In this article - step-by-step withdrawal algorithm taking into account the specifics Octavia A7 (including 2017 redesign), a list of necessary tools and Unique tips for working with plastic clipsThey often break down when they are untidy. We will also discuss how to avoid errors when turning off the wiring of lights and parking sensors, so as not to provoke errors in the onboard computer.
Preparation for dismantling: tools and conditions
Before starting work, make sure you have everything you need. Minimum set of tools bumper-off Octavia A7:
- ๐ง 10 mm socket wrench (for wheel arch bolts)
- ๐ง Screwdriver with Phillips bit T25 (for self-tapping under license plate)

- ๐ง Flashlight or head light (lower bumper lighting)
Important: if you plan bumper-to-bumper (for example, for painting), prepare in advance. masking tape And a marker to mark the location of clips and wires. This will save time when reassembling. Work in well ventilated area Dust and dirt from under the bumper can rise into the air.

| Knot | Connector location | Fixation type |
|---|---|---|
| Tail light | Inside the bumper, next to the wing mount | Plastic latch (push from top) |
