How to Restore the Headlamps of the Opel Astra H with Liquid Polycarbonate

Model: Vauxhall Astra Astra H - Years 2004-2010
Part: Headlight

In this video, see how to restore the headlamps of the Opel Astra H: this system crystallises the opaque polycarbonate, returning it to transparency. The process occurs through the evaporation of a chemical substance like acetone, which is one of the components of polycarbonate. The vapour emitted from the acetone initiates a process that crystallises the material, and it is not limited to simple polishing, making it much more durable. You can find this product on Amazon with code B09L1M1JL9, priced at £16.01, with free delivery for Prime customers. The usage is very simple; after thoroughly cleaning the optical unit, spray the product slowly as shown in the video; you will visibly see the headlamp restoration in a wonderful way!

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.
