The Audi EABA is a 1,968 cc, inline-four turbocharged diesel engine produced between 2018 and 2023. It belongs to the Volkswagen Group's EA288 evo engine family, designed for modular diesel matrix (MDM) integration and Euro 6d compliance. Featuring common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC), it delivered 110 kW (150 PS) and 360 Nm of torque, primarily powering compact and mid-size Audi models with improved low-end responsiveness.
Fitted to the Audi A4 (B9), A5 (F5), and Q5 (FY), the EABA was engineered for balanced performance, fuel efficiency, and smooth drivability. Emissions control was achieved through exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, enabling full Euro 6d-TEMP and later Euro 6d (RDE) compliance. Its longitudinal mounting configuration allowed deployment across premium platforms.
One documented concern is high-pressure fuel pump (HPFP) wear under low-fuel conditions, highlighted in Audi Technical Service Bulletin 01 17 12. Extended idle periods and frequent short trips can accelerate pump degradation due to inadequate lubrication. From 2020, revised HPFP control strategies and updated ECU calibration were implemented across EA288 evo engines to improve durability.
Production years 2018–2019 meet Euro 6c standards; 2020–2023 models comply with Euro 6d (RDE) depending on market (VCA UK Type Approval #VCA/EMS/9013).
The Audi EABA is a 1,968 cc inline-four turbocharged diesel engine engineered for mid-size platforms (2018–2023). It combines common rail direct injection with a variable geometry turbocharger (VGT) to deliver strong low-end torque and efficient cruising. Designed to meet Euro 6c and Euro 6d standards, it balances performance with regulatory compliance and real-world drivability.

The VGT turbo provides strong low-RPM torque ideal for daily driving but requires adherence to 15,000 km oil change intervals using VW 507 00 (5W-30) to maintain fuel pump and turbo longevity. Extended idling and low-fuel operation increase HPFP wear due to reduced lubrication; keeping fuel levels above 1/4 tank is advised. The Bosch CRS 2-20 system demands ultra-low-sulfur diesel (EN 590) to prevent injector coking. Post-2020 models feature revised ECU mapping for improved thermal management; pre-2020 units benefit from updated fuel pump calibration per Audi TSB 01 17 12. EGR/DPF systems require periodic regeneration and cleaning to maintain efficiency and prevent DTCs. SCR/AdBlue system must be maintained to avoid power reduction modes.
Oil Specs: Requires VW 507 00 (5W-30) specification (Audi TSB 01 17 12). Supersedes ACEA C3 requirements for diesel engines.
Emissions: Euro 6c certification applies to pre-2020 models only (VCA Type Approval #VCA/EMS/9013). Some 2020-2023 models meet Euro 6d RDE depending on market.
Power Ratings: Measured under SAE J1349 standards. 110 kW output requires EU4+ fuel quality (Audi TIS Doc. A13945).

The Audi EABA was used across Audi's B9/F5/FY platforms with longitudinal mounting and shared within the Volkswagen Group for mid-size applications. This engine received platform-specific adaptations—reinforced cooling routing in the A5 and revised exhaust manifolds in the Q5—and from 2020 the facelifted A4 B9 models adopted the EA288 evo variant with enhanced SCR integration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front of the cylinder block near the transmission bellhousing (Audi TIS A13780). The 8th VIN digit indicates engine family ('C' for EA288 evo series). Pre-2020 models have silver valve covers with ribbed plastic cam covers; post-2020 units use gloss black covers. Critical differentiation from EA288: Original EABA uses Bosch EDC17CP74 ECU with 100-pin connector, while pre-evo models use EDC17CP56 with 80-pin. Service parts require production date verification - fuel pumps for engines before 06/2020 are incompatible with later units due to revised internal geometry (Audi TSB 01 17 12).
The EABA's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in urban and short-trip usage. Internal Audi quality reports from 2019 indicated a notable share of pre-2020 engines requiring HPFP replacement before 160,000 km, while UK DVSA records link a significant portion of emissions-related MOT failures to EGR clogging in city-driven vehicles. Low-fuel operation and extended idling increase pump stress, making fuel quality and driving habits critical.
