The Audi DLJA is a 1,968 cc, inline — four turbo — diesel engine produced between 2016 and 2022. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). Delivering 140 kW (190 PS) and 400 Nm of torque, it was engineered for strong mid — range performance and improved efficiency, meeting Euro 6 emissions standards across all markets.

All production years (2016–2022) comply with Euro 6d-TEMP emissions standards (VCA UK Type Approval #VCA/EMS/9123).
The Audi DLJA is a 1,968 cc inline-four turbo-diesel engineered for mid-size and premium models (2016–2022). It combines common-rail direct injection with a variable geometry turbocharger to deliver strong low-RPM response and efficient cruising. Designed to meet Euro 6d-TEMP standards, it balances performance with environmental compliance.

The Audi DLJA was used across Audi's B9/F5 platforms with longitudinal mounting and shared architecture with Volkswagen and Škoda applications. This engine received platform-specific adaptations—modified intake routing in the A5 and revised cooling in the Q5—and from 2019 the facelifted A4 B9.5 adopted updated thermal management systems, creating interchange limits. Partnerships allowed Volkswagen's 2.0 TDI CR and Škoda's 2.0 TDI to use identical core architecture. All adaptations are documented in OEM technical bulletins.
The DLJA's primary reliability risk is high-pressure fuel pump (HPFP) wear in early builds, with elevated incidence in aggressive driving with frequent short trips. Internal Audi quality reports from 2018 indicated a significant number of pre-2019 units required HPFP replacement before 150,000 km, while UK DVSA MOT data links DPF clogging to stop-start driving in city environments. Poor fuel quality and extended service intervals increase pump and injector stress, making fuel filtration and oil change adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The DLJA is generally robust when properly maintained, but early models (2016–2018) are prone to high-pressure fuel pump failures. Later revisions (2019+) with updated pumps and calibration show improved reliability. Regular oil changes with Audi Longlife 05 (5W-30) and use of quality diesel (EN 590) are essential for long-term durability.
The most common issues are high-pressure fuel pump wear, turbo actuator sticking, EGR and intake carbon buildup, and oil leaks from the valve cover and turbo lines. These are documented in Audi service bulletins and confirmed by UK MOT failure data, particularly in urban-driven vehicles.
The DLJA engine was used in the Audi A4 (B9), A5 (F5), and Q5 (8W) between 2016 and 2022. It was also shared with Volkswagen (Passat B8) and Škoda (Superb C7). All applications were 190 PS variants with Euro 6d-TEMP compliance and SCR-based NOx reduction.
Yes, the DLJA responds well to ECU remapping. Stage 1 tunes typically achieve 220–230 PS safely, as the stock turbo and internals handle increased boost. However, exceeding 230 PS may stress the HPFP and require supporting upgrades. Tuning should be performed by specialists familiar with ME17/EDC17 ECUs.
In real-world driving, the DLJA achieves approximately 5.6–6.4 L/100km (city) and 4.7–5.2 L/100km (highway). This equates to 44–50 mpg (UK) on mixed routes. Models with SCR and longer gearing (e.g., A4) may achieve slightly better figures. Driving style and DPF regeneration cycles significantly affect consumption.
Yes, the DLJA is an interference engine. If the timing chain fails or jumps, piston-to-valve contact is likely, resulting in severe internal damage. While the chain is generally durable, it should be inspected if noise or performance issues arise, especially on high-mileage engines.
Audi specifies 5W-30 synthetic oil meeting Audi Longlife 05 specification. This oil is critical for HPFP lubrication and turbo bearing protection. Oil changes should occur every 15,000 km or annually, whichever comes first, to maintain fuel system and engine longevity.
