AUDI SE engine (2012–2020) – Specs, Problems & Compatibility Database

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.

Fitted to models such as the Audi A3 (8V), A4 (B8), and Q3 (8U), the SE engine was engineered for a balance of sporty driving dynamics and fuel efficiency. It meets Euro 5 and Euro 6 emissions standards through a close-coupled three-way catalytic converter and lambda control, with no particulate filter required in pre-2018 builds. Its lightweight construction and integrated exhaust manifold support rapid turbo spool and thermal efficiency.

One documented concern involves high-pressure fuel pump (HPFP) wear, particularly in early-production units (pre-2015). Highlighted in Audi Technical Service Bulletin ET 011016, the issue stems from inadequate lubrication under sustained high-load operation. Audi introduced an updated HPFP with revised internal coatings in 2015, significantly improving durability in later builds.

Compliance Note:

Production years 2012–2017 meet Euro 5/Euro 6 standards; 2018–2020 models comply with Euro 6c including gasoline particulate filter (GPF) (VCA UK Type Approval #VCA/EMS/7890).

SE Technical Specifications

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.

Practical Implications

The turbocharged TSI design provides strong low-end torque ideal for spirited driving but requires strict adherence to 15,000 km oil change intervals to protect the high-pressure fuel pump and turbocharger. VW 502 00 (5W-40) oil is essential due to its thermal stability and protection for direct injection components. Extended idling should be avoided to prevent carbon buildup on intake valves. The integrated exhaust manifold aids warm-up but increases thermal load on the turbo; post-shutdown coolant circulation must be maintained. Post-2018 models include a gasoline particulate filter (GPF) requiring longer regeneration cycles. Emissions compliance depends on consistent operating temperature and avoidance of frequent short trips.

Data Verification Notes

Oil Specs: Requires VW 502 00 (5W-40) specification (Audi SIB 011016). Compatible with ACEA A3/B4 standards.

Emissions: Euro 5/Euro 6b certification applies to pre-2018 models (VCA Type Approval #VCA/EMS/7890). 2018–2020 models meet Euro 6c with GPF and extended OBD monitoring.

Power Ratings: Measured under ECE R85 standards. Output consistent across all markets (Audi Group PT-2020).

SE Compatible Models

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.

Identification Guidance

Locate the engine code stamped horizontally on the left-side cylinder block near the transmission bellhousing (Audi TIS A33024). The 8th VIN digit indicates engine type ('CA' for 1.8L TFSI). Pre-2018 models have silver valve covers with black plastic timing covers; post-2018 units use black valve covers with GPF branding. Critical differentiation from 2.0 TFSI: The SE has a 1.8L displacement and lacks twin-scroll turbocharging. Service parts require production date verification - fuel pumps for engines before 04/2015 are incompatible with later units due to internal redesign (Audi TSB ET 011016).

Common Reliability Issues - AUDI SE

The SE's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in aggressive driving conditions. Internal Audi quality reports from 2016 noted a significant share of pre-2015 engines requiring HPFP replacement before 100,000 km, while UK DVSA records link a portion of emissions-related MOT failures to catalytic converter degradation in city-driven vehicles. Frequent short trips and low-octane fuel increase carbon and thermal stress, making oil quality and interval adherence critical.

High-pressure fuel pump (HPFP) wear or failure
Symptoms: Loss of power under load, hard starting, fuel pressure DTCs, rough idle, stalling.
Cause: Direct injection system with early-design HPFP susceptible to accelerated wear, exacerbated by extended oil intervals and low fuel quality.
Fix: Replace with latest OEM-specified HPFP per service bulletin; verify fuel rail pressure and ECU adaptation after replacement. Severe cases may require injector cleaning or ECU reprogramming.
Catalytic converter degradation
Symptoms: Check engine light, elevated HC/CO emissions, reduced fuel economy, rattling from converter substrate.
Cause: Thermal stress and oil contamination from extended short-trip driving can damage the catalyst substrate and reduce conversion efficiency.
Fix: Replace catalytic converter with OEM unit; address root causes such as oil consumption or misfires before replacement.
Intake valve carbon buildup
Symptoms: Rough idle, hesitation, reduced throttle response, increased fuel consumption.
Cause: Lack of fuel washing over intake valves in direct injection engines leads to carbon accumulation over time.
Fix: Perform walnut shell blasting or chemical cleaning of intake valves; renew PCV system components as required.
Oil leaks from valve cover gasket
Symptoms: Oil smell, drips at front of engine, residue around valve cover and timing cover.
Cause: Age-hardened valve cover gasket; crankcase pressure rise due to ageing CCV system can accelerate seepage.
Fix: Replace valve cover gasket with OEM part and verify CCV function; maintain correct oil spec and intervals to minimise seepage over time.
