Mercedes-Benz A-Class 200 Petrol Engine Replacement Compare Prices & Get Quotes

A replacement engine for an A200 petrol typically costs between £600 and £3,800 depending on the engine code and condition. Used M270 units start from £600-£1,500, reconditioned from £1,500-£2,800, and fully rebuilt M282 engines from £2,200-£3,800. Labour for supply & fit adds £400-£800.

• Used M270 (W176 A200): £600-£1,500
• Rebuilt M270 (W176 A200): £1,600-£3,200
• Rebuilt M282 (W177 A200): £2,200-£3,800

All A200 petrol engines use timing chains, not belts. The M270 (W176) and M282 (W177) both have timing chains designed to last the life of the engine with proper maintenance. However, the M270 is known for timing chain stretch on higher-mileage units - a metallic rattling noise on cold start is the classic warning sign.

• All A200 petrol engines: timing chain
• M270 chain stretch common at 80k-150k miles
• Regular oil changes are critical for chain longevity

On M270-equipped A200 petrol models (W176, 2012-2018), the most common symptom is a metallic rattling noise from the engine on cold start. Other signs include loss of power, rough idle, hesitation, and the engine management light illuminating. If you hear any unusual sounds, have the timing system inspected immediately - ignoring the rattle can lead to catastrophic engine failure.

• Cold-start rattle from the timing cover area
• Loss of power and rough running
• Engine management light activation

It depends on the generation and condition. A W176 A200 petrol is typically worth £4,000-£14,000 - a rebuilt M270 engine (£1,600-£3,200) can be a worthwhile investment if the car is in good condition. A W177 A200 petrol is worth £10,000-£22,000 - a rebuilt M282 engine (£2,200-£3,800) is usually well within the car's value. Always compare the cost of repair against the car's market value.

• W176 (2012-2018): rebuilt M270 viable for good condition cars
• W177 (2018-present): rebuilt M282 usually justifies cost
• Vehicle worth over £6,000: replacement usually justifies the cost

The M270 is Mercedes' own 1.6-litre turbo petrol engine used in the W176 A200 (2012-2018), producing 156 hp with a timing chain. The M282 is a 1.3-litre turbo petrol engine co-developed with the Renault-Nissan Alliance, used in the W177 A200 (2018-present), producing 163 hp. The M282 features Nanoslide cylinder coating technology and, in later models, 48V mild-hybrid assistance.

• M270: 1.6L, 156 hp, Mercedes-designed, W176 (2012-2018)
• M282: 1.3L, 163 hp, co-developed with Renault, W177 (2018-present), +7 hp, available with 48V mild-hybrid

Power loss in the A200 petrol can be caused by several issues depending on the engine. On M270 engines, timing chain stretch can cause cam timing drift, reducing power. On both M270 and M282, carbon buildup on intake valves from direct injection can restrict airflow. On M282 engines, water pump or thermostat failure can cause overheating and subsequent power reduction.

• Timing chain stretch (M270) - power loss + rattling
• Carbon buildup on intake valves - common on all direct injection engines
• Water pump/thermostat failure (M282) - overheating and power loss
