Mercedes M282 1.3 L Turbo Engine (2018–Present)
The Mercedes M282 engine is a compact, turbocharged inline-4 introduced in 2018 and co-developed with Renault-Nissan. It powers models such as the A-Class (W177), CLA (W118), GLA (H247), and GLB (X247).
Despite its small displacement, the M282 offers responsive performance (134–161 hp) and impressive efficiency, thanks to features like direct injection, a twin-scroll turbo, cylinder deactivation, and gasoline particulate filter (GPF).
While generally reliable, some owners have reported carbon buildup, thermostat faults, and AC-related leaks, making proper maintenance crucial.

M282 Engine Oil Capacity
- – Capacity: ~5.4 liters (with filter)
- – Oil type: MB 229.5 fully synthetic, e.g. 5W-30 or 0W-40
- – Change interval: 10k mi / 12 months (more frequent recommended for heavy driving)
M282 Thermostat : Function & Issues
The thermostat regulates engine operating temperature.
- – Failure signs: Overheating, fluctuating temps, slow cabin heating
- – Fix: Replace with OEM thermostat quickly to prevent head gasket damage
- – Tip: Always inspect coolant hoses during thermostat replacement
M282 Engine Tuning Potential
Although compact, the M282 offers tuning opportunities thanks to its turbo setup.
- – ECU remap: +20–30% power gains possible (warranty risk).
- – Hardware upgrades: Intercooler, intake, exhaust for improved airflow.
- – Caution: Increased boost = more stress on engine components.
