About the Bmw 1 Series F20
AI-generatedThe BMW 1 Series F20, produced from 2011 to 2019, marked a significant departure from its E87 predecessor by switching from rear-wheel drive to front-wheel drive architecture (initially remaining RWD until 2015 facelift for most models, then introducing FWD with F40 in 2019 - correction: F20 remained RWD throughout). This second generation offered a more refined driving experience with improved interior quality, better fuel efficiency, and more boot space. The F20 introduced BMW's signature kidney grille design with a sportier, more aggressive stance while maintaining the compact hatchback format that made the 1 Series popular among premium buyers. Available in three-door and five-door configurations, the F20 offered a wide range of engines from the economical 114i to the performance-oriented M135i and M140i variants, the latter producing up to 340bhp. The generation received a facelift in 2015 (LCI - Life Cycle Impulse) which brought updated LED headlights, revised front and rear bumpers, and improved infotainment systems. Throughout its production run, the F20 remained the only rear-wheel-drive premium hatchback in its class, offering enthusiasts a unique driving dynamic that competitors couldn't match.
Known Issues
Known Issues
F20 (2011-2019)
2011-2019
- Timing chain wear on N20 petrol engines (116i, 118i, 120i) causing rattling noise on cold starts, potentially requiring expensive replacement (£1,500-£3,000)
- Turbocharger failure on diesel models, particularly 118d and 120d, often around 80,000-100,000 miles
- EGR valve and DPF issues on diesel variants causing limp mode and poor running
- Electric power steering failures leading to heavy steering or warning lights
- Thermostat housing leaks on N20 and B48 engines causing coolant loss
- Runflat tyre wear causing vibrations and expensive replacement costs
- iDrive system freezing or rebooting randomly, particularly on pre-2015 models
- Front suspension bushes and drop links wearing prematurely, especially on M Sport models
- Oil leaks from rocker cover gaskets and oil filter housing on higher mileage examples
- Gearbox mechatronic issues on 8-speed automatic transmissions causing rough shifts

Best & Worst Years
Best & Worst Years
Best Years
- 2019 - Final production year with all updates, refined B48 engine replacing problematic N20, mature iDrive 6.0 system, and modern LED lighting throughout. Still under manufacturer warranty for late examples with improved build quality.
- 2018 - Benefits from 2015 LCI updates with none of the early N20 timing chain issues. M140i models from this year represent peak F20 performance with proven B58 engine and all modern features.
- 2016 - Introduction of the B58-powered M140i and updated B48/B47 engine family replacing earlier N-series units. Post-facelift benefits with improved reliability and updated technology at relatively accessible prices now.
Worst Years
- 2012 - Early production year suffering from highest incidence of N20 timing chain issues, immature iDrive system with various software glitches, and initial build quality niggles. Avoid early N20-powered 116i, 118i, and 120i models from this year.
- 2013 - Continues with problematic early N20 engines before BMW implemented partial fixes. Many examples now at high mileage where timing chain and turbocharger issues typically manifest, requiring expensive repairs.
Did You Know?
Did You Know?
The F20 M140i (2016-2019) was the last rear-wheel-drive hot hatch available with a six-cylinder engine, making it highly sought after by enthusiasts
BMW offered a 'Sport Line', 'Urban Line', 'M Sport', and 'Modern Line' trim system for the F20, allowing extensive personalisation beyond standard SE and Sport trims
The F20 was the first 1 Series to be built outside Germany, with production also taking place at BMW's facility in Regensburg and later in China for Asian markets
Pre-facelift F20 models (2011-2015) can be identified by their halogen or optional xenon headlights, while post-2015 LCI models feature standard LED units on most trims

Alternatives to Consider
Audi A3 8V (2012-2020)
More refined interior, quattro all-wheel drive option, and superior build quality, though less engaging to drive than the rear-wheel-drive F20
Mercedes-Benz A-Class W176 (2012-2018)
More luxurious cabin materials, competitive AMG variants (A45 with 381bhp), and slightly better reliability, but front-wheel-drive platform less dynamic
Volkswagen Golf Mk7 (2012-2019)
Lower running costs, more spacious interior, excellent build quality, and GTI/R models offer strong performance, though lacks premium badge appeal
Ford Focus ST Mk3 (2011-2018)
Significantly cheaper to buy and run, engaging driving dynamics, and strong performance from 250bhp turbo engine, but mainstream brand and interior quality
Owner Tips
- 1Always verify timing chain condition on N20 petrol engines (2011-2015 models) - listen for rattling on cold starts and request inspection camera evidence if buying
- 2Budget for runflat tyre replacements or consider switching to conventional tyres with spare wheel kit to improve ride comfort and reduce costs
- 3Ensure diesel models have been regularly driven on motorways to prevent DPF clogging - short urban journeys will cause expensive regeneration issues
- 4Join BMW ownership forums and consider an independent BMW specialist for servicing - can save 40-50% versus main dealer costs while maintaining quality
- 5Check for full BMW service history with evidence of oil changes every 10,000 miles maximum - longlife servicing can cause premature engine wear
- 6Inspect suspension bushes and drop links carefully, especially on M Sport models - these wear quickly and affect handling but are relatively inexpensive to replace
- 7For pre-2015 models, update iDrive software to latest version for improved stability and functionality - often done free at BMW dealers
