The Audi DKAB is a 1,984 cc, inline — four turbocharged petrol engine produced between 2022 and 2023. It belongs to the EA888 Gen 4 engine family, featuring gasoline particulate filter (GPF), direct fuel injection (FSI), variable valve timing (VVT), and an integrated exhaust manifold. In standard configuration, it delivers 169 kW (230 PS) and 370 Nm of torque, meeting stringent Euro 6d emissions standards with real — driving emissions (RDE) certification.
Fitted to mode…
All DKAB engines comply with Euro 6d (RDE) standards , including real-driving emissions certification.
The Audi DKAB is a 1,984 cc inline-four turbocharged petrol engine developed for high-performance compact and mid-size Audi platforms (2022–2023). It integrates gasoline particulate filter (GPF) technology and 48V mild-hybrid support to meet Euro 6d emissions standards. Designed for responsive performance and urban efficiency, it balances modern emissions control with driver engagement.

The Audi DKAB was used across Audi's 8Y/B9.5 platforms with longitudinal mounting and shared with Volkswagen Group brands under modular engine strategy. This engine received platform-specific adaptations-integrated 48V MHEV in A4 and revised GPF housing in Q3-and from 2022 the facelifted 8Y A3 adopted updated ECU mapping for improved cold-start emissions, creating software compatibility limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The DKAB is generally robust when maintained properly, though early builds (2022-2023) show elevated HPFP wear if oil changes are delayed. Later models feature improved fuel pump revisions. Regular oil changes with VW 502 00-compliant 5W-30 oil and adherence to 15,000 km service intervals significantly improve longevity. Well-maintained examples regularly exceed 120,000 km without major issues.
The most documented issues are HPFP actuator wear, GPF clogging, turbo wastegate actuator failure, and timing chain tensioner wear. These are covered in Audi SIB 61-18-01 and field service reports. GPF issues are common in urban drivers with short trips, while HPFP wear is linked to oil quality and service intervals.
The DKAB was used in the Audi A3 (8Y), A4 (B9.5), and Q3 (FY) from 2022 to 2023. It was offered as the 45 TFSI and 45 TFSI MHEV variant and is part of the EA888 Gen 4 family. It is longitudinally mounted and paired with either front-wheel or quattro drive systems depending on model. Some A4 variants include 48V mild-hybrid (MHEV) technology.
Aftermarket ECU tuning is common on the DKAB platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In combined driving, the DKAB achieves approximately 7.4–8.2 L/100 km (38–34 mpg UK). Highway efficiency is better at ~6.7 L/100 km (~42 mpg UK), while city driving may reach 9.8 L/100 km (~29 mpg UK). MHEV-equipped models improve urban economy by up to 0.8 L/100 km through torque-fill and regenerative braking.
Yes, the DKAB is an interference engine. If the timing chain fails or jumps, piston-to-valve contact will occur, resulting in severe internal engine damage. Immediate attention to any timing-related noises or faults is essential to prevent costly repairs.
Audi specifies SAE 5W-30 oil meeting VW 502 00 (petrol) or 505 00 (diesel) standards. Use of approved synthetic oil and adherence to 15,000 km or annual service intervals is critical for turbo, HPFP, and timing system longevity.
