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 highway performance.
Fitted to models including the Audi A4 (B9), A5 (F5), and Q5 (FY), the CKVD engine was engineered for balanced driving dynamics and compliance with Euro 6d emissions standards. It achieves certification through a combination of exhaust gas recirculation (EGR), diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, allowing it to meet EU Regulation (EC) No 715/2007 and subsequent Real Driving Emissions (RDE) requirements.
One documented reliability improvement is the revised high-pressure fuel pump (HPFP) design introduced in 2019 per Audi Service Information Bulletin 2019-03. This update addressed wear patterns in the HPFP drive mechanism by enhancing internal material hardness and lubrication pathways. The CKVD also features an integrated exhaust manifold within the cylinder head to improve warm-up times and reduce thermal stress on turbocharger components.
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 CKVD's integrated exhaust manifold enables faster warm-up and improved low-RPM torque delivery, ideal for urban driving, but demands adherence to 15,000 km oil change intervals using VW 504 00/507 00 oil to protect the HPFP and turbocharger. The Bosch CRS 2-20 fuel system requires ultra-low-sulfur diesel (EN 590) to prevent injector and pump wear. Timing belt replacement is critical at 150,000 km or 6 years; post-2019 models benefit from revised HPFP design per Audi SIB 2019-03, improving long-term reliability. SCR-equipped variants require periodic AdBlue refills and must complete regular highway drives to maintain DEF system functionality. EGR and DPF systems need active regeneration cycles; short-trip driving may necessitate forced regens to prevent clogging.
Oil Specs: Requires VW 504 00 / 507 00 specification (Audi SIB 2019-03). Compatible with ACEA C3.
Emissions: Euro 6c applies to 2018–2020 models; Euro 6d certification confirmed for 2021–2023 units (VCA Type Approval #VCA/EMS/9123).
Power Ratings: Measured under SAE J1349 standards. Output consistent across EU markets with EN 590 diesel (Audi TIS Doc. A32200).

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.
Locate the engine code stamped on the front of the cylinder block near the timing belt cover (Audi TIS A32200). The 8th VIN digit indicates engine type ('C' for EA288 evo series). Pre-2021 models use Euro 6c emissions with DPF-only; post-2021 units feature full Euro 6d compliance with SCR and AdBlue tank. Critical differentiation from EA288 variants: CKVD has integrated exhaust manifold in cylinder head and revised HPFP with enhanced lubrication. Service parts require production date verification—timing belts for pre-2019 models are not compatible with post-2019 revisions due to tensioner redesign (Audi SIB 2019-03).
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.
