AUDI DKZA engine (2019–2023) – Specs, Problems & Compatibility Database

The Audi DKZA is a 1,984 cc, inline-four turbocharged petrol engine produced between 2019 and 2023. It belongs to the Volkswagen Group's EA888 evo4 engine family, designed for high efficiency, reduced emissions, and enhanced performance. Featuring direct fuel injection (TSI), variable valve timing, and a twin-scroll turbocharger, it delivers 140 kW (190 PS) and 320 Nm of torque, with intelligent thermal management enabling rapid warm-up and improved fuel economy.

Fitted to models such as the A3 (8Y), A4 (B9), and Q3, the DKZA was engineered for responsive daily driving and sporty character. Emissions compliance is achieved through gasoline particulate filter (GPF), exhaust gas recirculation (EGR), and integrated exhaust manifold, allowing it to meet Euro 6d-TEMP standards across its production run.

One documented concern involves carbon buildup on intake valves due to reliance on direct injection alone. This issue is addressed in Audi Technical Service Bulletin 2020-063, which recommends periodic intake cleaning. From 2021, revised port injector calibration and updated ECU mapping were implemented to mitigate deposit formation under real-world conditions.

Compliance Note:

Production years 2019–2023 meet Euro 6d-TEMP standards (VCA UK Type Approval #VCA/EMS/9012).

DKZA Technical Specifications

The Audi DKZA is a 1,984 cc turbocharged inline-four petrol engine engineered for compact and mid-size platforms (2019–2023). It combines TSI direct injection with an integrated exhaust manifold and twin-scroll turbocharger to deliver strong low-end response and regulatory compliance. Designed to meet Euro 6d-TEMP standards, it balances performance with refinement.

Practical Implications

The twin-scroll turbo provides strong low-RPM torque ideal for urban driving but demands adherence to 15,000 km oil change intervals using VW 508 00/509 00 oil to prevent turbo coking and GPF blockage. The direct injection system requires periodic intake valve cleaning due to lack of fuel wash. Timing chain is designed for life but must be monitored for tensioner wear. Post-2021 models benefit from updated ECU mapping per Audi TSB 2020-063, reducing carbon buildup risk. Use of premium unleaded (RON 98) enhances performance and reduces knock tendency.

Data Verification Notes

Oil Specs: Requires VW 508 00 / 509 00 specification (Audi TIS Doc. A39025). Supersedes ACEA C5.

Emissions: Euro 6d-TEMP certification applies to all DKZA models (2019–2023) (VCA Type Approval #VCA/EMS/9012).

Power Ratings: Measured under SAE J1349 standards. Output consistent across markets with RON 98 fuel (Audi Group PT-2024).

DKZA Compatible Models

The Audi DKZA was used across Audi's 8Y/B9 platforms with transverse mounting. This engine received platform-specific adaptations-shorter intake runners in the A3 and revised cooling routing in the Q3-and from 2021 updated ECU calibration to address carbon buildup, creating interchange limits. All adaptations are documented in OEM technical bulletins.

Identification Guidance

Locate the engine code stamped vertically on the right side of the cylinder block near the exhaust manifold (Audi TIS A39025). The 8th VIN digit indicates engine type ('C' for 2.0 TFSI EA888 evo4 family). Pre-2021 models have standard intake port calibration; post-2021 units feature revised ECU mapping to reduce carbon deposits. Critical differentiation from other EA888 variants: DKZA has 320 Nm torque rating and specific ECU mapping (06E 907 113). Service parts require model-year verification—oil pumps for pre-2020 A3s differ from B9 A4 applications (Audi TIS A39025).

Identification Details

Evidence:

Audi TIS Doc. A39025

Location:

Stamped vertically on the right side of the cylinder block near the exhaust manifold (Audi TIS A39025).

Visual Cues:

  • Pre-2021: Standard intake port design
  • Post-2021: Updated ECU calibration for reduced carbon buildup
Timing Chain

Warning:

Failure is rare but catastrophic if tensioner fails; monitor for rattling on cold start.

Evidence:

Audi TIS Doc. A39025

Interval:

Designed for lifetime service but requires inspection for tensioner wear during major services.
Carbon Buildup

Issue:

Intake valves prone to carbon deposits due to direct injection only (no port injection wash).

Evidence:

Audi TSB 2020-063

Recommendation:

Perform intake valve cleaning every 60,000 km or as symptoms arise (rough idle, misfires).
Fuel Quality

Note:

Lower octane fuel may trigger knock sensors, reducing power output via ECU derating.

Evidence:

Audi TIS Doc. A39025

Requirement:

Premium unleaded (RON 98) recommended for optimal performance and knock prevention.

Common Reliability Issues - AUDI DKZA

The DKZA's primary reliability risk is carbon buildup on intake valves, with elevated incidence in vehicles with frequent short trips. Internal Audi field reports from 2022 indicated a significant share of pre-2021 engines requiring cleaning before 100,000 km, while UK DVSA records show increased misfire-related MOT failures in city-driven examples. Short trip cycles and use of non-OEM oil increase deposit formation, making scheduled maintenance and fuel quality critical.

Intake valve carbon buildup
Symptoms: Rough idle, misfires, reduced power, check engine light, poor cold start behavior.
Cause: Lack of fuel wash over intake valves due to direct injection only; oil vapour ingress via PCV system accelerates deposit formation.
Fix: Perform walnut blasting or chemical cleaning of intake valves; renew PCV system components and update ECU software per Audi TIS A39601.
Turbocharger wastegate rattle
Symptoms: Clicking or rattling noise from turbo at idle or light load, especially when cold.
Cause: Wear or clearance in the turbo wastegate linkage; design allows slight movement that diminishes with age.
Fix: Inspect wastegate actuator and linkage; replace turbo assembly if excessive play or performance issues occur per Audi TIS A39601.
High-pressure fuel pump wear
Symptoms: Hard starting, loss of power, fuel pressure DTCs, ticking noise from top of engine.
Cause: Internal wear due to low lubricity in certain fuels or extended service intervals; high-pressure operation (up to 350 bar) increases stress.
Fix: Replace with updated HDEV6 pump per Audi TSB 2020-063; flush fuel system and verify fuel quality.
Gasoline particulate filter (GPF) clogging
Symptoms: Reduced power, increased fuel consumption, frequent regeneration events, DPF-related DTCs.
Cause: Extended short-trip driving prevents full regeneration; poor fuel quality increases soot loading.
Fix: Enable forced regeneration via diagnostic tool; replace GPF if structural damage or excessive backpressure detected per Audi TIS A39025.
