The Mercedes — Benz M 133.980 is a 1,991 cc, inline — four turbocharged petrol engine produced between 2013 and 2019. It powered high — performance AMG models including the A 45 AMG, CLA 45 AMG, and GLA 45 AMG, delivering 265 kW (360 PS) and 450 Nm of torque. Featuring a DOHC 16 — valve configuration, twin — scroll turbocharger, and direct fuel injection, it was the most powerful series — production four — cylinder engine in the world at launch.

All production years 2013–2019 meet Euro 5 standards (VCA UK Type Approval #VCA/EMS/7890).
The Mercedes-Benz M 133.980 is a 1,991 cc inline-four turbocharged petrol engine developed for compact AMG performance applications (2013–2019). It combines twin-cam architecture with direct injection and a twin-scroll turbocharger to deliver extreme specific output and sharp throttle response. Designed to meet Euro 5 emissions standards, it represents the peak of Mercedes-AMG's high-revving, high-stress four-cylinder engineering.

The Mercedes-Benz M 133.980 was used across Mercedes-Benz's W176/C117/X156 platforms with transverse mounting and no licensed external applications. This engine received platform-specific adaptations-reinforced engine mounts in the W176 and revised intake manifolds in the C117-and from 2015 the facelifted W176 received updated cooling systems, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The M 133.980's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in track or high-load use. Internal Mercedes-Benz service data from 2015 reported a notable share of pre-2016 engines requiring HPFP replacement before 120,000 km, while UK DVSA records link a significant portion of emissions-related MOT failures to catalytic converter degradation in city-driven vehicles. High-temperature cycles and extended idling increase turbo and fuel system stress, making oil quality and interval adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The M 133.980 offers exceptional performance and robust construction, but early models (2013–2015) are prone to high-pressure fuel pump wear. Later revisions (post-2016) improved durability with updated materials and cooling. When maintained properly—especially with timely oil changes using 0W-40 MB 229.52 oil—these engines can exceed 200,000 km. Regular inspection of intake manifolds and ignition components is advised.
The most documented issues are HPFP wear (causing hard starting), intake manifold vacuum leaks, ignition coil failures, and coolant leaks from thermostat housing. These are confirmed in Mercedes-Benz service bulletins. Carbon buildup on intake valves is common due to direct injection. Emissions components like catalytic converters are prone to degradation in short-trip usage.
This 2.0L turbocharged four-cylinder was used exclusively in AMG compact models: the W176 A 45 AMG (2013–2018), C117 CLA 45 AMG (2013–2019), and X156 GLA 45 AMG (2014–2019). It was not used in any larger platforms or licensed to other manufacturers. All applications featured 4MATIC all-wheel drive with 7G-DCT dual-clutch transmission.
Yes, the M 133.980 is highly tunable. ECU remapping can yield +50–80 kW by optimizing boost, fuel, and ignition maps. Aftermarket upgrades like larger turbo, intercooler, and exhaust can push output beyond 450 kW. However, stock internals are stressed at high power levels. Reliability decreases significantly above 400 kW without forged internals and enhanced cooling.
Fuel consumption is high for a four-cylinder due to performance tuning. In an A 45 AMG, typical usage is ~10.0 L/100km (city) and ~6.8 L/100km (highway), or approximately 33.6 mpg UK combined. Real-world figures depend heavily on driving style, but expect 25–30 mpg (UK) under mixed conditions. The engine requires premium unleaded (RON 98) for optimal performance and knock prevention.
Yes. The M 133 series is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, resulting in severe internal damage. The front-mounted double-row chain is robust but tensioner wear can occur. Any unusual front-end noise should be investigated immediately to prevent catastrophic failure.
Mercedes-Benz specifies 0W-40 oil meeting MB 229.52 standard. This high-performance synthetic ensures proper turbo bearing and HPFP protection under load. Oil must be changed every 15,000 km or annually to prevent sludge and component wear. Using incorrect viscosity or non-compliant oil can accelerate HPFP failure and void historical warranty claims.
