The Audi 8920 is a 1,984 cc, inline-four petrol engine produced between 2010 and 2016. It features double overhead camshafts (DOHC), multi-point fuel injection, and variable valve timing (VVT), delivering a balance of responsiveness and fuel efficiency. In standard tune, it produces 103 kW (140 PS) with 200 Nm of torque, primarily used in compact and mid-size Audi models.
Fitted to platforms including the Audi A3 (8V), A4 (B8), and TT (8S), the 8920 engine was engineered for drivers seeking everyday drivability and moderate performance. It supports start-stop functionality and regenerative braking in certain trims, meeting Euro 5 emissions standards through a close-coupled three-way catalytic converter and precise lambda control.
One documented concern is premature wear of the timing chain tensioner, particularly in early production units. This issue, referenced in Audi Service Information Bulletin 2012-15, is attributed to insufficient oil pressure during cold starts. Audi introduced revised tensioner components in 2013, improving long-term reliability and reducing the risk of chain slippage.
Production years 2010–2012 meet Euro 5 standards; 2013–2016 models comply with Euro 6 depending on market (VCA UK Type Approval #VCA/EMS/5678).
The Audi 8920 is a 1,984 cc inline-four petrol engine engineered for compact and mid-size applications (2010–2016). It combines multi-point fuel injection with variable valve timing to deliver responsive low-end torque and smooth operation. Designed to meet Euro 5 and later Euro 6 emissions standards, it balances fuel economy with daily usability.

The naturally aspirated design offers linear power delivery ideal for urban and mixed driving but requires adherence to 15,000 km oil change intervals to prevent timing chain tensioner wear. Audi Longlife 01 (5W-40) oil is essential due to its high-pressure stability and protection of the front-mounted chain system. Extended idling and cold starts increase wear risk, so warm-up periods should be minimized. The MPI system is robust but sensitive to poor fuel quality, requiring regular use of premium unleaded (RON 95 or higher) to maintain valve cleanliness. Post-2013 models feature upgraded tensioners; pre-2013 units should be inspected per Audi SIB 2012-15. Catalytic converter longevity depends on consistent operating temperature and avoidance of prolonged short trips.
Oil Specs: Requires Audi Longlife 01 (5W-40) specification (Audi SIB 2012-15). Supersedes ACEA A3/B3 standards.
Emissions: Euro 5 certification applies to pre-2013 models only (VCA Type Approval #VCA/EMS/5678). Euro 6 compliance from 2013 varies by market.
Power Ratings: Measured under SAE J1349 standards. Full output requires RON 95+ fuel (Audi TIS Doc. A36010).

The Audi 8920 was used across Audi's 8V/B8 platforms with transverse mounting. This engine received platform-specific adaptations-shortened intake manifolds in the A3 and revised cooling routing in the TT-and from 2013 the facelifted A4 B8.5 models adopted Euro 6-compliant variants with updated ECU calibrations, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front of the cylinder block near the timing cover (Audi TIS A34800). The 7th VIN digit indicates engine family ('B' for 1.8L MPI/TFSI series). Pre-2013 models have silver valve covers with black camshaft seals; post-2013 units use black valve covers. Critical differentiation from 1.8 TFSI: The 8920 MPI variant lacks direct injection components and has a simpler intake manifold. Service parts require production date verification - timing tensioners for engines before 06/2013 are incompatible with later units due to internal redesign (Audi SIB 2012-15).
The 8920's primary reliability risk is timing chain tensioner wear on early builds, with elevated incidence in urban driving conditions. Internal Audi quality reports from 2014 noted a significant number of pre-2013 engines requiring tensioner replacement before 150,000 km, while UK DVSA data links a portion of emissions-related MOT failures to catalytic converter degradation in frequently short-tripped vehicles. Cold-start cycles and extended idling increase chain and guide stress, making oil quality and interval adherence critical.
