. Repaired under warranty.
The PCM 5.0 infotainment system freezes on the Porsche logo or restarts spontaneously. Driver profiles are also not correctly restored after restart. Often fixable via software.
The active engine mounts (PADM, Sport Chrono) lose their damping function due to sensor failure. In 98% of cases only the internal sensor is faulty — full mount replacement is not needed.
Door cards, dashboard area and parcel shelf creak and rattle over bumps. Several owners report build quality inadequate for the price segment.
Known noise source: the steering rack cover contacts the steering linkage and produces a creaking sound. Porsche has issued an official service bulletin for this.
