The Audi CKVD is a 1,968 cc, inline — four turbo — diesel engine produced between 2018 and 2023. Part of the Volkswagen Group's EA288 evo engine family, it features advanced emissions control and improved durability over previous EA288 units. Equipped with common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC), it delivers 110 kW (150 PS) and 360 Nm of torque, with enhanced low — end response for responsive urban and highwa…
Production years 2018–2020 meet Euro 6c standards; 2021–2023 models comply with Euro 6d (VCA UK Type Approval #VCA/EMS/9123).
The Audi CKVD is a 1,968 cc inline-four turbo-diesel engineered for longitudinal mid-size platforms (2018–2023). It combines common-rail direct injection with a variable-geometry turbocharger and integrated exhaust manifold to deliver strong torque and improved emissions performance. Designed to meet Euro 6d standards, it balances urban drivability with long-distance refinement and RDE compliance.

The Audi CKVD was used across Audi's B9/F5/FY platforms with longitudinal mounting and shared within the Volkswagen Group for premium applications. This engine received platform-specific calibrations-shorter intake runners in the A4 and revised cooling routing in the Q5-and from 2021 updated RDE calibration for Euro 6d compliance, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The CKVD's primary reliability risk is EGR and DPF clogging in vehicles used for short-trip driving. Internal Audi quality reports from 2021 noted increased EGR valve failures in urban-driven units before 120,000 km, while UK DVSA MOT data shows DPF-related failures as a leading cause of emissions test failures. Cold climates and poor fuel quality amplify system stress, making regular highway runs and fuel additive use critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The CKVD offers strong fuel economy and smooth performance, with improved reliability over earlier EA288 engines. The revised HPFP and Euro 6d emissions system enhance durability, but SCR-equipped models require regular highway driving to maintain AdBlue system health. Strict maintenance, use of quality diesel (EN 590), and adherence to oil and timing belt intervals are essential for long-term reliability.
Key issues include EGR/DPF clogging, timing belt failure, oil leaks from valve cover gaskets, and AdBlue system faults in SCR-equipped models. These are documented in Audi service bulletins, particularly SIB 2019-03 for HPFP improvements. Urban driving exacerbates EGR and DPF issues, while cold climates increase AdBlue-related risks.
The CKVD engine was used in the Audi A4 (B9, 2018–2023), A5 (F5, 2018–2023), Q5 (FY, 2018–2023), and A6 (C8, 2019–2023). It was phased out in favour of updated EA288 evo2 variants with improved emissions and efficiency post-2023.
Yes, the CKVD responds well to ECU remapping. Stage 1 tunes typically achieve 180–190 PS safely. However, increased fuel pressure and turbo boost stress the HPFP and EGR system, so supporting modifications and high-quality maintenance are strongly advised to maintain reliability.
In mixed driving, the CKVD achieves approximately 5.0–5.6 L/100km (50–57 mpg UK). Highway efficiency is around 4.5 L/100km (62 mpg UK), while city driving may reach 6.2 L/100km (46 mpg UK). Real-world figures depend on driving style, vehicle weight, and condition of emissions systems.
Yes, the CKVD is an interference engine. If the timing belt fails, pistons will contact open valves, resulting in severe internal damage. Adhering to the 150,000 km or 6-year replacement interval is critical to avoid costly repairs.
Audi specifies VW 504 00 / 507 00 (SAE 5W-30) synthetic oil. This low-ash formulation is essential for DPF and SCR system protection and HPFP longevity. Oil changes should be performed every 15,000 km or annually to maintain engine health and prevent sludge buildup.
