The F20 1 Series is one of the few compact hatchbacks with rear-wheel drive. Built from 2011 to 2019 as a five-door (F20) and three-door (F21), it combines BMW driving dynamics with compact dimensions and economical engines.
It is a popular first BMW and an affordable used car, but engine choice and history matter. In this buying guide we explain the engines, the 2015 update, common issues and what to check before buying an F20 1 Series.
Why the F20 1 Series is special
Most compact hatchbacks use front-wheel drive. The F20 1 Series uses rear-wheel drive, with a longitudinal engine, like larger BMWs. This gives it balanced handling and a sporty feel.
The trade-off is slightly less interior space than some rivals. Its successor, the F40, moved to a front-wheel drive based platform. Our article on the BMW M135i explains the later car, and our M140i buying guide covers the fastest F20.
For enthusiasts, the F20 is a rare chance to own a compact car with the balance and steering feel of a larger BMW. Even the less powerful versions feel agile and enjoyable on twisty roads. The interior is well built, with a driver-focused dashboard and iDrive on many cars.
Petrol engines
The F20 used several petrol engines:
- Early four-cylinder turbo engines in the 114i, 116i and 118i, which need careful checks, including the timing chain and service history.
- Three-cylinder and four-cylinder modular engines after the 2015 update, such as the B38 and B48, which are generally considered more reliable. Our article on the BMW B48 engine explains the four-cylinder.
- Six-cylinder engines in the M135i and M140i.
Our article on BMW timing chain problems explains why some earlier engines need attention.
Diesel engines
Diesel versions include the 116d, 118d, 120d and 125d:
- N47: used in earlier cars. Some N47 engines were known for timing chain problems.
- B47: used after the update, generally considered more reliable. Our article on the BMW B47 diesel explains it.
Diesel models suit drivers who cover long distances. For short trips, the DPF can become a problem. Our article on the BMW DPF explains why.
The 2015 update
Around 2015, the F20 received an update with:
- Revised front and rear styling, including new lights.
- New modular engines with improved reliability and efficiency.
- Updated interior details and equipment.
Many buyers prefer updated cars, especially for the newer engines. Check the production date and engine code in the documents.
The update also improved the infotainment on many cars, with newer navigation systems and connectivity. Our article on BMW iDrive generations explains the systems used during this period.
Common issues
Points to check include:
- Timing chain noise on earlier petrol and N47 diesel engines.
- Oil leaks from gaskets.
- Coolant leaks and cooling system parts. Our article on BMW cooling system problems explains them.
- Run-flat tyres on many cars, which make the ride firm. Our article on BMW run-flat tyres explains them.
- Front suspension bushings and drop links.
- Clutch and dual-mass flywheel on manual cars. Our article on the BMW dual-mass flywheel explains the symptoms.
Gearboxes
The F20 was offered with six-speed manual gearboxes and an eight-speed automatic. The automatic is smooth and efficient, and very popular. Check for smooth shifts and ask about fluid changes. Our article on BMW transmission fluid explains why fluid matters.
The manual gearbox is enjoyable and suits the car's sporty character, but the automatic makes town driving easier and often helps resale value.
Test drive checklist
On the test drive:
- Start the engine cold and listen for rattles from the timing chain.
- Check for smoke and warning messages.
- Test the gearbox and clutch.
- Feel for vibration and listen for suspension knocks.
- Read the fault memory.
- Check the service history for regular oil changes.
Our complete checklist for buying a used BMW covers other checks.
Is the F20 1 Series a good buy?
The F20 1 Series is a fun, compact and affordable BMW. A post-update car with a B38, B48 or B47 engine and full service history is usually the safest choice. Enthusiasts looking for more performance should consider the M135i or M140i.
Our guide to the best first BMW M car explains other routes into fast BMWs, and our article on BMW diesel or petrol helps you choose the right engine.
Because many F20s were bought as affordable new cars and later used by young drivers, condition varies widely. Take your time, compare several cars and choose the one with the best history rather than the lowest price.
