The Audi CVNA is a 1,968 cc, inline — four turbo — diesel engine produced between 2020 and 2025. Part of the Volkswagen Group’s EA288 evo diesel engine family, it features common rail direct injection, variable geometry turbocharging (VGT), and dual overhead camshafts. It delivers 110 kW (150 PS) with 360 Nm of torque, meeting stringent Euro 6d — ISC — FCM emissions standards through a combination of exhaust gas recirculation (EGR), diesel particulate filter (DPF), and sel…
Production years 2020–2025 meet Euro 6d-ISC-FCM standards .
The Audi CVNA is a 1,968 cc inline-four turbo-diesel engine engineered for mid-size and premium models (2020–2025). It combines common rail fuel delivery with variable geometry turbocharging and 48V MHEV integration to deliver responsive torque and improved efficiency. Designed to meet Euro 6d-ISC-FCM standards, it balances performance with real-world emissions compliance.

The Audi CVNA was used across Audi's B9/C8/FY platforms with longitudinal mounting and shared within the Volkswagen Group for transverse applications. This engine received platform-specific adaptations-revised cooling routing in the A6 and integrated MHEV components in the Q5-and from 2022 the facelifted A4 models adopted the updated EGR valve design, 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 CVNA delivers strong torque and good efficiency, but early models (2020-2021) had reliability concerns, especially EGR valve sticking. Later revisions (post-2022) improved EGR durability, so well-maintained examples can be quite robust. Regular servicing, using high-quality oil (5W-30 VW 505 01), and periodic highway runs greatly aid longevity.
The biggest issues are EGR valve sticking (leading to rough idle), turbo actuator sticking, and DPF saturation due to city driving. Other complaints include 48V MHEV BAS unit failures and occasional AdBlue system faults. These are well-documented in Audi service bulletins.
This 2.0L diesel was used in the Audi A4 (B9), A6 (C8), and Q5 (FY) models, primarily in 40 TDI trims. It was also shared across the Volkswagen Group in VW Passat (2.0 TDI) from 2020-2025. In all cases, the engine met Euro 6d-ISC-FCM emissions standards.
Aftermarket ECU tuning is common on the CVNA 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 for a turbo diesel. In an A6 40 TDI (2022), typical consumption is ~5.5 L/100km (city) and ~4.0 L/100km (highway), or about 58 mpg UK combined. Real-world figures vary, but expect 50-60 mpg (UK) on mixed roads for a healthy CVNA engine.
Yes. The EA288 evo series (like most modern Audis) is an interference engine. This means if the timing chain fails, pistons can strike open valves, causing catastrophic engine damage. Chain maintenance is critical—any sign of wear should be addressed immediately.
Audi specifies a 5W-30 synthetic oil meeting VW 505 01 (diesel) or 507 00 (AdBlue-equipped) specification. Change oil every 15,000 km or 2 years to ensure proper lubrication and prevent sludge buildup, especially in urban driving conditions.
