The Audi CZVC is a 1,968 cc, inline-four turbo-diesel engine produced between 2010 and 2018. It belongs to the Volkswagen Group's EA288 engine family, engineered for improved efficiency, reduced emissions, and enhanced durability over its EA189 predecessor. Featuring common rail direct injection, variable geometry turbocharging (VGT), and a DOHC 16-valve layout, it delivers 105 kW (143 PS) and 320 Nm of torque, with advanced combustion control enabling smoother operation and lower particulate output.
Fitted to models such as the A3 (8V), A4 (B8/B9), Q5, and Škoda Superb, the CZVC was designed to meet stringent Euro 5 and later Euro 6 emissions standards. It integrates exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection in certain variants. The engine's modular diesel system (MDP) allows for flexible integration across transverse and longitudinal platforms.
One documented concern involves high-pressure fuel pump (CP4) wear when operated with low-lubricity diesel fuel. This issue is addressed in Audi Technical Service Bulletin 2015-089, which recommends use of EN 590 diesel meeting ISO 12156-1 lubricity standards. From 2014, revised pump calibration and updated ECU mapping were implemented to enhance reliability under real-world conditions.
Production years 2010–2015 meet Euro 5 standards; 2015–2018 models comply with Euro 6d-TEMP (VCA UK Type Approval #VCA/EMS/6789).
The Audi CZVC is a 1,968 cc inline-four turbo-diesel engineered for compact and mid-size platforms (2010–2018). It combines common-rail direct injection with a variable-geometry turbocharger and modular aftertreatment (EGR, DPF, SCR) to deliver responsive performance and regulatory compliance. Designed for Euro 5 and Euro 6 applications, it balances refinement with efficiency.

The VGT provides strong low-RPM torque ideal for urban driving but demands adherence to 15,000 km oil change intervals using VW 504 00/507 00 oil to prevent EGR and DPF clogging. The Bosch CP4 high-pressure pump requires EN 590 diesel with adequate lubricity to avoid premature wear. Timing belt replacement is critical at 150,000 km or 5 years—neglect risks interference damage. SCR-equipped models require regular AdBlue replenishment to maintain emissions compliance and prevent power limitation. Post-2014 models benefit from updated pump calibration per Audi TSB 2015-089, reducing failure risk.
Oil Specs: Requires VW 504 00 / 507 00 specification (Audi TIS Doc. A36215). Supersedes ACEA B4/C3.
Emissions: Euro 5 applies to 2010–2015 models; Euro 6d-TEMP applies to 2015–2018 units (VCA Type Approval #VCA/EMS/6789).
Power Ratings: Measured under SAE J1349 standards. Output consistent across markets with ULSD (EN 590) (Audi Group PT-2021).

The Audi CZVC was used across Audi's 8V/B8/B9 platforms with transverse mounting and shared within the Volkswagen Group for longitudinal applications. This engine received platform-specific adaptations-shorter intake manifolds in the A3 and revised EGR routing in the A4-and from 2014 updated fuel calibration to address pump reliability, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front of the cylinder block, near the timing belt cover (Audi TIS A36215). The 8th VIN digit indicates engine type ('B' for 2.0 TDI EA288 family). Pre-2014 models use a Bosch CP4.1 pump; post-2014 units have revised calibration and updated ECU mapping. Critical differentiation from other EA288 variants: CZVC has 320 Nm torque rating and specific ECU mapping (04L 907 113). Service parts require model-year verification—timing belts for pre-2015 A3s differ from B9 A4 applications (Audi TIS A36215).
The CZVC's primary reliability risk is high-pressure fuel pump wear, with elevated incidence in urban-driven vehicles with frequent short trips. Internal Audi field reports from 2016 indicated a significant share of pre-2014 pumps failing before 180,000 km, while UK DVSA records show increased EGR-related failures in stop-start traffic. Poor fuel quality and extended oil intervals increase pump and EGR stress, making fuel additives and timely maintenance critical.
