How do you replace the battery in a BMW 1 Series F20?

Model: BMW Serie 1 MK 2, F20, F21 - Years 2011-2019
Part: Battery

Changing the battery on your car is not complicated but it requires a bit of attention and manual dexterity. Open the trunk and lift the bottom panel because the battery is there. Disconnect the negative pole, the black one, and then the positive one, the red one. Unscrew the support that holds the battery in place and carefully remove it because it is heavy. Insert the new battery, reconnect the positive pole first and then the negative one, secure everything properly and make sure it is stable. At this point, you need to register it with the OBD to avoid problems with the energy management system. If you have a diagnostic tool, do it yourself, otherwise it is better to go to the mechanic.

How to Reset the Central Locking of the Volkswagen Golf 4?

If the central locking system of the Volkswagen Golf 4 is not working, it is likely necessary to reset the system: to do this, open the driver's door and detach the side panel of the dashboard next to the steering wheel. Under this panel, you will find the fuses, including the one for the central locking, which is indicated in the manual as number 14. To reset the system, remove this fuse from its housing, then reinsert it or replace it with a new one of the same amperage: this will reset the central locking system.
