Variant HistoryMercedes-Benz A-Class A160 / A180 Petrol - Engine History & Specs at a Glance
The A160 and A180 petrol badges have spanned three generations of the Mercedes-Benz A-Class, evolving from naturally aspirated simplicity to turbocharged efficiency. The W169 (2004-2012) used Mercedes' own M266 engine family, while the W176 (2012-2018) introduced turbocharging with the M270, and the W177 (2018-present) continued with the co-developed M282 unit. Both badges represent entry-level and mid-range petrol options respectively.

Common Failure
The M266 is generally robust but suffers from oil sludge buildup due to extended service intervals, ignition coil failure causing misfires, and timing chain wear on higher-mileage units. The ECU (SIM266) is also a known failure point on 2009-2012 models.
The A160 and A180 petrol engines have evolved across three generations - from the naturally aspirated M266 (W169) to the turbocharged M270 (W176) and the co-developed M282 (W177). Each has distinct failure patterns. Rebuilt A160 and A180 petrol engines through EnginesMarket include upgraded components addressing the original failure points, plus a minimum 12-month unlimited-mileage warranty.
Why the W176 A160 / A180 Petrol Rattles on Cold Start
Affected Vehicles
Mercedes-Benz A-Class A160 and A180 petrol (M270.910, W176, 2012-2018)
Typical Failure Mileage
80,000-150,000 miles
Root Cause
The M270 turbo petrol engine's timing chain can stretch prematurely, causing a metallic rattling noise when starting from cold. The chain tensioner can also fail, allowing the chain to skip timing. Post-2014 models have strengthened timing components.

Vehicle Value Check
Vehicle Value Check
A typical W176 A160 or A180 petrol is worth £4,000-£12,000 depending on condition and mileage. For vehicles under £5,000, a preventative chain replacement (£1,200-£1,800) is usually the better financial decision than a full engine replacement. For higher-value examples, a rebuilt M270 with warranty (£1,800-£3,200) offers peace of mind. Post-2014 models have strengthened timing components, making failure less common.
Our Recommendation
Our Recommendation
If you hear a rattling noise from the engine on cold starts - especially between 80,000 and 120,000 miles - act immediately. A preventative chain replacement at a specialist saves thousands compared to waiting for failure. Once the chain jumps, piston-to-valve contact is almost certain and engine replacement becomes the only viable option.

Mercedes-Benz A-Class A160 / A180 Petrol Engine ReplacementFrequently Asked Questions
Question 1How much does a Mercedes-Benz A-Class A160 or A180 petrol engine replacement cost in the UK-
A replacement engine for an A160 or A180 petrol typically costs between £400 and £3,800 depending on the engine code and condition. Used M266 units start from £400-£900, reconditioned from £900-£1,600, and fully rebuilt M270 turbo engines from £1,800-£3,200. Labour for supply & fit adds £400-£800.
- Used M266 (W169 A160): £400-£900
- Rebuilt M270 (W176 A180): £1,800-£3,200
- Rebuilt M282 (W177 A180): £2,200-£3,800
Question 2Does the Mercedes-Benz A-Class A160 or A180 petrol have a timing belt or timing chain-
All A160 and A180 petrol engines use timing chains, not belts. The M266 (W169), M270 (W176) and M282 (W177) all 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 A160/A180 petrol engines: timing chain
- M270 chain stretch common at 80k-150k miles
- Regular oil changes are critical for chain longevity
Question 3What are the signs of timing chain failure in a Mercedes-Benz A-Class A180 petrol-
On M270-equipped A180 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
Question 4Is it worth replacing the engine in a Mercedes-Benz A-Class A160 or A180 petrol-
It depends on the generation and condition. A W169 A160 petrol is typically worth £1,500-£4,000 - a full engine replacement often exceeds the car's value, making a used engine or targeted repair (ignition coils, timing chain) more economical. A W176 A180 petrol is worth £4,000-£12,000 - a rebuilt M270 engine (£1,800-£3,200) can be a worthwhile investment if the car is in good condition. A W177 A180 petrol is worth £10,000-£20,000 - a rebuilt M282 engine is usually well within the car's value.
- W169 (2004-2012): used engine or targeted repair
- W176 (2012-2018): rebuilt M270 viable for good condition cars
- W177 (2018-present): rebuilt M282 usually justifies cost
Question 5What causes the Mercedes-Benz A-Class A160 petrol to misfire-
On the M266 engine (W169 A160, 2004-2012), misfires are most commonly caused by faulty ignition coils, worn spark plugs, or a compromised ECU. The engine may run unevenly, feel sluggish or rough, and the check engine light may illuminate. Replacing ignition coils and spark plugs at regular intervals is the most effective solution.
- Faulty ignition coils - most common cause
- ECU failure - known issue on 2009-2012 models
- Wiring harness issues - inspect for wear
Question 6What is the difference between the A160 and A180 petrol engines-
In the W176 generation (2012-2018), both the A160 and A180 use the same M270.910 1.6-litre turbo petrol engine, but with different ECU calibrations. The A160 produces 102 hp, while the A180 produces 122 hp. In the W169 generation (2004-2012), the A160 uses the 1.5-litre M266.920 (95 hp).
- W176: same M270 engine, different ECU tune
- A160: 102 hp, A180: 122 hp
- W169 A160: 1.5L M266, 95 hp
