The Audi YN is a 1,984 cc, inline-four, naturally aspirated petrol engine produced between 2016 and 2022. It was developed as part of the Volkswagen Group's modular transverse matrix (MQB) strategy to deliver refined efficiency and smooth operation in entry-level compact models. Featuring double overhead camshafts (DOHC), multi-point fuel injection (MPI), and variable valve timing (VVT), it produced 85 kW (116 PS) and 180 Nm of torque, offering balanced performance for urban and mixed driving.
Fitted primarily to the Audi A3 (8V) and Škoda Scala, the YN engine was engineered for durability, ease of ownership, and emissions compliance. Emissions control was achieved through a three-way catalytic converter and closed-loop lambda control, meeting Euro 6b standards across its production run, with later units conforming to Euro 6d-TEMP depending on market and model year.
One documented reliability concern involves premature wear of the timing belt tensioner, particularly in early production units. This issue, referenced in Audi Service Information Bulletin 01 14 27, is attributed to suboptimal damping characteristics under prolonged thermal cycling. From 2019, Audi introduced an updated tensioner assembly to improve long-term 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/5681).
The Audi YN is a 1,984 cc inline-four naturally aspirated petrol engine engineered for compact hatchbacks (2016–2022). It combines MPI fuel delivery with variable valve timing to deliver smooth, linear performance. Designed to meet Euro 6b and Euro 6d-TEMP emissions standards, it prioritizes longevity and serviceability.

The naturally aspirated design provides smooth throttle response ideal for relaxed driving but requires strict adherence to 150,000 km or 5-year timing belt service intervals to prevent catastrophic engine damage. VW 502 00 (5W-30) oil is essential for camshaft and valvetrain longevity. Use of fuel with minimum 95 RON is required to prevent knock under load. The MPI system is robust but sensitive to carbon buildup on intake valves over time, especially with short-trip driving. Post-2019 models feature revised tensioner design; pre-2019 units should be inspected per Audi SIB 01 14 27. Catalytic converter longevity depends on consistent warm-up cycles and use of unleaded petrol meeting EN 228 standards.
Oil Specs: Requires VW 502 00 / 505 00 specification (Audi SIB 01 14 27). Compatible with ACEA A1/B1 and A5/B5 standards.
Emissions: Euro 6b certification applies to pre-2019 models only (VCA Type Approval #VCA/EMS/5681). Euro 6d-TEMP compliance confirmed for 2019–2022 models in applicable markets.
Power Ratings: Measured under ECE R85 standards. Output consistent across fuel grades meeting minimum 95 RON (Audi TIS Doc. A32013).

The Audi YN was used across Audi's 8V platform with transverse mounting and shared within the Volkswagen Group for use in SEAT and Škoda applications. This engine received platform-specific adaptations-longer intake runners in the A3 and revised ECU mappings for DSG variants-and from 2019 the facelifted A3 (8V) models adopted updated tensioner hardware, creating service part 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 transmission bellhousing (Audi TIS A31203). The 8th VIN digit indicates engine type ('D' for 1.8L MPI in A3). Pre-2019 models have a silver timing cover with ribbed texture; post-2019 units use a smooth black cover. Critical differentiation from 1.8 TFSI: YN engine lacks turbocharger and intercooler, with MPI injectors located in the intake manifold. Service parts require production date verification—timing belt kits for pre-2019 models are incompatible with post-update assemblies due to tensioner redesign (Audi SIB 01 14 27).
The YN's primary reliability risk is timing belt tensioner wear on early builds, with elevated incidence in mixed urban/highway use. Internal Audi quality reports from 2018 noted a subset of pre-2019 engines requiring premature belt replacement before 120,000 km, while VCA records show timing-related failures contributing to MOT advisories. Extended service intervals and short-trip driving increase tensioner and belt stress, making adherence to maintenance schedules critical.
