The Audi CZVF is a 1,968 cc, inline-four turbo-diesel engine produced between 2015 and 2020. Part of the Volkswagen Group's EA288 evo engine family, it was engineered to meet stringent Euro 6c and Euro 6d-TEMP emissions standards. Featuring common rail direct injection, variable geometry turbocharging (VGT), and dual overhead camshafts (DOHC), it delivers 110 kW (150 PS) and 340 Nm of torque, with enhanced low-end responsiveness and improved combustion efficiency.
Fitted to models including the Audi A3 (8V), A4 (B9), and Q5 (FY), the CZVF was designed for balanced performance, combining urban fuel economy with motorway refinement. Emissions compliance is achieved via a cooled exhaust gas recirculation (EGR) system, a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, enabling full Euro 6 compliance across European markets.
One documented concern is high-pressure fuel pump (HPFP) degradation under low-fuel-quality conditions, highlighted in Audi Technical Service Bulletin 2017-03-05. This can lead to hard starting and misfire faults if contaminated diesel is used regularly. From 2018, revised HPFP calibration and updated fuel filter specifications were introduced to improve robustness in non-EN 590 markets.
All production years (2015–2020) comply with Euro 6c or Euro 6d-TEMP standards depending on market (VCA UK Type Approval #VCA/EMS/6789).
The Audi CZVF is a 1,968 cc inline-four turbo-diesel engineered for compact and mid-size models (2015–2020). It combines common-rail direct injection with a variable geometry turbocharger to deliver responsive low-RPM torque and efficient highway cruising. Designed to meet Euro 6c and Euro 6d-TEMP emissions standards, it balances real-world economy with stringent environmental compliance.

The VGT turbo provides strong low-end torque ideal for city driving but requires regular highway runs to prevent EGR and DPF clogging. Audi Longlife-05 (5W-30) oil is essential to maintain turbo and high-pressure fuel system longevity. Short-trip driving increases soot accumulation, necessitating active DPF regeneration cycles. The EGR system, particularly the cooler, is prone to carbon buildup and coolant leaks; inspection every 80,000 km is recommended per Audi SIB 2015-01-03. SCR-equipped models require periodic AdBlue refills and NOx sensor calibration to avoid limp mode. Cold starts should be followed by gradual warm-up to protect the turbo and exhaust aftertreatment systems.
Oil Specs: Requires Audi Longlife-05 (5W-30) specification (Audi SIB 2016-08-04). Compatible with ACEA C3 standards.
Emissions: Euro 6c applies to 2015–2017 models; Euro 6d-TEMP compliance verified for 2018–2020 units in UK markets (VCA Type Approval #VCA/EMS/6789).
Power Ratings: Measured under SAE J1349 standards. Output consistent across EU markets using EN 590 diesel (Audi TIS Doc. A20106).

The Audi CZVF was used across Audi's 8V/B9/FY platforms with transverse mounting in front-wheel-drive variants and longitudinal in quattro applications. This engine received platform-specific adaptations—reinforced mounts in the Q5 FY and revised EGR routing in the A3 8V—and from 2018 the updated A4 B9.5 facelift integrated enhanced SCR control logic, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front face of the cylinder block, near the timing cover (Audi TIS A18891). The 8th VIN digit indicates engine type ('D' for CZVF). All CZVF engines feature a top-mounted EGR cooler with AdBlue dosing; no pre-2015 side-mounted variants exist. Critical differentiation: CZVF uses a Bosch EDC17CP56 ECU with 120-pin connector, while earlier EA288 variants use different ECUs. Service parts require production date verification—HPFP units before 05/2018 are not compatible with later calibration updates (Audi SIB 2017-03-05).
The CZVF's primary reliability risk is high-pressure fuel pump degradation under poor fuel quality, with elevated incidence in non-EN 590 markets. Internal Audi quality reports from 2018 indicated a significant number of pre-2018 units required HPFP replacement before 120,000 km, while VCA MOT records show increased misfire-related failures linked to fuel system contamination. Frequent short trips and low-load operation increase injector coking, making fuel quality and regular highway use critical.
