Preparation: tools and materials

Before you start disassembling, prepare everything you need. The absence of even one tool can slow down the process or lead to breakage of fasteners. Here's the full list:

  • πŸ”§ Plastic mounting blades (2–3 pcs.) - for removing clips without scratches. It is not recommended to use metal screwdrivers!
  • πŸ”© 10 mm socket wrench or socket β€” to unscrew the bolt securing the door to the hinge (during complete disassembly).
  • ⚑ Screwdriver T20 and T25 - for speaker and handle screws.
  • 🧲 Magnet or tweezers - so as not to lose small parts (for example, retaining rings).
  • πŸ“Έ Smartphone - for photographing the location of wires and clips before removal.
  • 🧴 Silicone grease (optional) - for processing the window lifter guides after assembly.

If you are planning a replacement window regulator or castle, additionally you will need:

  • πŸ”„ New mechanism (for example, art. 5Q1837415 for electric drive or 5Q1837015 for manual).
