The Audi CHVA is a 1,798 cc, inline-four turbocharged petrol engine produced between 2014 and 2019. It belongs to the Volkswagen Group's EA888 Gen 3 engine family, designed for improved efficiency, performance, and emissions compliance. Featuring direct fuel injection (TSI), variable valve timing (AVS), and dual overhead camshafts (DOHC), it delivers 132 kW (180 PS) and 250 Nm of torque, offering responsive driving dynamics and strong mid-range pull.
Fitted to models including the A3 (8V), A4 (B8/B9), and Q3, the CHVA was engineered for a balance of sportiness and fuel economy. Its compact design allows transverse mounting across multiple platforms, with features such as thermal management via an electro-mechanical coolant pump and cylinder-on-demand technology in certain applications. Emissions compliance is achieved through a three-way catalytic converter and lambda control, meeting Euro 6 standards.
One documented reliability concern is high-pressure fuel pump (HPFP) wear, particularly under sustained high-load conditions. This issue, referenced in Audi Service Information Bulletin 2016-021, is linked to mechanical stress on the pump's internal drive components. From 2016 onward, revised pump assemblies and updated ECU calibrations were introduced to improve durability and reduce failure rates.
All production years (2014–2019) meet Euro 6 emissions standards (VCA UK Type Approval #VCA/EMS/7891).
The Audi CHVA is a 1,798 cc inline-four turbocharged petrol engine engineered for compact and mid-size platforms (2014–2019). It integrates TSI direct injection with a single-scroll turbocharger to deliver responsive performance and efficient fuel consumption. Designed to meet Euro 6 emissions standards, it balances sporty character with regulatory compliance through advanced thermal and fuel management.

The CHVA's turbocharging and AVS system provide strong low-end torque and smooth power delivery, ideal for spirited driving and motorway cruising. VW 502 00/505 00 oil is essential for turbo and HPFP longevity due to its thermal stability. Fuel quality is critical—premium unleaded (98 RON) is recommended for sustained performance. The timing chain requires no scheduled replacement but should be inspected if rattle or oil consumption issues arise. Post-2016 models feature updated HPFP design and revised ECU mapping to reduce wear and improve throttle response.
Oil Specs: Requires VW 502 00 / 505 00 specification (Audi SIB 2015-010). Not compatible with ACEA A/B standards.
Emissions: All models comply with Euro 6 standards (VCA Type Approval #VCA/EMS/7891). No Euro 5 variants exist.
Power Ratings: Measured under SAE J1349. Output assumes premium fuel (98 RON) and ambient conditions (Volkswagen Group PT-2015).

The Audi CHVA was used across Audi's 8V/B8/B9 platforms with transverse mounting and shared within the Volkswagen Group for longitudinal and transverse applications. This engine received platform-specific adaptations—reinforced engine mounts in the Q3 and revised intake manifolds in the A3—and from 2016 the facelifted B9 A4 adopted updated HPFP and ECU calibration, 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 belt cover (Audi TIS A36820). The 8th VIN digit indicates engine type ('C' for 2.0 TFSI EA888 series). Pre-2016 units have silver valve covers; post-2016 models use black. Critical differentiation from CHVB: CHVA has Bosch HDP5 HPFP with square electrical connector, while CHVB uses revised pump with trapezoidal connector. Service parts require production date verification—HPFP and ECU from pre-2016 models are not compatible with post-facelift B9 units due to calibration changes (Audi SIB 2016-021).
The CHVA's primary reliability risk is high-pressure fuel pump degradation, with elevated incidence in mixed urban/highway use. Internal Audi quality reports from 2017 noted increased HPFP failure rates in pre-2016 builds, while UK DVSA MOT data links a significant portion of emissions-related failures to lambda sensor and catalytic converter faults in stop-start traffic. Extended service intervals and low-octane fuel amplify fuel system stress, making fuel quality and maintenance adherence critical.
