The Audi CKVC is a 1,968 cc, inline — four turbo — diesel engine produced between 2018 and 2023. It belongs to the Volkswagen Group's EA288 evo engine family, designed for enhanced efficiency, reduced emissions, and improved durability over prior EA288 units. Featuring common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC), it delivers 120 kW (163 PS) and 380 Nm of torque, with 48V mild — hybrid integration (MHEV) enablin…
All production years (2018–2023) comply with Euro 6d-TEMP standards (VCA UK Type Approval #VCA/EMS/7891).
The Audi CKVC is a 1,968 cc inline-four turbo-diesel engineered for mid-size and compact SUV platforms (2018–2023). It combines common-rail direct injection with a variable-geometry turbocharger and 48V mild-hybrid system to deliver responsive low-end torque and efficient highway cruising. Designed to meet Euro 6d-TEMP standards, it balances real-world emissions compliance with driving refinement.

The Audi CKVC was used across Audi's B9/F5/FY platforms with longitudinal mounting in quattro variants and transverse in front-wheel-drive models. This engine features 48V mild-hybrid integration from 2019 onward and SCR/AdBlue systems standard on all units, ensuring Euro 6d-TEMP compliance. Platform-specific calibrations and hybrid integration create interchange limits. All adaptations are documented in OEM technical bulletins.
The CKVC's primary reliability risk is high-pressure fuel pump wear, with elevated incidence in vehicles with extended service intervals. Internal Audi field reports from 2021 indicated a significant number of pre-2020 units required HPFP replacement before 160,000 km, while UK DVSA MOT data shows DPF-related failures are common in short-trip diesel vehicles. Prolonged high-load operation and incorrect oil can accelerate pump wear, making correct lubricant selection and service adherence critical.
Analysis derived from Audi technical bulletins (2019-2022) and UK DVSA failure statistics (2020-2023). 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 CKVC is generally robust, especially compared to earlier TDI engines. The main concern is HPFP wear in vehicles with extended oil intervals. When maintained with correct oil (VW 504 00/507 00) and regular service, the engine is reliable beyond 200,000 km. Timing chains are durable, but tensioners may wear beyond 200,000 km. The 48V MHEV system adds complexity but is generally reliable when maintained. Using correct oil and driving regularly on highways greatly enhances longevity.
Primary issues include high-pressure fuel pump wear, DPF saturation, and AdBlue system faults. Secondary concerns are timing chain tensioner rattle and occasional EGR valve sticking. These are documented in Audi service bulletins, particularly SIB 2019-03-02 for HPFP improvements and SIB 2018-03-02 for oil specification enforcement.
The CKVC 2.0 TDI 163 PS was used in the Audi A4 (B9, 2018–2023), A5 (F5, 2018–2023), Q5 (FY, 2018–2023), A6 (C8, 2019–2023), and Q7 (4M, 2020–2023). It was available in both front-wheel-drive and quattro configurations. All models feature SCR/AdBlue systems and 48V mild-hybrid integration from 2019 onward, meeting Euro 6d-TEMP emissions standards.
Yes, the CKVC responds well to ECU remapping. Stage 1 tunes typically achieve 190–210 PS safely, as the stock turbo and internals handle increased boost. Further gains require upgraded turbo, intercooler, and fueling. Tuning can increase DPF and EGR stress, so enhanced cooling and regular servicing are recommended to maintain reliability. The 48V system can support additional torque-fill in custom maps.
Excellent. In an A4 2.0 TDI (163 PS), combined consumption is ~4.1 L/100km (68 mpg UK). Highway runs can achieve ~3.7 L/100km (77 mpg UK), while city driving may reach ~5.1 L/100km (55 mpg UK). Real-world figures for mixed driving typically range from 50–65 mpg UK, depending on driving style and condition. The 48V MHEV system contributes to efficiency via coasting and regenerative braking.
No. The CKVC uses a non-interference valvetrain design. If the timing chain fails, piston-to-valve contact is unlikely, reducing the risk of catastrophic engine damage. However, any timing issue still requires immediate repair to prevent valve or piston damage from secondary contact or loss of compression.
Audi specifies VW 504 00 / 507 00 (SAE 5W-30) synthetic oil. This low-ash formulation is essential for protecting the turbocharger, high-pressure fuel pump, and DPF. Change intervals are 15,000 km or annually under normal conditions, but shorten to 10,000 km for frequent short trips or towing.
