The Audi CYPA is a 1,968 cc, inline-four turbo-diesel engine produced between 2016 and 2022. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts (DOHC). In standard output configurations, it delivers 110 kW (150 PS) and 360 Nm of torque, with higher outputs available in tuned variants.
Fitted to models such as the A3 (8V), A4 (B9), A6 (C8), and Q5 (FY), the CYPA was engineered for improved fuel efficiency, reduced emissions, and enhanced low-end torque. Emissions compliance was achieved via exhaust gas recirculation (EGR), a diesel particulate filter (DPF), and selective catalytic reduction (SCR) with AdBlue injection, meeting strict Euro 6b and Euro 6d-TEMP standards.
One documented reliability concern is high-pressure fuel pump (HPFP) wear, particularly on early-build units. This issue, referenced in Audi Service Bulletin 2017-08-05 (Audi SIB 2017-08-05), is linked to fuel quality sensitivity and inadequate lubrication under ultra-low-sulfur conditions. From 2018, revised pump internals and updated fuel system calibration were implemented to improve durability.

Production years 2016–2018 meet Euro 6b standards; 2019–2022 models comply with Euro 6d-TEMP depending on market (VCA UK Type Approval #VCA/EMS/9012).
The Audi CYPA is a 1,968 cc inline-four turbo-diesel engineered for compact and mid-size models (2016–2022). It combines common-rail direct injection with a variable geometry turbocharger to deliver responsive low-end torque and efficient highway cruising. Designed to meet Euro 6 emissions standards, it balances performance with economy across Audi's diesel lineup.

The CYPA provides strong low-RPM torque ideal for urban and highway driving, but requires adherence to 15,000 km oil change intervals using Audi Longlife 04 (5W-30) to maintain fuel pump and turbo longevity. The Bosch HPFP is sensitive to fuel quality, necessitating ultra-low-sulfur diesel (ULSD) meeting EN 590 standards to prevent premature wear. EGR, DPF, and SCR systems require regular regeneration and periodic cleaning to avoid flow restrictions and limp mode. Early CYPA units (pre-2018) should be inspected for HPFP wear; updated pumps and calibration revisions post-2018 improved reliability. Cold-start idling should be minimized to reduce EGR soot accumulation.
Oil Specs: Requires Audi Longlife 04 (5W-30) specification (Audi SIB 2017-08-05). Supersedes ACEA C3 and meets VW 505.01 requirements.
Emissions: Euro 6b certification applies to pre-2019 models only (VCA Type Approval #VCA/EMS/9012). Euro 6d-TEMP compliance confirmed for 2019–2022 builds in EU markets.
Power Ratings: Measured under SAE J1349 standards. 140 kW output requires EU3+ fuel quality and revised ECU calibration (Audi TIS Doc. A20154).

The Audi CYPA was used across Audi's 8V/B9/C8 platforms with longitudinal mounting. This engine received platform-specific adaptations-shorter intake manifolds in the A3 and revised cooling routing in the Q5-and from 2019 the facelifted A4 B9.5 adopted updated emissions calibration with SCR integration, 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 A18754). The 8th VIN digit indicates engine type ('C' for CYPA series). Pre-2018 models have silver valve covers with black plastic intake manifolds; post-2018 units use black valve covers. Critical differentiation from later EA288 engines: CYPA uses Bosch CRS 2-20 fuel system with round fuel rail access port, while EA288 uses CRS 3-20 with flat access. Service parts require production date verification—HPFP units before 12/2017 are incompatible with post-2018 calibrations due to internal revisions (Audi SIB 2017-08-05).
The CYPA's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in regions with inconsistent fuel quality. Internal Audi quality reports from 2018 noted a significant share of pre-2018 units requiring pump replacement before 150,000 km, while UK DVSA records show EGR/DPF clogging contributes to a notable portion of emissions-related MOT failures in city-driven vehicles. Extended idling and short trips increase soot accumulation, making regular regeneration and maintenance critical.
