Step-by-step instructions: remove the trim without damage
The dismantling process takes from 30 to 60 minutes depending on experience. The main rule is act consistently and do not use excessive force. Let's start with preparation:
- Remove the decorative handle trim (it is attached with latches). Pry it with a spatula from the inside (interior side) and pull it towards you.
- Unscrew the screws under the trim (usually 2 pieces) and at the bottom of the trim (near the pocket).
- Remove the door lock plug (if there is one) - it is held on by a clip.
- Disconnect the wiring connectors from the power window buttons and speakers (be careful, do not pull the wires!).
Now let's move on to the casing itself. Start with bottom corner (from the loop side) and gradually snap off the clips with a spatula. Important: clips on Octavia Tour fragile, so move in a circle, evenly releasing the fasteners. If the casing does not give way, check that all screws are unscrewed.

Pay special attention mechanical door opening cable (if it is included in your configuration). It cannot be disconnected - just carefully remove it from the groove in the casing. On models with electric lock the cable may be missing.
โ ๏ธ Attention: On Octavia Tour A7 hidden in the casing tire pressure sensor (if the system is installed TPMS). When dismantling, do not pull on the wires - you risk tearing off the connector!
Common mistakes and how to avoid them
Even experienced car owners sometimes make mistakes when removing trim. Here are the most common ones and how to prevent them:
| Error | Consequences | How to avoid |
|---|---|---|
| Using metal tools | Scratches on plastic, broken clips | Use only plastic spatulas |
| Strong pressure on the casing when snapping | Cracks in plastic, deformation | Move in a circle, releasing the clips evenly |
| Forgot to disconnect the wiring connectors | Broken wires, short circuit | Check all connectors before final removal |
| Lost clips or screws | Unstable fixation of the casing after assembly | Place fasteners in a container with partitions |
Another common problem is speaker diaphragm damage in case of careless dismantling. If you are planning to replace the speakers, first disconnect the speaker connector and then remove the screws. On Octavia Tour front speakers are mounted on 4 T20 screws, rear - on 3 T25 screws.
If the clip breaks during removal, do not attempt to reuse it. Buy a new one (item number for Octavia A5: 6Q0 868 251) - it costs a penny, but will preserve the integrity of the skin.

1Z6 837 701/702). - ๐ง Seals and drainage holes - if water accumulates in the door, clean the holes in the lower part (use
wire 1.5โ2 mm). - ๐ Wiring โ check the integrity of the insulation, especially in kinks (near the hinges).
If you removed the trim because creaks, please note:
- Plastic glass guides - they need to be lubricated
silicone grease(do not use WD-40!). - Sheathing fastenings - sometimes squeaking occurs due to loose clips.

5E0 837 715/716).
โ ๏ธ Attention: When replacing window regulator on Octavia Tour necessarily reset errors in the comfort control unit (BCM) through a diagnostic scanner. Otherwise, the glass may not synchronize with the buttons.
Sheathing assembly: how to prevent new problems

1.5โ2 Nm(do not overtighten!). - Check the operation of all mechanisms until the final fixation of the trim: window lifters, lock, buttons.
After assembly, turn on the ignition and test:
- The operation of the window lifters (they should move smoothly, without jerking).
- The sound of the speakers (is there any wheezing or distortion).
- Door lock (opens/closes the first time).
If new creaks appear after assembly, most likely you did not secure the trim tightly enough or forgot to install sealing gaskets between the plastic and metal of the door.
