The Audi SE is a 1,798 cc, inline — four turbocharged petrol engine produced between 2012 and 2020. Part of the Volkswagen Group's EA888 Gen 3 engine family, it features double overhead camshafts (DOHC), direct fuel injection (TSI), and variable valve timing on both intake and exhaust camshafts. In standard tune, it delivers 132 kW (180 PS) at 3,800–6,000 rpm and 250 Nm of torque from 1,250 rpm, designed for responsive mid — range performance in compact and mid — size vehicles…
Production years 2012–2017 meet Euro 5/Euro 6 standards; 2018–2020 models comply with Euro 6c including gasoline particulate filter (GPF) .
The Audi SE is a 1,798 cc inline-four turbocharged petrol engine engineered for performance-oriented platforms (2012–2020). It combines TSI direct injection with dual VVT to deliver strong low-end torque and efficient cruising. Designed to meet Euro 5 and Euro 6 standards, it balances sporty responsiveness with everyday drivability.

The Audi SE was used across Audi's 8V/B8 platforms with transverse mounting and shared with Seat, Volkswagen, and Skoda under Group commonality. This engine received platform-specific adaptations-shorter intake manifolds in the A3 and revised ECU mapping for quattro variants-and from 2018 the facelifted A4 B8.5 adopted the GPF-equipped version, 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 SE engine offers strong performance and good efficiency but early models (2012–2014) had reliability concerns, particularly high-pressure fuel pump wear. Later revisions (post-2015) improved pump durability, so well-maintained examples can achieve high mileage. Regular servicing and using correct oil (VW 502 00 5W-40) greatly aid longevity. Avoidance of short-trip driving also helps prevent GPF and catalytic converter issues in post-2018 models.
The most common issues are high-pressure fuel pump wear (especially in pre-2015 units), intake valve carbon buildup affecting idle quality, catalytic converter degradation due to thermal stress, and valve cover oil leaks. These are documented in Audi service bulletins and supported by field failure data. Regular maintenance significantly reduces risk.
The SE engine was used in the Audi A3 (8V) from 2013–2020, A4 (B8) from 2012–2015, and Q3 (8U) from 2012–2018, primarily in the 1.8 TFSI variant. It was also shared across Volkswagen Group models including the Volkswagen Golf 7, Seat Leon (5F), and Skoda Octavia (5E). In Audi applications, it served as a performance-oriented petrol option before being phased out in favour of downsized turbo units.
Aftermarket ECU tuning is common on the SE 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 the Audi A3 1.8 TFSI, combined fuel economy is approximately 6.7 L/100km (~42 mpg UK). City driving typically sees 8.5 L/100km (~33 mpg), while highway runs can achieve 5.8 L/100km (~49 mpg). Real-world consumption depends on driving style, but the engine is optimised for balanced efficiency and sporty performance.
Yes. The SE engine is an interference design. If the timing chain fails or jumps, pistons can contact open valves, resulting in bent valves or piston damage. Immediate attention to any timing rattle is essential to avoid costly internal repairs. The chain is front-mounted and generally durable, but proper oil maintenance is critical.
Audi specifies 5W-40 oil meeting VW 502 00 standard. Use of correct specification oil is critical for turbocharger and HPFP longevity. Oil changes should be performed every 15,000 km or annually, whichever comes first, to maintain engine health and prevent premature wear.
