The Audi CVKB is a 1,968 cc, inline — four turbo — diesel engine produced between 2017 and 2021. It belongs to the EA288 Evo engine family, featuring common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard configuration it delivers 110 kW (150 PS) with 360 Nm of torque, offering strong low — end pull and refined efficiency for compact and mid — size models.
Fitted to models including the 8V A3, B9 A4, and 8Y A1, the CVK…
All production years (2017–2021) comply with Euro 6d-TEMP depending on market .
The Audi CVKB is a 1,968 cc inline-four turbo-diesel engine from the EA288 Evo series, designed for compact and mid-size models (2017–2021). It integrates variable geometry turbocharging with common rail injection and dual overhead camshafts to deliver responsive low-RPM torque and improved emissions control. Engineered to meet Euro 6d-TEMP standards, it balances drivability with stringent environmental compliance.

The Audi CVKB was used across Audi's 8V/B9 platforms with transverse mounting and shared within the Volkswagen Group. This engine received platform-specific adaptations-integrated starter-generator (ISG) in mild-hybrid variants and revised cooling in high-performance A4 applications-and from 2019 the facelifted A3 8V adopted updated emissions controls, 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.
The CVKB's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in high-mileage and performance-oriented use. Internal Audi quality reports from 2018 indicated a significant share of pre-2019 engines requiring HPFP replacement before 150,000 km, while VCA MOT data links a portion of fuel system failures to degraded injection timing in urban-driven examples. Frequent high-load operation and poor fuel quality increase pump and cam lobe stress, making fuel specification and maintenance adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The CVKB is generally robust when maintained properly, but early models (2017–2018) are prone to HPFP and timing chain issues. Later revisions (post-2019) improved component durability. Regular use of high-quality diesel (EN 590), correct oil (5W-30 VW 507 00), and adherence to service intervals greatly enhance longevity. Well-maintained units reliably exceed 200,000 km.
Primary issues include high-pressure fuel pump wear due to cam follower lobe degradation, timing chain tensioner failure, and EGR/intake carbon buildup. DPF clogging from short trips and turbo actuator sticking are also reported. These are documented in Audi service bulletins and addressed through revised components from 2019 onward.
The CVKB engine was used in the Audi A3 (8V, 2017–2021), A4 (B9, 2017–2021), and A1 (8Y, 2019–2021) as the 2.0 TDI 150 PS variant. It also appears in Volkswagen Group models like the Mk7.5 Golf. All variants meet Euro 6d-TEMP emissions standards.
Aftermarket ECU tuning is common on the CVKB 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.
In combined driving, expect 4.8–5.6 L/100km (50–59 mpg UK). Highway efficiency improves to ~4.3 L/100km (~65 mpg UK), while city driving may reach 6.3 L/100km (~45 mpg UK). Real-world consumption depends on driving style and route. Start-stop systems in later models improve urban economy.
Yes. The CVKB is an interference engine, meaning a timing failure can result in piston-to-valve contact and severe internal damage. Proper chain maintenance and timely repairs are essential. Any timing-related warning should be addressed immediately to prevent catastrophic engine failure.
Audi specifies SAE 5W-30 oil meeting VW 507 00 (diesel) or 505 00 (multi) standards. Use only ACEA C2/C3 or OEM-approved low-SAPS synthetics. Change oil every 15,000 km or annually to protect the turbo, EGR, and fuel system from wear and coking.
