The Audi CTVA is a 1,968 cc, inline — four turbo — diesel engine produced between 2018 and 2023. 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 emissions standards through a combination of exhaust gas recirculation (EGR), diesel particulate filter (DPF), and selective ca…
Production years 2018–2023 meet Euro 6d standards .
The Audi CTVA is a 1,968 cc inline-four turbo-diesel engine engineered for mid-size and premium models (2018–2023). 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 standards, it balances performance with real-world emissions compliance.

The Audi CTVA 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 2020 the facelifted A4 models adopted the updated DPF monitoring system, 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 CTVA delivers strong torque and good efficiency, but early models (2018-2019) had reliability concerns, especially DPF regeneration issues. Later revisions (post-2020) improved DPF 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 DPF regeneration failure (leading to limp mode), turbo actuator sticking, and AdBlue system faults. Other complaints include 48V MHEV BAS unit failures and occasional EGR valve issues. 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 2.0 TDI and 40 TDI trims. It was also shared across the Volkswagen Group in VW Passat (2.0 TDI) from 2019-2023. In all cases, the engine met Euro 6d emissions standards.
Aftermarket ECU tuning is common on the CTVA 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 2.0 TDI (2020), typical consumption is ~5.6 L/100km (city) and ~4.0 L/100km (highway), or about 57 mpg UK combined. Real-world figures vary, but expect 50-60 mpg (UK) on mixed roads for a healthy CTVA 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.
