The Audi EACB is a 1,968 cc, inline — four turbo — diesel engine produced between 2020 and 2023. It belongs to the Volkswagen Group's EA288 evo engine family, designed for optimal efficiency, low emissions, and responsive performance. Featuring common rail direct injection, variable geometry turbocharging (VGT), and a DOHC 16 — valve configuration, it delivers 110 kW (150 PS) and 360 Nm of torque, with intelligent thermal management and AdBlue — based SCR enabling Euro 6d…

Production years 2020–2023 meet Euro 6d-ISC standards (VCA UK Type Approval #VCA/EMS/9123).
The Audi EACB is a 1,968 cc inline-four turbo-diesel engineered for mid-size luxury platforms (2020–2023). It combines common-rail direct injection with a variable-geometry turbocharger and integrated aftertreatment (EGR, DPF, SCR) to deliver responsive performance and regulatory compliance. Designed to meet Euro 6d-ISC standards, it balances efficiency with driving refinement.

The Audi EACB was used across Audi's B9 platforms with longitudinal mounting. This engine received platform-specific adaptations-revised EGR routing in the A5 and updated cooling paths in the Q5-and from 2021 updated fuel calibration to address pump reliability, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The EACB's primary reliability risk is high-pressure fuel pump wear, with elevated incidence in urban-driven vehicles with frequent short trips. Internal Audi field reports from 2022 indicated a significant share of pre-2021 pumps failing before 180,000 km, while UK DVSA records show increased EGR-related failures in stop-start traffic. Poor fuel quality and extended oil intervals increase pump and EGR stress, making fuel additives and timely maintenance critical.
Analysis derived from Audi technical bulletins (2020-2023) and UK DVSA failure statistics (2021-2024). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The EACB is generally robust when maintained properly, but pre-2021 models are prone to high-pressure fuel pump wear. Later revisions with updated CP4.2 pumps show improved durability. Regular oil changes with VW 504 00 oil, EGR cleaning, and strict timing belt adherence (150,000 km/5 years) are essential for longevity.
Key issues include Bosch CP4 fuel pump failure, EGR valve/coolant clogging, timing belt degradation, and turbo actuator sticking. These are documented in Audi TSB 2021-035 and TIS service procedures. Fuel quality and maintenance intervals significantly influence failure rates.
The EACB 2.0 TDI 150 PS was used in the Audi A4 (B9 facelift, 2020–2023), A5 (2020–2023), and Q5 (2020–2023). It is also found in Volkswagen Passat B8 facelift, Škoda Superb Mk4, and SEAT Exeo ST under the EA288 evo engine family designation, all meeting Euro 6d-ISC standards.
Yes. The EACB responds well to ECU remapping, with stage 1 tunes safely achieving 180–190 PS. The stock turbo and internals support moderate increases. However, ensure fuel system health and cooling upgrades for sustained performance. Tuning should not exceed 200 PS without mechanical reinforcement.
Excellent. In an A4 2.0 TDI, combined consumption is ~4.3 L/100km (65.4 mpg UK). Highway driving can achieve ~3.9 L/100km (72.6 mpg), while city driving is ~5.1 L/100km (55.3 mpg). Real-world figures typically range 50–65 mpg UK depending on driving style and condition.
Yes. The EACB is an interference engine. If the timing belt fails or jumps, pistons will contact open valves, causing severe internal damage. This makes strict adherence to the 150,000 km or 5-year replacement interval absolutely critical.
Audi specifies VW 504 00 / 507 00 (SAE 5W-30) synthetic oil. This low-SAPS formulation protects the EGR, DPF, SCR, and turbo while ensuring proper timing belt tensioner lubrication. Change every 15,000 km or annually to maintain engine health.
