The Audi DKTA is a 1,984 cc, inline-four turbocharged petrol engine produced between 2020 and 2023. It belongs to the Volkswagen Group’s EA888 Gen 4 engine family, featuring gasoline direct injection (TSI), a cast-iron block with an aluminium head, and a belt-driven valvetrain. In standard tune it delivers 195 kW (265 PS) with peak torque of 370 Nm available from 1,600 rpm, offering strong mid-range performance ideal for sporty driving.
Fitted to models including the Audi S3 (8V), SQ2 (GA), and TT RS (8S), the DKTA was engineered for high-performance transverse applications requiring responsive power delivery and thermal efficiency. It meets Euro 6d emissions standards through a close-coupled three-way catalyst, gasoline particulate filter (GPF), and dual injection system (direct + port), ensuring compliance while maintaining throttle response and performance.
One documented service update involves revised high-pressure fuel injector calibration to reduce low-speed pre-ignition (LSPI) events, addressed in Audi Technical Service Bulletin 2021-24-01. Early production units exhibited occasional knock sensor activation under high-load conditions. From 2021, Audi implemented updated ECU mapping and revised injector spray patterns, improving combustion stability and reducing long-term carbon accumulation.
All DKTA models comply with Euro 6d (2020–2023) depending on market (VCA UK Type Approval #VCA/EMS/9123).
The Audi DKTA is a 1,984 cc inline-four turbocharged petrol engine engineered for high-performance transverse applications (2020–2023). It combines TSI direct injection with a twin-scroll turbocharger to deliver strong mid-range torque and responsive performance. Designed to meet Euro 6d standards, it balances power delivery with emissions compliance in sport-oriented platforms.

The twin-scroll turbo provides strong low-RPM pull ideal for spirited driving but requires strict adherence to 15,000 km oil change intervals to prevent LSPI and turbo bearing wear. Audi Longlife 05 (5W-30) oil is essential due to its thermal stability and compatibility with GPF and timing belt materials. Extended idling should be avoided to reduce coking in the intake ports. Dual injection reduces carbon buildup compared to direct-only systems, but high-quality fuel meeting EN 228 standards is still required to prevent injector deposits. From 2021, revised ECU maps per Audi TSB 2021-24-01 improve combustion stability and reduce knock events under high load.
Oil Specs: Requires Audi Longlife 05 (5W-30) specification (Audi TSB 2021-24-01). Compatible with ACEA A1/B1.
Emissions: Euro 6d compliance confirmed for all DKTA models (2020–2023) depending on market (VCA Type Approval #VCA/EMS/9123).
Power Ratings: Measured under SAE J1349 standards. Output achieved with 95 RON fuel (Audi TIS Doc. A88810).

The Audi DKTA was used across Audi's 8V/GA platforms with transverse mounting and shared within the Volkswagen Group for high-performance applications. This engine received platform-specific adaptations-tuned throttle response in the S3 and revised cooling circuits in the TT RS-and from 2021 the facelifted 8V.5 revision introduced updated ECU calibration and GPF monitoring, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block near the transmission bellhousing (Audi TIS A88810). The 8th VIN digit indicates engine family ('D' for EA888 petrol). Pre-2021 models have silver valve covers with exposed camshafts; post-2021 units use black covers with integrated breather. Critical differentiation from EA888 2.0 TFSI 195 kW: DKTA uses a high-flow turbo and revised intake manifold. Service parts require production date verification - fuel injectors for pre-2021 models are not compatible with post-2021 revisions due to spray pattern redesign (Audi TSB 2021-24-01).
The DKTA's primary reliability risk is GPF clogging in urban-driven vehicles, with elevated incidence in stop-start city use. Internal Audi quality reports from 2022 indicated a notable share of pre-2021 engines requiring GPF cleaning before 100,000 km, while UK DVSA records show increased emissions-related failures in GPF-equipped models. Frequent short trips and delayed oil changes increase thermal and carbon stress, making driving pattern and service interval adherence critical.
Analysis derived from Audi technical bulletins (2020-2023) and UK DVSA failure statistics (2021-2023). Repair procedures should follow manufacturer guidelines.
