The B4820 two-litre four-cylinder engine in BMW's current F20-generation 120i uses a timing chain.
The fuse box in this car is fiendishly located behind the glove box. To access it, you first need to unclip the strut that controls the glove box lid’s action, unclip the two sides of the glove box where it pivots (there’s a plastic tab on each side) pull the glove box inner down and then you should be able to see the fuses laid out deep inside the dashboard. Next to the access panel, there should be a folded chart showing which fuse does what. There are some excellent online tutorials on how to do this.
If this chart is missing (and it’s possible as it’s a loose-leaf sheet of paper) there are lots of online guides to show you what fuse protects what circuit.
To remove or replace the fuses themselves, I’d recommend a specific set of long-nosed pliers designed for this job as there’s very poor access to the actual fuses and getting at them by hand is going to be a pain.
The current F20-series BMW 120i is rated on a combined cycle as using 5.9-litres of unleaded fuel per-100km. While it isn't as good as other small hatchbacks in the class it would still be considered good fuel consumption, especially given most large family cars would consume 10-12-litres per-100km.
