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 op…
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 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.
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.
Analysis derived from Audi technical bulletins (2010-2018) and UK DVSA failure statistics (2015-2023). 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 CZVC is generally robust when maintained properly, but pre-2014 models are prone to high-pressure fuel pump wear. Later revisions with updated CP4.2 pumps show improved durability. Regular oil changes with VW 504 00 oil, EGR cleaning, and strict timing belt adherence (150,000 km/5 years) are essential for longevity.
Key issues include Bosch CP4 fuel pump failure, EGR valve/coolant clogging, timing belt degradation, and turbo actuator sticking. These are documented in Audi TSB 2015-089 and TIS service procedures. Fuel quality and maintenance intervals significantly influence failure rates.
The CZVC 2.0 TDI 143 PS was used in the Audi A3 (8V, 2010–2018), A4 (B8/B9, 2010–2018), and Q5 (2010–2017). It is also found in Volkswagen Passat B8, Škoda Superb Mk3, and SEAT Exeo under the EA288 engine family designation, meeting Euro 5 and Euro 6 standards.
Yes. The CZVC responds well to ECU remapping, with stage 1 tunes safely achieving 170–180 PS. The stock turbo and internals support moderate increases. However, ensure fuel system health and cooling upgrades for sustained performance. Tuning should not exceed 190 PS without mechanical reinforcement.
Excellent. In an A3 2.0 TDI, combined consumption is ~4.1 L/100km (69 mpg UK). Highway driving can achieve ~3.7 L/100km (77 mpg), while city driving is ~4.8 L/100km (59 mpg). Real-world figures typically range 55–70 mpg UK depending on driving style and condition.
Yes. The CZVC is an interference engine. If the timing belt fails or jumps, pistons will contact open valves, causing severe internal damage. This makes strict adherence to the 150,000 km or 5-year replacement interval absolutely critical.
Audi specifies VW 504 00 / 507 00 (SAE 5W-30) synthetic oil. This low-SAPS formulation protects the EGR, DPF, SCR, and turbo while ensuring proper timing belt tensioner lubrication. Change every 15,000 km or annually to maintain engine health.
