The Audi CCZA is a 1,968 cc, inline-four turbo-diesel engine produced between 2012 and 2018. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard tune, it delivers 85 kW (116 PS) and 250 Nm of torque, designed for efficient urban and regional driving in Audi's compact and mid-size models.
Fitted to models such as the A1 (8X), A3 (8V), and Q3 (8U), the CCZA engine was engineered for cost-effective ownership and low emissions. Emissions compliance was achieved via exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and in later models, selective catalytic reduction (SCR) with AdBlue injection, enabling Euro 5 compliance (2012–2015) and Euro 6b compliance (2015–2018) depending on model year and market.
One documented reliability concern is high-pressure fuel pump (HPFP) wear, highlighted in Audi Technical Service Bulletin 2014-16-02. Premature wear is linked to extended service intervals and inconsistent fuel quality. From 2015, revised fuel system calibration and updated injector control strategies were implemented to improve durability in Euro 6 variants.

Production years 2012–2015 meet Euro 5 standards; 2015–2018 models comply with Euro 6b depending on market (VCA UK Type Approval #VCA/EMS/5679).
The Audi CCZA is a 1,968 cc inline-four turbo-diesel engineered for compact and mid-size models (2012–2018). It combines common-rail direct injection with a variable geometry turbocharger to deliver responsive low-end torque and efficient city driving. Designed to meet Euro 5 and Euro 6b standards, it balances economy with regulatory compliance.

The CCZA provides strong low-end torque ideal for urban driving, but requires strict adherence to 15,000 km oil change intervals using Audi Longlife-05 (5W-30) oil to ensure timing chain and turbo longevity. The Bosch CRS 2.0 fuel system demands ultra-low-sulfur diesel (EN 590) to prevent HPFP wear. EGR and DPF systems require regular long-distance driving to prevent clogging. Post-2015 Euro 6 models include SCR with AdBlue injection, necessitating periodic tank refills. Cold starts should be minimized to reduce thermal stress on the turbo and EGR cooler.
Oil Specs: Requires Audi Longlife-05 (5W-30) specification (Audi SIB 2012-08-03). Supersedes ACEA B4 and C3 standards.
Emissions: Euro 5 applies to 2012–2015 models; Euro 6b certification for 2015–2018 units (VCA Type Approval #VCA/EMS/5679).
Power Ratings: Measured under ECE R85 standards. Output remains consistent across markets; no derating observed in hot climates (Audi TIS Doc. A35012).

The Audi CCZA was used across Audi's 8X/8V/8U platforms with transverse mounting in front-wheel-drive models. This engine received platform-specific adaptations—reinforced engine mounts in the Q3 (8U) and revised intake manifolds in the A1 (8X)—and from 2015 the Euro 6 update introduced SCR and AdBlue injection, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block near the timing cover (Audi TIS A35012). The 8th VIN digit indicates engine type ('C' for CCZA series). Pre-2015 models have a silver valve cover with a black plastic intake; post-2015 units feature a black valve cover and integrated AdBlue dosing module. Critical differentiation from EA288 engines: CCZA uses a Bosch CRS 2.0 fuel system and lacks a dual-loop EGR system. Service parts require model-year verification—DPF and EGR components pre- and post-2015 are not interchangeable due to SCR integration (Audi SIB 2015-06-02).
The CCZA's primary reliability risk is high-pressure fuel pump wear, with elevated incidence in urban-driven vehicles with short trips. Internal Audi quality reports from 2015 noted increased HPFP failures in units with oil change intervals exceeding 15,000 km, while UK DVSA data links a significant share of emissions-related MOT failures to EGR/DPF clogging. Frequent cold starts and low-quality diesel exacerbate fuel system stress, making fuel quality and service adherence critical.
