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.

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.

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.
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 DKZA is generally robust when maintained properly, but pre-2021 models are prone to intake valve carbon buildup. Later revisions with updated ECU mapping show improved resistance. Regular oil changes with VW 508 00 oil, intake cleaning every 60,000 km, and use of premium fuel are essential for longevity. The timing chain is designed for life but should be monitored for tensioner wear.
Key issues include intake valve carbon buildup, turbo wastegate rattle, high-pressure fuel pump wear, and GPF clogging. These are documented in Audi TSB 2020-063 and TIS service procedures. Fuel quality, oil type, and driving patterns significantly influence failure rates. Preventive maintenance is critical for long-term reliability.
The DKZA 2.0 TFSI 190 PS was used in the Audi A3 (8Y, 2019–2023), A4 (B9, 2019–2023), and Q3 (2019–2023). It is also found in Volkswagen Golf GTI, Škoda Octavia RS, and SEAT Leon Cupra under the EA888 evo4 engine family designation, all meeting Euro 6d-TEMP standards.
Aftermarket ECU tuning is common on the DKZA 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.
Good for a performance petrol engine. In an A3 2.0 TFSI, combined consumption is ~6.8 L/100km (41.5 mpg UK). Highway driving achieves ~5.9 L/100km (48.0 mpg), while city driving is ~8.0 L/100km (35.3 mpg). Real-world figures typically range 35–45 mpg UK depending on driving style and condition. Premium fuel (RON 98) is recommended for optimal efficiency and power.
Yes. The DKZA is an interference engine. If the timing chain fails or jumps, pistons will contact open valves, causing severe internal damage. While the chain is designed for life, tensioner failure can occur. Any rattling on cold start should be investigated immediately to prevent catastrophic engine damage.
Audi specifies VW 508 00 / 509 00 (SAE 0W-20) low-SAPS synthetic oil. This ultra-low viscosity formulation ensures rapid oil flow at startup, protecting the turbo and variable valve timing system. Change every 15,000 km or annually to maintain engine health and prevent sludge or coking.
