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 f…
Production years 2010–2012 meet Euro 5 standards; 2013–2016 models comply with Euro 6 depending on market .
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 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.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The Audi 8920 offers solid performance and efficiency, but early models (2010–2012) are prone to timing chain tensioner wear. Later revisions (post-2013) improved durability with updated components. When maintained properly—especially with timely oil changes using Audi Longlife 01 (5W-40)—these engines can reliably exceed 150,000 km.
Key issues include timing chain tensioner wear (especially on cold starts), intake carbon buildup affecting idle quality, catalytic converter failure due to short trips, and oil leaks from the valve cover gasket. These are documented in Audi service bulletins and supported by field failure data.
The 8920 engine was used in the Audi A3 (8V, 2013–2016), A4 (B8/B8.5, 2010–2015), and TT (8S, 2015–2016). It was primarily offered as the 1.8 TFSI 140 PS variant, with Euro 5 and later Euro 6 emissions compliance depending on model year and market.
Aftermarket ECU tuning is common on the 8920 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In combined driving, the 8920 achieves approximately 6.5–7.2 L/100 km (44–39 mpg UK). Highway efficiency improves to ~5.8 L/100 km (~49 mpg UK), while city driving may reach 8.0 L/100 km (~35 mpg UK). Real-world economy depends on driving style and condition.
Yes. The 8920 is an interference engine, meaning that if the timing chain fails, the pistons can strike the open valves, resulting in severe internal damage. This makes timely inspection and replacement of the timing system critical, especially on high-mileage or poorly maintained units.
Audi specifies SAE 5W-40 oil meeting Audi Longlife 01 standard. Use only high-quality synthetic oil designed for petrol engines and change it every 15,000 km or annually to ensure proper lubrication of the timing chain and reduce carbon buildup.
