BMW 1 Series F20
2011-2019
The BMW F20 is the second generation of the BMW 1 Series, predominantly available as a compact hatchback. Introduced in 2011 and produced until 2019, it's known for its unique combination of premium features, compact dimensions, and engaging driving dynamics typical of BMW's rear-wheel-drive architecture (before the switch to front-wheel drive in its successor). Here's a short review of the BMW F20:**Performance and Handling:**
- The F20 is celebrated for its sporty handling and driving engagement, a standout in the compact hatchback segment. It offers a range of engine choices, from efficient three-cylinder engines to powerful four- and six-cylinder options in the M140i. The rear-wheel-drive setup (unique in its class) and well-tuned suspension contribute to the car's dynamic driving experience.
**Interior and Features:**
- The interior of the F20, while compact, is well-crafted with quality materials and a driver-focused layout. It offers a range of technology and comfort features, though the space in the rear and cargo capacity is somewhat limited due to the car's compact dimensions. The iDrive system provides control over entertainment, navigation, and vehicle settings.
**Design:**
- The F20 features a modern and sporty exterior design. Early models had a somewhat polarizing front-end design, which was refined with the facelift (LCI) in 2015. The car's compact proportions, combined with BMW's design language, give it a distinctive and dynamic appearance.
**Reliability and Maintenance:**
- The F20's reliability is generally in line with BMW standards. Diesel engines are known for their robustness and efficiency, while petrol engines offer a good balance of performance and reliability. Common issues include electronic components and, in some models, timing chain problems (mostly in early versions of the N47 diesel engine). Regular maintenance and attention to any unusual signs can ensure the car's longevity.
**Fuel Efficiency:**
- With a range of engine options, the F20 can be quite fuel-efficient, especially in models equipped with the three- or four-cylinder engines. The M140i, with its six-cylinder engine, offers exhilarating performance at the expense of higher fuel consumption.
In summary, the BMW F20 is a compelling choice for those looking for a premium, compact hatchback with excellent driving dynamics and a high-quality interior. It stands out in its segment for its rear-wheel-drive configuration and range of powerful engines. Prospective buyers should consider the usual BMW ownership costs and ensure a full service history to enjoy what the F20 has to offer fully.
Reliability
### Common Issues:
1. **Timing Chain (in certain engines):**
- Early versions of the N47 diesel engine and some petrol engines have been known to experience timing chain issues, which can lead to significant engine damage if not addressed. BMW made improvements in later models.
2. **Electrical Components:**
- Issues with electrical components, including sensors, connectors, and the battery management system, can occur. Regular diagnostics and prompt attention to warning lights can help address these issues early.
3. **Cooling System:**
- The thermostat and water pump may fail, especially as the vehicle ages. Regular checks and maintenance can help prevent overheating and more severe engine issues.
4. **Steering Rack:**
- Some F20 models may experience issues with the electric power steering rack, which can be costly to replace.
5. **Fuel System (in diesel models):**
- Diesel models, particularly those with the N47 engine, may experience issues with the EGR valve and other fuel system components, which can affect performance and emissions.
### Maintenance Tips:
1. **Regular Inspections:**
- Routine inspections by a mechanic familiar with BMWs can help catch potential issues before they turn into major problems.
2. **Timely Oil Changes:**
- Using the correct oil and adhering to a regular oil change schedule is crucial to maintain engine health.
3. **Attention to Warning Lights and Messages:**
- Addressing warning lights and messages promptly can prevent minor issues from becoming major problems.
4. **Battery Management:**
- The F20 uses an intelligent battery management system. When replacing the battery, it's essential to register it with the vehicle's computer system to avoid charging issues and prolong the battery's life.
5. **Service History:**
- Ensure that the vehicle has a comprehensive service history, and consider a pre-purchase inspection for used vehicles to check for any underlying issues.
In conclusion, the BMW F20 can be a reliable vehicle if properly maintained and cared for. However, potential owners should be prepared for the possibility of higher maintenance costs compared to less complex vehicles. It's advisable to have a thorough pre-purchase inspection by a qualified mechanic and to review the vehicle's maintenance history to ensure that it has been well-maintained.
