Porsche Carrera 4S
Larger turbochargers, more boost pressure, 331 kW in the S and up to 353 kW in the GTS — the DKKA is the workhorse biturbo of the 992 generation with genuine sports car relevance. The character compared to the base DKCA is noticeably sharper: the torque plateau starts earlier, the power build-up is more uncompromising. In the GTS with manual gearbox — available for the first time in the 992 generation in a turbocharged non-GT model — the result is an interesting combination: turbo thrust meets manual engagement. It's no MDG.GA, but it's fun. Mechanically proven, optimised based on 991.2 experience. In the Cabrio with the roof down and sport exhaust, the DKKA sounds distinctly livelier than the specs suggest.
992 C4S — the most complete 911 ever made
The 992 Carrera 4S with PDK is the technically most accomplished all-wheel-drive 911: 331 kW, PDK8, 4WD with electronic control, optional rear-axle steering. As agile as a rear-wheel-drive car on dry roads, unassailable on wet. The 992's electric power steering is finally good enough that you don't miss the hydraulic. Only flaw: the turbo boxer sounds more muted than the naturally aspirated engines of predecessors.
Engine Weaknesses 6
Identical PADM issue from early 992 batches. Higher engine power places greater stress on active mounts. Revised mounts available, engine removal required.
Symptoms: PADM fault warning, increased vibrations, dynamic mount control deactivation
TSB-documented injector issue. On the DKKA, more frequently reproducible under full load conditions with Sport Boost or Launch Control.
Symptoms: Engine stumble under full load, power reduction message, fault codes P0201–P0206, jerk during gear changes
Same ignition coil heat issue as the DKCA. Accelerated wear with spirited driving. Complete set replacement recommended.
Symptoms: Engine stumble, misfire warning, P0301–P0306 OBD codes, power loss
The rear main seal is a known weak point on the DKKA as well. Transmission must be removed for access — combining with PDK service makes sense.
Symptoms: Oil film at transmission input, oil smell, oil drips under the vehicle in rear area
DFI-related deposits on intake valves — across generations. Consider preventive cleaning from 80,000 km.
Symptoms: Power loss, increased fuel consumption, rough running at low RPM
Identical EVAP issue as DKCA — tank vent valve fails early, significant disassembly effort required for access.
Symptoms: Check engine light, fuel system micro-leak fault code, no driveability impact
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.
