The Audi CZVD 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). Delivering 105 kW (143 PS) and 320 Nm of torque, it was engineered for refined mid-range performance and improved fuel efficiency over earlier TDI units, meeting Euro 5 and later Euro 6 emissions standards.
Fitted to models such as the A1 (8X), A3 (8V), A4 (B8.5), and Q3 (8U), the CZVD engine was designed for urban and highway versatility, combining responsive low-end torque with quiet operation. Emissions control included exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) in select Euro 6 variants introduced from 2015, ensuring compliance across European markets and UK type approval VCA/EMS/6789.
One documented reliability concern is high-pressure fuel pump (HPFP) wear under extended service intervals, noted in Audi Technical Service Bulletin 2014-18-02. Premature wear was attributed to fuel quality sensitivity and inadequate filtration in early 2012–2014 production. From 2015 onward, Audi implemented revised HPFP sealing and updated fuel system calibration to enhance durability.
Production years 2012–2014 meet Euro 5 standards; 2015–2018 models comply with Euro 6 depending on market (VCA UK Type Approval #VCA/EMS/6789).
The Audi CZVD 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-RPM performance and fuel efficiency. Designed to meet Euro 5 and later Euro 6 emissions standards, it balances drivability with regulatory compliance.

The VGT turbo 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) to ensure longevity of the high-pressure fuel pump and turbocharger. Ultra-low sulfur diesel (ULSD, EN 590) is essential to prevent HPFP wear and injector coking. EGR and DPF systems require regular regeneration; prolonged short trips may lead to clogging and limp mode. Post-2015 models feature revised HPFP and updated ECU calibration, reducing failure incidence. SCR-equipped models (2015+) require AdBlue top-ups and periodic NOx sensor diagnostics.
Oil Specs: Requires Audi Longlife 05 (5W-30) specification (Audi SIB 2014-18-02). Supersedes ACEA B4 and C3 standards.
Emissions: Euro 5 applies to 2012–2014 models (VCA Type Approval #VCA/EMS/6789). Euro 6 certification valid for 2015–2018 depending on market.
Power Ratings: Measured under SAE J1349 standards. Output consistent across fuel qualities due to closed-loop injection control (Audi TIS Doc. A32176).

The Audi CZVD was used across Audi's 8X/8V/B8.5 platforms with transverse mounting and shared architecture with Volkswagen and Škoda applications. This engine received platform-specific adaptations—modified intake routing in the A1 and revised cooling in the Q3—and from 2015 the facelifted A4 B8.5 adopted Euro 6-compliant variants with SCR systems, creating interchange limits. Partnerships allowed Volkswagen's 2.0 TDI CR and Škoda's 2.0 TDI to use identical core architecture. 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 A32176). The 8th VIN digit indicates engine type ('D' for CZVD series). Pre-2015 models have a Bosch CP3 high-pressure fuel pump; post-2015 units use a revised CP3.3 with improved sealing. Critical differentiation from EA288: CZVD uses a single VGT turbo (Garrett GT1749V), while EA288 variants may feature twin-scroll or e-VGT. Service parts require production date verification — fuel pumps and ECU variants differ significantly between 2012–2014 and 2015+ builds (Audi SIB 2014-18-02).
The CZVD's primary reliability risk is high-pressure fuel pump (HPFP) wear in early builds, with elevated incidence in urban driving with frequent short trips. Internal Audi quality reports from 2014 indicated a significant number of pre-2015 units required HPFP replacement before 150,000 km, while UK DVSA MOT data links DPF clogging to stop-start driving in city environments. Poor fuel quality and extended service intervals increase pump and injector stress, making fuel filtration and oil change adherence critical.
