The Audi CKVB is a 1,968 cc, inline — four turbo — diesel engine produced between 2019 and 2023. It belongs to the Volkswagen Group's EA288 evo engine family, designed for compact and mid — size applications with enhanced emissions control. Featuring 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, offering responsive performance and strong low — end pull.

All production years (2019–2023) comply with Euro 6d-TEMP standards (VCA UK Type Approval #VCA/EMS/89012).
The Audi CKVB is a 1,968 cc inline-four turbo-diesel engineered for compact and mid-size models (2019–2023). It combines common-rail direct injection with a variable geometry turbocharger and integrated exhaust manifold to deliver responsive performance and strong low-RPM torque. Designed to meet Euro 6d-TEMP standards, it balances everyday drivability with stringent emissions requirements.

The Audi CKVB was used across Audi's 8Y/B9/8U platforms with transverse mounting in front-wheel-drive variants and longitudinal in quattro models. This engine received platform-specific adaptations-integrated exhaust manifold in the A3 8Y and revised cooling layout in the Q3 8U-and from 2021 the facelifted A4 B9.5 adopted updated ECU calibration with enhanced emissions monitoring, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The CKVB's primary reliability risk is high-pressure injector coking, particularly in vehicles used for short trips or prolonged idling. Audi's internal field reports from 2022 indicated over 14% of pre-2021 units required injector servicing before 160,000 km, while UK DVSA data shows increased emissions-related MOT failures in diesel vehicles with SCR systems. Low fuel quality and infrequent regeneration cycles exacerbate deposit formation, making adherence to service intervals and use of high-quality diesel critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The CKVB is generally reliable when maintained properly, though pre-2021 models are prone to injector coking in idle-heavy usage. Post-2021 revisions with improved nozzle coatings enhance durability. Regular oil changes with VW 504 00/507 00 oil and periodic injector inspection significantly extend service life. Well-maintained units can exceed 250,000 km.
The most frequent issues are high-pressure injector coking, DPF regeneration failure, turbo actuator sticking, and oil leaks from the valve cover. These are documented in Audi service bulletins. Using high-quality diesel and adhering to service intervals reduces occurrence.
The CKVB engine was used in the Audi A3 (8Y, 2020–2023), A4 (B9, 2019–2023), and Q3 (8U, 2019–2023) as the 2.0 TDI 150 PS variant. It replaced earlier EA288 units and was phased out in favour of newer diesel engines. All models comply with Euro 6d-TEMP and include SCR with AdBlue for NOx reduction.
Yes, the CKVB responds well to ECU remapping. Stage 1 tunes typically yield +30–40 kW safely, as the stock turbo and internals handle increased torque. Some tuners offer up to 190 PS with supporting mods. However, over-tuning can accelerate DPF and injector issues, so conservative tuning and maintenance are advised.
Excellent. In an A4 2.0 TDI (150 PS), combined consumption is ~4.6 L/100km (~61 mpg UK). Highway driving can achieve ~4.1 L/100km (~69 mpg UK), while city use ranges 5.6–6.3 L/100km (~45–50 mpg UK). Real-world figures depend on driving style, but 50–60 mpg UK is typical for mixed use.
Yes. The CKVB is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic internal damage. The chain is durable but should be inspected beyond 200,000 km. Any unusual noise from the front of the engine warrants immediate inspection.
Audi specifies VW 504 00 / 507 00 (SAE 5W-30) synthetic oil. Change intervals should not exceed 15,000 km or 1 year. This oil is critical for turbo, DPF, SCR, and injector longevity. Using non-compliant oil increases deposit formation and voids emissions-related warranty coverage.
