Removing the front fender ล koda Octavia A5 - a task that owners face when doing body repairs, replacing a headlight or bumper. The process requires care and knowledge of the design features of the model, since incorrect actions can lead to damage to plastic clips, wiring or adjacent panels. In this article we will analyze the step-by-step algorithm for removing the wing, list the necessary tools and point out critical moments, which are often overlooked even by experienced craftsmen.
Difference Octavia A5 (2004โ2013) from newer generations - in attaching the wing to the body. Both standard bolts and hidden pistons are used here, access to which is difficult without first dismantling other elements. If you are planning to work with your own hands, keep in mind: without preparation, the process can take 3-5 hours, and with an assistant - half as much. The main rule is do not use excessive force to plastic parts to avoid cracks.
Preparation for dismantling: tools and materials
Before starting work, make sure you have everything you need. The absence of even one tool can slow down the process or lead to improvisations that are dangerous for the body. Here's the full list:
- ๐ง Socket set and ratchet wrench (sizes: 10 mm, 13 mm, Torx T25/T30)
- ๐จ Plastic installation tool (for removing clips and latches)
- ๐ฉ Screwdriver with Phillips and flat bit
- ๐งฒ Magnetic holder (for ease of working with bolts in hard-to-reach places)
- ๐ฅ Construction hair dryer (optional, for softening sealant)
- ๐งด Silicone grease or WD-40 (for treating rusted fasteners)
- ๐ฆ Containers for sorting bolts and clips (so as not to mix them up during assembly)
Pay special attention plastic clips. B Octavia A5 they often break if removed carelessly, and original spare parts can be expensive. Purchase a set of spare clips in advance (item no. 1J0 853 671 for the front bumper and 1K0 853 663 for the wing). Also prepare your workspace: it is better to place the car on a level area with good lighting or in a garage with a pit.
โ ๏ธ Attention: If the fender is damaged as a result of an accident, check the integrity before dismantling front pillar and spar. Deformation of these elements may require additional body repairs, and in this case it is better to entrust the removal of the wing to professionals.

Step-by-step instructions: removing the front bumper
Removing the wing Octavia A5 always starts with removing the front bumper. This is necessary to access hidden fasteners and pistons. Follow the algorithm:
- Open the hood and disconnect the negative terminal of the battery (this will prevent a short circuit when working with the headlight wiring).
- Remove the plastic plugs under the bumper (usually there are 4โ6 of them). They are attached with latches - pry them off with a plastic spatula.
- Unscrew the bumper mounting bolts:
- ๐ฉ Two bolts under the hood (at the edges, next to the headlights) - size
10 mm. - ๐ฉ Four bolts from the bottom (two in the center and two on the sides) - size
13 mm. - ๐ฉ Two pistons in the wheel arches (accessible after removing the fender liners).
- ๐ฉ Two bolts under the hood (at the edges, next to the headlights) - size
If the bumper is โstuckโ to the body due to old sealant, use a hair dryer to soften the glue. Heat sections for 20-30 seconds, then try to remove the bumper with a plastic spatula. Never use metal tools for these purposes - they will leave scratches on the paintwork.
โ๏ธ Checklist before removing the bumper
Removing fender liners and accessing hidden fasteners
After removing the bumper, you need to remove the fender liners (plastic liners in the wheel arches). This will give access to the bolts holding the fender to the body. Algorithm of actions:
- Unscrew the screws along the perimeter of the fender liner (usually 6โ8 pieces, size
Torx T25). - Remove the clips at the bottom of the arch. They break often, so prepare a replacement in advance.
- Bend the fender liner and carefully pull it out of the arch. If it gets caught on the brake hose or spring, do not pull by force - find the place of fixation and release it.
Under the fender liner you will see:
- ๐ง Three bolts securing the fender to the body (two at the top and one at the bottom).
- ๐ Turn signal wiring connector (if the fender is removed from the right side).
- ๐ ๏ธ The piston for attaching the bumper to the fender (sometimes remains on the bumper after it is removed).
โ ๏ธ Attention: On models with xenon headlights The ignition unit runs under the fender liner. Before removing the wing, disconnect the connector from it and fix the unit to the side so as not to damage the wires.
If the fender bolts are rusty, treat them with WD-40 10-15 minutes before removing them. Do not use an impact tool as this may strip the threads in the body.
Detaching the wing from the body: bolts and welding points
Now we move on to the main stage - removing the wing itself. B Octavia A5 it is attached to the body at several points:
| Attachment point | Fastener type | Quantity | Tool |
|---|---|---|---|
| Top (to the rack) | Bolt M8 | 2 pcs. | Head 13 mm |
| Bottom part (towards the threshold) | Bolt M6 | 1 piece | Head 10 mm |
| Front (to bumper) | Piston | 1 piece | Plastic spatula |
| Welding points (inside the arch) | Spot welding | 3โ4 pcs. | Drill 6 mm |
Start by unscrewing visible bolts (upper and lower). Then go to welding points - they need to be drilled out. Use a 6mm drill bit, working at low drill speed. After drilling, carefully separate the wing from the body, prying it off with a mounting spatula. If the wing โdoes not give inโ, check that all the bolts are unscrewed - the bottom bolt at the threshold is often missed.
When dismantling the right side, do not forget to disconnect the connector turn signal and temperature sensor (if it is installed in the wing). There may be a headlight washer tube on the left side - it also needs to be freed from its mountings.
What to do if a bolt breaks in the body?
If a bolt breaks off when unscrewing, do not try to remove it with pliers - this will damage the thread. Instead:
1. Drill a hole in the center of the bolt with a 2-3 mm drill.
2. Insert the extractor (or a self-tapping screw with a left-hand thread) into the hole and unscrew the fragment.
3. Tap the threads with the appropriate size tap.
If the thread is damaged, use a repair kit (sleeve with an increased diameter).
Nuances when working with left and right wings
Although the process of removing the wings is Octavia A5 similar, there are differences depending on the side:
Right wing
- ๐ Availability of connector turn signal and temperature sensor (on some trim levels).
- ๐ The fuse box is located closer to the fender - be careful when working with the wiring.
- ๐ง Additional bolt for fastening to the bumper reinforcement (can be hidden under a plastic cover).
Left wing
- ๐ฆ Headlight washer tube (if xenon equipped) - requires careful disconnection.
- ๐ The battery is located nearby - the risk of a short circuit is higher if the terminal is not disconnected.
- ๐ ๏ธ More welding points due to attachment to the spar (may require an angle grinder to remove cleanly).
On the left wing there are often problems with washer tube. If it bursts, the entire hose will need to be replaced (part no. 1K0 955 655). To avoid this, before removing the fender, disconnect the tube from the washer pump (located under the hood on the left) and drain the fluid.
When working on the left wing, be sure to disconnect the battery! The risk of a short circuit when the tool comes into contact with the body ground and the positive terminal is extremely high.
Installing a new wing: sequence and tips
The wing is installed in the reverse order, but taking into account several critical points:
- Surface preparation:
- Clean the welding points from rust and old sealant.
- Apply anti-corrosion primer on exposed metal areas.
- Wing mount:
- Start with the top bolts, then secure the bottom ones.
- Use new pistons for attaching to the bumper.
- Restore welding points using
spot weldingor bolts and nuts (if welding is not available).
- Wiring connection:
- Check the integrity of the turn signal connectors and sensors.
- Make sure the washer tube (on the left fender) is not kinked.
- Adjusting the gaps:
- The gaps between the fender and the hood/bumper should be the same (optimally 3โ5 mm).
- If necessary, loosen the bolts and adjust the wing position.
After installing the wing, check the operation of all systems:
- ๐ฆ Turn on turn signals and low beam - make sure that the lamps are lit without flickering.
- ๐ฆ Test headlight washer (if applicable).
- ๐ Check whether the fender touches the wheel when turning the steering wheel.
โ ๏ธ Attention: If after installing the wing there is creaking when moving, most likely, one of the clips on the bumper or fender liner did not snap fully into place. Disassemble the problem area and reinstall the fasteners.
Common mistakes and how to avoid them
Even experienced craftsmen make mistakes when working with wings Octavia A5. Here are the most common ones and ways to prevent them:
- ๐ง Broken thread in the body - Occurs when using the wrong tool or excessive force. Always use ratchet sockets and avoid impact drivers.
- ๐ Damaged wiring โ often happens when connectors are disconnected carelessly. Before dismantling, take a photo of the location of the wires.
- ๐ ๏ธ Gap mismatch โ if the wing is installed crookedly, it is noticeable. Use shims for alignment.
- ๐ฅ Fire due to short circuit - don't forget to disconnect the battery! It is especially dangerous to work with the left wing due to its proximity to the positive terminal.
Another typical problem is corrosion at fastening points. After removing the old wing, be sure to treat the body rust converter (for example, ASTROhim Antiruster) and apply primer before installing a new element. This will extend the life of the body and prevent metal rotting.
If you are removing the fender for painting, do not forget to cover the adjacent panels (hood, bumper, door) with masking tape. This will protect them from paint and abrasive particles when sanding.
FAQ: Answers to frequently asked questions
Is it possible to remove the wing Octavia A5 without removing the bumper?
Technically it is possible, but it is extremely inconvenient. Without dismantling the bumper, you will not have access to the lower bolts and pistons, which can damage the wing during forceful removal. We still recommend removing the bumper - it will take an additional 30-40 minutes, but will save time and nerves in the future.
How much does it cost to replace a wing at a service center?
The cost of working in a car service depends on the region and complexity of the task:
- Removing/installing the wing - from 3,000 to 6,000 rubles.
- Replacement with painting (including materials) - from 15,000 to 25,000 rubles.
- Additional work (welding, anti-corrosion treatment) - from 2,000 rubles.
The price of a new wing (original) is approx. 20,000โ30,000 rubles, analogue (for example, Febi or Topran) will cost 8,000โ15,000 rubles.
What sealant should I use to install the wing?
For Octavia A5 The following types of sealants are suitable:
- 3M 08597 โ universal sealant for body work, resistant to vibrations.
- Teroson MS 9399 โ professional sealant for welding seams.
- ABRO WS-904 - a budget option, suitable for temporary fixation.
Apply a thin layer of sealant (2โ3 mm) to the joints of the fender and the body. Avoid excess - this will complicate future dismantling.
What should I do if the wing squeaks after installation?
Creaking usually occurs due to:
- The fender does not fit tightly to the body (check the gaps and tighten the bolts).
- No spacers between metal surfaces (use rubber or plastic washers).
- Friction of plastic elements (treat contact points silicone grease).
If the squeaking does not go away, disassemble the problem area and apply anti-squeak spray (for example, Liqui Moly Kunststoff-Pflege).
Is it possible to drive without a wing?
Technically it's possible, but it's unsafe and illegal. Missing wing:
- Violates body rigidity, which affects controllability.
- Allows moisture and dirt access to spar and strut, accelerating corrosion.
- May cause fine from the traffic police (under Article 12.5 of the Code of Administrative Offenses for malfunctions that threaten safety).
If the wing is damaged but still standing, secure it with zip ties or tape until repair.
