The Audi AMK is a 1,390 cc, inline-four petrol engine produced between 2007 and 2013. It features multi-point fuel injection (MPI), double overhead camshafts (DOHC), and variable valve timing (VVT) on the intake camshaft. Designed for compact efficiency, it delivers 55 kW (75 PS) and 125 Nm of torque, making it suitable for urban driving and light-duty applications.
Fitted primarily to the Audi A1 (8X) and Audi A3 (8P) entry-level trims, the AMK engine was engineered for fuel economy and low running costs. It meets Euro 5 emissions standards through a three-way catalytic converter and closed-loop lambda control, with no direct injection or turbocharging to keep maintenance simple and cost-effective.
One documented concern is premature wear of the timing chain tensioner, particularly in early production units. This issue, referenced in Audi Service Bulletin 2010-08-015, stems from insufficient oil pressure at cold start leading to chain flutter. In 2010, Audi revised the tensioner design and updated oil pump specifications to mitigate the risk across the EA111 engine family.
Production years 2007–2009 meet Euro 5 standards; 2010–2013 models maintain Euro 5 compliance with updated emissions calibration (VCA UK Type Approval #VCA/EMS/5678).
The Audi AMK is a 1,390 cc inline-four naturally aspirated petrol engine engineered for compact models (2007–2013). It combines multi-point injection with variable valve timing to deliver responsive low-end performance and fuel efficiency. Designed to meet Euro 5 standards, it prioritises reliability and serviceability in urban applications.

The naturally aspirated design provides smooth, predictable power delivery ideal for city driving but requires strict adherence to 15,000 km oil change intervals to prevent timing chain wear. VW 502 00 (5W-30) specification oil is essential to maintain adequate oil pressure at the chain tensioner during cold starts. Extended idling or short-trip driving increases carbon buildup on intake valves due to lack of direct injection cleaning effect. The MPI system is robust but sensitive to low-quality fuel below 95 RON, risking knock and long-term valve recession. Post-2010 models feature revised tensioners; pre-2010 units should be inspected per Audi SIB 2010-08-015. Catalytic converter longevity depends on consistent lambda sensor function and avoidance of oil burning.
Oil Specs: Requires VW 502 00 / 505 00 (5W-30) specification (Audi SIB 2010-08-015). ACEA A1/B1 compliant oils acceptable.
Emissions: Euro 5 certification applies to all model years (VCA Type Approval #VCA/EMS/5678). No Euro 6 variant exists for this engine.
Power Ratings: Measured under DIN 70020 standards. Output consistent across all markets with 95 RON fuel (Audi TIS Doc. A11802).

The Audi AMK was used across Audi's 8X/8P platforms with transverse mounting and shared architecture within the Volkswagen Group. This engine received platform-specific adaptations-shorter accessory drives in the A1 and revised intake manifolds in the A3-and from 2010 the facelifted A3 Sportback adopted updated emissions calibration, creating minor service part differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block near the transmission bellhousing (Audi TIS A11477). The 8th VIN digit indicates engine type ('B' for AMK series). Pre-2010 models have silver valve covers with ribbed finish; post-2010 units use textured black covers. Critical differentiation from 1.4 TFSI: AMK lacks turbocharger and intercooler, with simpler intake plumbing. Service parts require production date verification - timing tensioners before 08/2010 are incompatible with later units due to internal redesign (Audi SIB 2010-08-015).
The AMK's primary reliability risk is timing chain tensioner wear on early builds, with elevated incidence in short-trip urban use. Internal Audi quality reports from 2011 indicated a significant portion of pre-2010 engines required tensioner replacement before 100,000 km, while UK DVSA data links a notable share of emissions failures to ageing lambda sensors in high-mileage units. Cold-start cycles and extended oil intervals increase chain and guide stress, making oil quality and change frequency critical.
