Porsche Turbo
3.8 litres, two turbochargers, 580 hp — and the engine communicates exactly that. The DKEA sits lower in the rev range than a naturally aspirated engine, but the power delivery is broad and consistent. Technically closely related to the DKCA/DKKA, but with larger displacement and higher-spec turbochargers. The typical 992 platform issues of the early production years (PADM engine mounts, water pump) affect the Turbo too. Special attention goes to the fuel injectors: documented per TSB MC-10249857-0001 — under overboost or launch control, defective injectors can trigger limp mode. Ignition coil failure is a cross-generational topic; for track use, preventive coil replacement is recommended. Monitor the rear crankshaft seal under the high torque loads long-term.
992 Turbo Cabrio — hypercar in the open
As a convertible the 992 Turbo remains brutally fast and takes on a slightly more relaxed character. Open, the 3.8-litre biturbo sounds more distinct; the AWD safety allows full confidence on any surface. For drivers who don't need a roof but want full turbo punch.
Engine Weaknesses 6
Early 992 Turbo vehicles (production year 2020) had the same water pump manufacturing weakness as the Carrera range. Revised pumps provided as warranty replacements.
Symptoms: Coolant temperature warning, coolant loss without visible external leakage
The DKEA is also affected by the PADM sealing issue from early 992 production. Revised mounts available, replacement requires engine removal.
Symptoms: PADM fault message on dashboard, noticeable vibration increase, adaptive engine mount deactivation
Ignition coil failure due to thermal stress occurs earlier on the DKEA due to higher power demands. Particularly during track use and Sport Boost operation.
Symptoms: Misfires at high RPM, engine power reduction warning under full load, P0301–P0306
Injector defect documented per Porsche TSB MC-10249857-0001 — particularly noticeable with the overboost function active. Limp mode after launch control.
Symptoms: Engine power reduced — visit workshop, misfire at full load, limp mode, fault codes P020100/P020400
High torque values (750 Nm+) of the 992 Turbo put greater long-term stress on the rear crankshaft seal. Transmission removal required for access.
Symptoms: Oil film at rear of engine, oil smell, oil drips in rear area, PDK fluid may become contaminated
DFI-related intake valve deposits also affect the 3.8L biturbo. Preventive cleaning from around 80,000 km is worth considering.
Symptoms: Power loss, slight rough running at low rpm, elevated fuel consumption
Vehicle Weaknesses 9
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 complex Targa mechanism locks up in wet or cold weather. The rear lid opens, the latches release, but the roof does not travel back. Workshop lubrication usually fixes it permanently.
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.
The thermally sealed fold lines roughen up relatively quickly. Never stow a wet roof, and re-treat regularly with protectant. The issue is known from the 991 generation and has not been fully resolved.
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.
Wind noise can occur around the seals at high speeds. Readjustment and silicone treatment help. Significantly quieter than the predecessor, but not at coupé level.
