Ε KODA Octavia A7 One of the most popular sedans and station wagons on the Russian market, but even its durable body is not immune to chipping, corrosion and mechanical damage. Particularly vulnerable areas are rapids They are the first to take on blows from road gravel, reagent and curbs. In this article, we will discuss which thresholds are suitable for Octavia A7 (including restyled versions) how to install them correctly and how to handle them for maximum protection.

We analyzed the feedback of owners, the technical characteristics of original and non-original parts, as well as the nuances of installation - from surface preparation to anticorrosion treatment. If you plan to replace the thresholds yourself or want to understand the offers of car service providers, this guide will help to avoid mistakes and save on repairs.

Types of thresholds for the Ε KODA Octavia A7: what are and what are the differences

Thresholds on Octavia A7 They are divided into several categories depending on the material, design and purpose. The main division is original (OEM) and unoriginal (aftermarket). The first are produced by the company Ε KODA or its official suppliers (e.g., Benteler or Magna SteyrThe second is by third-party brands, such as Febi Bilstein, Meyle or Polcar.

Key differences:

  • πŸ”Ή Original thresholds: perfect fit, guaranteed compatibility with body mounts, but high price (from 8 000 to 15 000 rubles per side). Suitable for restoration after an accident or at the dealer's warranty requirements.
  • πŸ”Ή Non-original (analogues): cheaper by 30-50%, but may differ in the thickness of the metal and the quality of welds. Popular with brands Febi (Article 36506) and Meyle (100 421 0003).
  • πŸ”Ή Reinforced thresholds: metal thickness of 1.2-1.5 mm (against 0.8-1 mm in standard). Relevant for off-road or frequent loads (for example, for taxis).
  • πŸ”Ή Plastic liningsThey do not replace metal sills, but protect them from chipping. Installed on double-sided scotch or clips (example: linings) Heko or EGR).

It is worth highlighting repair-insert Threshold fragments for partial repair (for example, when rust in the lower edge). They are used if the main part of the threshold is intact, but local restoration is required. Popular articles: 5E6 807 071/072 (left/right) for the sedan and 5E5 807 071/072 for station wagon Combi.

⚠️ Attention: On restyled versions Octavia A7 (2017–2020) the shape of the back of the threshold at the station wagon has changed. Check compatibility with VIN or directories ETKA/Elcats Unoriginal details may not be suitable!

When to change thresholds: signs of wear and diagnosis

Replacement of thresholds by Octavia A7 It is required not only after an accident, but also with natural wear. The main signs that the metal has become unusable:

  • πŸ” Through corrosion: holes or loose areas visible from the passenger compartment (under the feet of the driver/passenger).
  • πŸ” Bloating of LCPBlisters under paint – a signal of incipient rust under the surface.
  • πŸ” Deformation: dents or bendings after blows that cannot be rectified by a richt.
  • πŸ” Antigravity detachmentIf the protective coating is teared, the metal remains without protection from moisture and salt.

For diagnosis, examine the thresholds from below on the lift or overpass. Pay attention to:

  1. Condition welds in the places of attachment to the spars.
  2. Integrity threshold amplifiers (internal ribs of stiffness).
  3. Availability condensate inside the cavity of the threshold (you can check by tapping metal).

If the rust has gone deep, you will need a complete replacement of the threshold with the cutting of the old and welding the new. With surface corrosion, you can do it. local repairs: cleaning, primer and application of anti-corrosion compounds (for example, Dinitrol 4941 or Tectyl ML).

πŸ“Š How often do you check your corrosion thresholds?
  • Once a season
  • Only before maintenance
  • After strong blows
  • Never checked

Step by step instructions for replacing the thresholds with the Octavia A7

Independent replacement of thresholds is a time-consuming process that requires a welding machine, a Bulgarian and skills in working with metal. If you are not sure of your abilities, it is better to contact the body shop. For those who decided to install with their own hands, we give an algorithm of actions.

Required tools and materials

  • πŸ”§ Grinder with cutting wheel (125 mm).
  • πŸ”§ Welding semi-automatic (wire 0.8 mm).
  • πŸ”§ Safety glasses and gloves.
  • πŸ”§ Putty, primer, paint (to match the body color).
  • πŸ”§ Anti-corrosion composition (e.g. Movi Wax).
  • πŸ”§ A set of keys and heads for dismantling the kits.

Work phases

  1. Removing the old threshold:

    Remove the door seals, plastic linings and wheel from the repair side. Bulgarian carefully cut the welded points along the perimeter of the threshold, without touching the spars. Remove the metal residues and clean the surface to the "bare" metal.

  2. Fitting a new threshold:

    Try on the part to the body, if necessary, cut the edges. Pay attention to this. technological holes For drainage, they must match the original ones.

  3. Welding:

    Grab the threshold at several points, then boil the seams with a solid seam. Use it. spot welding It's a simulation of factory fixtures.

  4. Processing and painting:

    Paint the irregularities, apply the soil, paint in 2-3 layers. After drying, treat the inner cavity of the threshold with anticoric through the technological holes.

Make sure the battery is turned off |Protect the glass and interior from spark |Test the tightness of the weld |Put the soil within 2 hours after welding-->

⚠️ Attention: When welding, do not overheat the metal - this can deform the body panels. Optimal mode: current 80-100 A, wire feed speed 4-5 m / min. After welding, be sure to clean the seams from the slag!
What to do if the threshold is welded crooked?

If after welding the threshold was displaced relative to the body, do not try to "pull" it with a jack - this can damage the spars. It is better to carefully cut the welded seams and redo the work. For accurate fit, use rods and patterns made of cardboard, repeating the contour of the body.

Comparison of materials: steel vs aluminum vs plastic

Thresholds for Octavia A7 They are made of different materials, each of which has pros and cons. Let's look at them in the table:

Material Benefits Disadvantages Cost (overside)
Galvanized steel High strength, resistance to corrosion, long service life (10+ years). Heavy weight (increases the weight of the car), complexity of processing. 6 000–12 000 β‚½
Aluminum Light (40 percent lighter than steel), does not rust, absorbs vibrations well. Low impact resistance, high price, complexity of welding (requires argon). 15 000–25 000 β‚½
Plastic (ABS/polyurethane) Light, not rusting, simple editing (for clips or scotch). It does not protect against serious blows, it can crack in the cold. 1 500–4 000 β‚½
Composite (carbon fiber) Super light, high stiffness, sporty appearance. Very expensive, fragile with spot impacts, the complexity of repair. 30 000–50 000 β‚½

For most owners Octavia A7 remains the best choice galvanized steel It provides a balance of price, strength and corrosion resistance. Aluminum is suitable for tuning versions (for example, Octavia RS), where weight is important. Plastic linings are suitable for temporary protection or as an addition to metal sills.

πŸ’‘

When buying steel sills, check for galvanizing - poor-quality parts can simply be painted "zinc". Check it out: scratch the edge of the threshold with a knife. If under the paint, the silvery layer is zinc, if the gray metal is ordinary steel.

Anti-corrosion treatment: how to protect thresholds for a long time

Even new thresholds require additional protection, especially in Russian conditions with salt on the roads and temperature changes. Consider effective processing methods:

1. Internal protection

The threshold cavity must be treated oil-based anticore. Popular means:

  • πŸ›‘οΈ Dinitrol 4941 - wax composition, forms an elastic film.
  • πŸ›‘οΈ Tectyl ML - oil anticores, penetrates into microcracks.
  • πŸ›‘οΈ Movi Wax - Budget analogue, suitable for self-application.

You need to apply the anticorer through technological holes (usually located at the bottom of the threshold) with a flexible nozzle. Consumption: 1-1.5 liters on both thresholds.

2. External protection

For the outer surface, use:

  • 🎨 Anti-gravel film (for example, 3M Scotchgard) protects against chipping.
  • 🎨 Liquid locker (for example, Body 950) - creates a strong coating, resistant to chemistry.
  • 🎨 Ceramic coating It is expensive, but it provides protection for 2-3 years.

Important: Before applying any protective layer, the thresholds are necessary degrease (for example, White spirit) and dry.

πŸ’‘

The combination of internal anticores (based on wax) and external antigravel film gives maximum protection of thresholds. Octavia A7 from rust and chips.

Tuning Thresholds: How to Improve Appearance and Functionality

Thresholds on Octavia A7 You can not only protect, but also stylize to individual preferences. Let’s take a look at the popular tuning options:

1. LED lighting

Installing LED tapes at the lower edge of the threshold adds a modern look to the car. For Octavia A7 fitting IP67 and a color temperature of 6000K (white light). Example:

  • πŸ’‘ Philips LEDstrip - flexible tape with adhesive base.
  • πŸ’‘ Hella LEDayFlex Modular sections with an aluminum profile.

Connect the lights to side lights Or through a separate switch. Current consumption: 0.5-1 A per meter.

2. Broadening thresholds

For aggressive appearance, the thresholds can be extended by ABS plastic lining or fiberglass. Popular brands:

  • πŸš— Maxton Design - overlays with 3D texture, attached to glue + screws.
  • πŸš— Eibach - sports thresholds for Octavia RS.

3. Powder paint

Alternative to traditional painting powder-spray. It gives a more durable coating, resistant to scratches. Price: from 5 000 rubles for both thresholds.

⚠️ Attention: When installing wide pads, check if it will decrease. ground clearance. On Octavia A7 With a 140mm winding clearance, this can lead to snares on curbs!

Common mistakes when replacing thresholds and how to avoid them

Incorrect replacement of thresholds can lead to accelerated corrosion, creaking or even violation of the geometry of the body. Let’s look at mistakes and ways to prevent them:

  • ❌ Ignoring Threshold Amplifiers:

    Many forget to install the internal ribs of stiffness (article) 5E6 807 101), which causes the threshold to sag over time.

  • ❌ Saving on anticorrosion:

    Applying cheap bitumen anticores (for example, Movil) instead of wax compounds, it causes detachment and moisture accumulation.

  • ❌ Wrong welding:

    A solid seam instead of spot welding increases the risk of corrosion in the places of burning of the metal.

  • ❌ Absence of drainage holes:

    If you do not drill holes for water runoff, condensate will accumulate inside the threshold.

Critical error: the use of ungalvanized thresholds on cars operated in coastal regions or megacities with active use of reagents. In such conditions, the metal rots in 2-3 years, even with regular anticores treatment.

Can I set the thresholds from Octavia A5 to A7?

No, thresholds. Octavia A5 Type 1Z is not compatible with A7 (Typ 5E) due to different body shapes and mounts. Exception - some universal overlays (for example, from Heko), but they are attached to and do not replace standard thresholds.

How much does it cost to replace the thresholds in the service?

The cost depends on the type of thresholds and the scope of work:

  • Replacement of one threshold (original + work): 15,000-25,000 rubles.
  • Local repair (insert + welding): 8000-12,000 rubles.
  • Complete anticor-processing of two thresholds: 3000-5000 rubles.

In Moscow services, prices are 20–30% higher than in the regions.

Which anticor is better for thresholds: wax or oil?

The choice depends on the operating conditions:

  • Wax compounds (for example, Dinitrol) - better for new rapids, as they create an elastic film that does not drain.
  • Oil anticorrosives (for example, Tectyl) - optimal for old rapids with initial corrosion, as they penetrate into microcracks.

For maximum protection, it is recommended to combine both types: first oil, then wax.

Do I need to paint the door after replacement?

Yes, I will! Unpainted metal will begin to rust in a few months. The painting process includes:

  1. A skewer of irregularities.
  2. A grounder (preferably epoxy).
  3. Painting in 2-3 layers with drying between them.
  4. Applying varnish for additional protection.

If the thresholds are galvanized, you can do without soil, but paint is still necessary.

Is it possible to drive with rusty sills?

Technically yes, but it's dangerous.

  • Through corrosion weakens the rigidity of the body, which worsens safety in case of an accident.
  • The rust can go to spars, which will lead to refusal to undergo maintenance.
  • When selling a car, rusty thresholds will reduce its cost by 10-20%.

If your budget is limited, at least handle the thresholds. rust converter (for example, Tsinkar) and cover with anti-grave.
