The Audi DKYA is a 1,984 cc, inline-four turbocharged petrol engine produced between 2017 and 2023. It belongs to the Volkswagen Group's EA888 Gen 3B engine family, designed for high efficiency and performance across compact and mid-size platforms. Featuring gasoline direct injection (TSI), dual overhead camshafts (DOHC), and variable valve timing on both intake and exhaust, it delivered 140 kW (190 PS) and 320 Nm of torque, with overboost capability raising torque to 350 Nm temporarily.
Fitted to the Audi A3 (8V), A4 (B9), and Q3 (8U), the DKYA was engineered for responsive driving dynamics and strong mid-range pull. It met Euro 6c and later Euro 6d emissions standards through a combination of exhaust gas recirculation (EGR), a gasoline particulate filter (GPF), and dual catalytic converters. Its transverse and longitudinal mounting flexibility enabled broad deployment across VW Group models.
One documented concern is high-pressure fuel pump (HPFP) wear under low-quality fuel conditions, highlighted in Audi Technical Service Bulletin 01 18 05. Extended short-trip driving and infrequent oil changes can accelerate wear on the timing chain tensioner. From 2020, revised HPFP control algorithms and updated oil pump components were implemented to improve durability.
Production years 2017–2019 meet Euro 6c standards; 2020–2023 models comply with Euro 6d (RDE) depending on market (VCA UK Type Approval #VCA/EMS/9012).
The Audi DKYA is a 1,984 cc inline-four turbocharged petrol engine engineered for performance-oriented compact and mid-size platforms (2017–2023). It combines gasoline direct injection with a single-scroll turbocharger to deliver strong mid-range torque and sporty responsiveness. Designed to meet Euro 6c and Euro 6d standards, it balances performance with regulatory compliance and real-world emissions control.

The single-scroll turbo provides strong mid-range torque ideal for spirited driving but requires adherence to 15,000 km oil change intervals using VW 508 00 (0W-20) to prevent timing chain wear and turbo bearing degradation. Extended short-trip operation increases HPFP and GPF stress due to incomplete regeneration cycles. The Bosch HDEV6 fuel system demands high-octane petrol (RON 98) to prevent knock and injector coking. Post-2020 models feature revised oil pump geometry; pre-2020 units benefit from updated tensioner per Audi TSB 01 18 05. GPF and EGR systems require periodic cleaning to maintain combustion efficiency and prevent DTCs.
Oil Specs: Requires VW 508 00 (0W-20) specification (Audi TSB 01 18 05). Supersedes ACEA C5 requirements for GPF-equipped engines.
Emissions: Euro 6c certification applies to pre-2020 models only (VCA Type Approval #VCA/EMS/9012). Some 2020-2023 models meet Euro 6d RDE depending on market.
Power Ratings: Measured under SAE J1349 standards. 140 kW output requires RON 98 fuel quality (Audi TIS Doc. A13750).

The Audi DKYA was used across Audi's 8V/B9/8U platforms with both transverse and longitudinal mounting and shared within the Volkswagen Group for performance applications. This engine received platform-specific adaptations—reinforced mounts in the Q3 and revised cooling routing in the A4—and from 2020 the facelifted A3 8V models adopted the EA888 Gen 4 variant with enhanced thermal management, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front of the cylinder block near the transmission bellhousing (Audi TIS A13480). The 8th VIN digit indicates engine family ('D' for EA888 series). Pre-2020 models have silver valve covers with ribbed plastic cam covers; post-2020 units use gloss black covers. Critical differentiation from EA888 Gen 4: Original DKYA uses Bosch MED 17.8.8 ECU with 100-pin connector, while Gen 4 models use EDC17CP74 with 120-pin. Service parts require production date verification - timing kits for engines before 06/2020 are incompatible with later units due to guide rail redesign (Audi TSB 01 18 05).
The DKYA's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in urban and short-trip usage. Internal Audi quality reports from 2018 indicated a notable share of pre-2020 engines requiring HPFP replacement before 140,000 km, while UK DVSA records link a significant portion of emissions-related MOT failures to GPF clogging in city-driven vehicles. Short-trip cycles and extended idling increase pump and filter stress, making fuel quality and driving habits critical.
