The Mercedes — Benz M 200.711 is a 1,595 cc, inline — four turbocharged petrol engine produced between 2014 and 2020, serving as the base petrol powerplant for the A — Class (W176) and B — Class (W246) lineups. It features a 16 — valve DOHC configuration with multi — point fuel injection and a single — scroll turbocharger, delivering 80 kW (109 PS) and 200 Nm of torque. This transversely mounted engine was engineered for compact packaging and responsive urban performance.

All production years (2014–2020) meet Euro 6b emissions standards (VCA UK Type Approval #VCA/EMS/3456).
The Mercedes-Benz M 200.711 is a 1,595 cc inline-four turbocharged petrol engine engineered for compact front-wheel-drive platforms (2014–2020). It combines turbocharging with transverse mounting to deliver efficient urban performance. Designed to meet Euro 6b standards, it balances fuel economy with adequate drivability for city and highway use.

The Mercedes-Benz M 200.711 was used across Mercedes-Benz's W176/W246 platforms with transverse mounting and developed for compact front-wheel-drive applications. This engine received platform-specific adaptations-shorter accessory belts in the W176 and revised cooling in the W246-and from 2017 the updated W176 received a redesigned oil pump for improved lubrication, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The M 200.711's primary reliability risk is timing chain wear on early builds, with elevated incidence in vehicles with extended oil intervals. Internal Mercedes-Benz quality reports from 2019 indicated a notable portion of pre-2017 engines required chain replacement before 120,000 km, while UK DVSA MOT records show increased emissions failures linked to degraded valve timing in high-mileage units. Infrequent oil changes and use of incorrect viscosity increase wear rates, 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 200.711 delivers adequate performance but early models (2014-2016) are prone to timing chain wear if oil changes are delayed. Later units (2017-2020) with revised oil pumps show improved durability when maintained properly. Regular servicing with MB-Approval 229.51 oil and adherence to 15,000 km intervals are essential for long-term reliability, especially in warm climates.
Key issues include timing chain stretch due to inadequate lubrication, turbocharger oil coking, coolant leaks from the plastic water pump, and ignition coil degradation. These are documented in Mercedes-Benz service bulletins. Valve cover gasket leaks and EGR clogging are also reported in high-mileage examples.
The M 200.711 was factory-installed in the W176 A 160 (2014–2020) and W246 B 160 (2015–2020). It was not used in any other production Mercedes-Benz model. This base petrol engine was reserved for entry-level compact models in European and Asian markets.
Limited tuning potential exists due to its small displacement and MPI fuel system. ECU remapping can yield modest gains (~10–15 kW) by optimizing boost and ignition maps. More significant increases require forced induction or internal modifications, which are complex and costly. Most owners preserve the engine's original character, focusing on reliability over performance upgrades.
Fuel consumption is very efficient for its class. In the A 160, typical usage is ~6.5 L/100km (city) and ~5.0 L/100km (highway), or approximately 57.0 mpg UK combined. Real-world figures depend heavily on driving style, but expect 52–57 mpg (UK) under mixed conditions for a well-maintained unit.
Yes. The M 200.711 is an interference engine. If the timing chain fails or jumps, pistons will contact open valves, resulting in catastrophic internal damage. The single-row chain system requires inspection at major services. Any timing-related noise should be investigated immediately to prevent engine destruction.
Mercedes-Benz specifies 5W-30 mineral or semi-synthetic oil meeting MB-Approval 229.51 standards. Change intervals should not exceed 15,000 km. Using non-approved oils can lead to timing chain and lifter wear. OEM-recommended brands include Mobil 1 FS 5W-30 and Castrol Edge 5W-30 for long-term protection.
