The Audi DDTA is a 1,968 cc, inline — four turbo — diesel engine produced between 2018 and 2023. It belongs to the Volkswagen Group's EA288 evo engine family, designed for high efficiency, low emissions, and long — term durability. Featuring common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC), it delivers 85 kW (116 PS) and 250 Nm of torque, optimized for urban efficiency and light — load responsiveness.
Fitted to models…
Production years 2018–2019 meet Euro 6d-TEMP standards; 2020–2023 models comply with Euro 6d depending on market .
The Audi DDTA is a 1,968 cc inline-four turbo-diesel engineered for compact and mid-size models (2018–2023). It combines common-rail direct injection with a variable-geometry turbocharger to deliver responsive low-RPM torque and efficient urban driving. Designed to meet Euro 6d-TEMP and Euro 6d emissions standards, it balances economy with environmental compliance.

The Audi DDTA was used across Audi's 8V/B9/F3 platforms with transverse mounting in front-wheel-drive models and longitudinal in quattro variants. This engine received platform-specific adaptations-shorter intake manifolds in the A3 and revised cooling layouts in the Q3-and from 2020 the facelifted A4 B9.5 adopted the updated EA288 evo2 variant with enhanced SCR dosing, 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 DDTA delivers solid efficiency and reliability, but early models (2018–2019) had concerns with fuel injector coking. Later revisions (post-2020) improved durability with updated injectors and calibration. Well-maintained engines with regular oil changes using Audi Longlife-18 (0W-30) can exceed 200,000 km. Adherence to service intervals is critical for long-term reliability.
The most documented issues are fuel injector coking, turbo actuator sticking, EGR and intake carbon buildup, and oil leaks from valve/timing covers. These are confirmed in Audi service bulletins and field reports. Regular maintenance significantly reduces the risk of major failures.
The DDTA engine was used in the A3 (8V), A4 (B9), and Q3 (F3) models from 2018 to 2023. It was available in 25 TDI and 30 TDI trims, primarily in European markets. Euro 6d-TEMP models were produced until 2019, with Euro 6d variants from 2020 onward.
Aftermarket ECU tuning is common on the DDTA 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.
Excellent. In an A3 25 TDI (8V), real-world consumption averages ~4.8 L/100km (city) and ~3.9 L/100km (highway), or ~58 mpg UK combined. A4 and Q3 variants show similar efficiency. Expect 55–60 mpg UK on mixed driving with proper maintenance.
Yes. The DDTA is an interference engine. If the timing chain fails or jumps, pistons can strike open valves, resulting in severe internal damage. Immediate attention to any chain rattle or warning lights is essential to prevent catastrophic engine failure.
Audi specifies SAE 0W-30 oil meeting Longlife-18 standards. Use only VW 504 00 or Audi-approved synthetic oil and change every 15,000 km or annually. Proper oil ensures injector protection and maintains chain lubrication.
