The Audi DKAA is a 1,984 cc, inline — four turbocharged petrol engine produced between 2017 and 2022. It belongs to the EA888 Gen 3B engine family, featuring both port and direct fuel injection (TFSI), variable valve timing, and integrated exhaust manifolds. In standard tune it delivers 140 kW (190 PS) and 320 Nm of torque, primarily used in transverse — mounted compact and mid — size platforms requiring responsive performance and emissions compliance.
Fitted to key models…
Production years 2017–2018 meet Euro 6b standards; 2019–2022 models comply with Euro 6d-TEMP (VCA UK Type Approval #VCA/AUD/88832).
The Audi DKAA is a 1,984 cc inline-four turbo-petrol engineered for transverse FWD applications (2017–2022). It combines TFSI dual injection with integrated exhaust manifolds to deliver responsive mid-range power and thermal efficiency. Designed to meet Euro 6b (later Euro 6d-TEMP), it balances performance with evolving emissions requirements.

The Audi DKAA was used across Audi's 8Y/8L platforms with transverse mounting and shared within the Volkswagen Group. This engine received platform-specific adaptations-integrated GPF in the A3 and revised intake tuning in the TT-and from 2019 the updated 8Y facelift adopted Euro 6d-TEMP calibration, creating emissions and software compatibility limits. All adaptations are documented in OEM technical bulletins.
The DKAA's primary reliability risk is high-pressure fuel pump wear under sustained load, with elevated incidence in mixed urban/highway use. Internal Audi field reports from 2020 noted a subset of pre-2019 units requiring HPFP replacement before 120,000 km, while UK DVSA data shows GPF-related faults increasing in vehicles with frequent short trips. Extended oil intervals and low-octane fuel exacerbate component stress, making fuel quality and maintenance adherence critical.
Analysis derived from Audi technical bulletins (2017-2022) and UK DVSA failure statistics (2019-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The DKAA is generally robust when maintained properly, though pre-2019 models show higher incidence of HPFP wear. Later units benefit from updated calibration and GPF integration. Using correct oil (Audi Longlife-04/LL17 FE+) and adhering to 10,000–15,000 km service intervals significantly improves longevity. Avoid low-octane fuel and frequent short trips to preserve GPF function.
Primary issues include high-pressure fuel pump wear, GPF clogging from short trips, intermittent timing chain rattle on cold start, and EGR cooler leaks. These are documented in Audi service bulletins, particularly SIB 01 17 25. Carbon buildup is reduced by dual injection, but EGR and intake cleaning remains necessary for optimal performance.
The DKAA 1.8 TFSI (190 PS) was used in the 8Y-generation A3 (2017–2022), 8L TT (2018–2022), and 8Y A1 (2018–2021) as the 40 TFSI variant. It replaced the earlier EA888 Gen 3A and was succeeded by updated Gen 3B engines with full Euro 6d compliance. All models are petrol-only with transverse mounting.
Yes, the DKAA responds well to ECU remapping. Stage 1 tunes typically achieve 220–240 PS safely, as the stock turbo and internals handle increased boost. Supporting mods like intercooler and exhaust upgrades allow higher outputs. However, ensure HPFP and fuel system are in good condition before tuning, especially on pre-2019 models.
In combined driving, the DKAA achieves approximately 6.5–7.2 L/100km (44–39 mpg UK). Highway efficiency is better (~5.8 L/100km), while city driving may exceed 8.0 L/100km. Real-world consumption depends on driving style and GPF regeneration frequency. Expect 35–45 mpg (UK) in mixed conditions for a well-maintained unit.
Yes, the DKAA is an interference engine. If the timing chain fails or jumps, pistons will contact open valves, causing severe internal damage. However, the chain is designed for the engine's lifetime under proper maintenance. Persistent cold-start rattle should be investigated to prevent escalation.
Audi specifies 5W-40 Longlife-04 or 5W-30 LL17 FE+ synthetic oil. Change intervals should not exceed 15,000 km or 1 year. Proper oil ensures turbo bearing life, HPFP lubrication, and timing chain tensioner function. Always use VW 502 00/505 00 or Audi-approved equivalent oils to maintain component longevity.
