ŠKODA Octavia A5: How to choose, replace and protect against corrosion

Thresholds ŠKODA Octavia A5 (2004–2013) is one of the most vulnerable parts of the body, which is the first to face corrosion, mechanical damage and wear. Owners of this model often face the problem of rust on the doorsteps after 5-7 years of operation, especially in regions with aggressive winter chemistry. But not everyone knows that the thresholds are Octavia A5 It can not only be restored, but also strengthened, as well as protected from future damage.

In this article we will look at all aspects of working with thresholdsFrom the selection of original and non-original spare parts to step-by-step instructions for replacement and anti-corrosion treatment. You'll know what it is. thresholds are suitable for restyled and pre-facelift versionsHow to distinguish a quality part from a fake, and what methods of protection will prolong the life of your car. And also - we will reveal the secrets of how to save on repairs without loss of quality.

Original and non-original thresholds: articles, sizes and compatibility

Before buying the thresholds for ŠKODA Octavia A5 It is important to decide on the type of part: original (OEM) or analog. Original Thresholds are manufactured under the brand ŠKODA or VW (since the platform PQ35 General), but their price can bite - from 8 000 to 15 000 rubles per side. But they are guaranteed to fit in geometry and fastenings.

Non-original analogues are cheaper (from 3000 to 7000 rubles), but there are risks: poor-quality metal, inaccurate holes under the fastener or poor galvanizing. Among the verified manufacturers stand out Febi, Meyle and Topran Their details are often not inferior to the original in quality.

• 🔧 Original articles:
• Left threshold: 1Z6 807 101/1Z6 807 101 A (pre-facelift), 1Z6 807 101 D (restyle)
• Right threshold: 1Z6 807 201/1Z6 807 201 A (pre-facelift), 1Z6 807 201 D (restyle)
• 🔄 Analogues from Febi: 26300 (left), 26301 (right)
• 🛡️ Strengthened thresholds: Meyle 100 807 0001 (with additional corrosion protection)

Please note: thresholds for Octavia A5 are divided into pre-facelift (2004–2008) and facelift (2009–2013). The main difference is the shape of plastic linings and fasteners. If you put the threshold from the restyle on the pre-facelift, there may be problems with the installation of body kits.

Causes of Wearing Thresholds: Why They Ruin and Rot

Thresholds Octavia A5 There are several factors that can cause corrosion, and not all of them are related to the age of the car. Main reasons:

• ❄️ Reagents and salt: winter chemistry corrodes the factory anti-corrosion coating, especially in the places of chips.
• 💦 Moisture and dirt: The accumulation of water inside the threshold (through drainage holes or cracks) accelerates rusting.
• 🚗 Mechanical damage: Hitting in parking, scratching from shoes or bicycle pedals.
• 🔧 Poor processing in the factory: On some instances, anticor was applied unevenly, especially in hidden cavities.

Particularly vulnerable junction of the threshold with a spar and arch - there's a lot of moisture. If you do not monitor the state of the drainage holes (they are located at the bottom of the threshold), the water will stagnate, and rust will appear in 2-3 years.

⚠️ Attention: If there are bubbles of paint or red spots on the thresholds, this is a signal that the corrosion has already eaten the metal from the inside. In this case, cosmetic repair will not help - you need to replace or cut out rotten areas with welding.

Interesting fact: on Octavia A5 with engines 1.8 TSI and 2.0 TDI The rapids often rot faster than on versions with aspirated motors. This is due to the higher weight of the car and, as a result, a greater load on the body when driving on irregularities.

Step by step instructions for replacing the thresholds on the ŠKODA Octavia A5

Replacing thresholds is a time-consuming process that requires welding and precision. If you don’t have experience, it’s best to trust it to professionals. But if you decide to do it yourself, follow this instruction:

Remove plastic linings (click clips or unscrew screws)

Disconnect the wiring (if the threshold is illuminated)

Clean the old welding with a Bulgarian or chisel

Prepare new thresholds (check the complete set: often the fasteners are sold separately)->

Step 1. Dismantling the old threshold

First, remove plastic linings (they are attached to clips and screws). Then the Bulgarian carefully cut the old threshold, leaving a tolerance of 1-2 cm for future welding. It is important not to damage the spanger and body amplifiers!

Step 2. Fitting a new threshold

We apply a new part to the installation site and check the coincidence of holes under the fastener. If there are differences, we will use a file or a Bulgarian. Nana Octavia A5 Often it is necessary to refine the joints with the arch and the central rack.

Step 3. Welding and anticor

We grab the threshold in several places, then we boil it with a solid seam. After welding, we must treat the seams. primer for metal and apply anti-corrosion composition (for example, Dinitrol 4941 or Tectyl ML). Do not forget about the drainage holes - they need to be cleaned and treated with a sealant.

Step 4. Installation of linings and painting

After the anticory is completely dry, we install plastic linings and paint the threshold in body color. For the perfect result, use spray booth - in the open air can get dust.

Anti-corrosion treatment: how to protect thresholds from rust

Even the new thresholds on Octavia A5 They need additional protection. There are several methods of anticorrosion treatment, and they can be combined for maximum effect:

Processing method	Protection period	Cost (over the threshold)	Pros	Cons
Liquid anticores (Dinitrol, Tectyl)	2–3 years	500–1 500 ₽	It is easy to apply, penetrates into hidden cavities.	Requires reprocessing, can drain
Movie + paraffin	1–2 years	300–800 ₽	Cheap, you can apply it yourself.	Weak protection against mechanical damage
Anti-Eglave Film (3M, Hexis)	5+ years	3 000–6 000 ₽	Protects against chips and scratches	Expensive, hard to glue without experience
Galvanizing (hot method)	10+ years	15 000–25 000 ₽	Maximum protection against corrosion	Expensive, requires removal of the threshold

For Octavia A5 The best option would be a combination. liquid anticores inside the threshold and gravitational. This will protect from rust from the inside, and from mechanical damage.

If your budget is limited, you can get by rust-transducer (for example, Tsinkar). But remember: this treatment should be repeated every 1-2 years.

How to check the quality of anticorrosion treatment?

After applying the anticores, examine the threshold for the lumen - if untreated areas are visible, then the composition is applied poorly. Also check the drainage holes: they should be open but sealed at the edges so that water does not get inside.

Stronger Thresholds: When to Choose and When to Choose

The increased thresholds are relevant to Octavia A5, which are operated in difficult conditions: frequent off-road trips, transportation of goods or installation of a more powerful engine. They are thicker than standard (usually 1.5-2 mm versus 0.8-1 mm) and have additional stiffness ribs.

Where to buy:

• 🏆 Meyle HD: reinforced thresholds with galvanizing, article 100 807 0001.
• 🔨 Febi Bilstein: thresholds with additional protection against corrosion, articles 26300 HD.
• 💰 Sport versions: thresholds with integrated footsteps (e.g., from ABT Sportsline).

Reinforced thresholds are 30-50% more expensive than standard thresholds, but their installation is justified if:

• 🚙 You often drive on dirt roads or curbs.
• 🔧 Planning tuning suspension (for example, installing springs) H&R or shock absorbers KW).
• 🔥 You have a powerful version.RS or vRS) where the body is under heavy loads.

⚠️ Attention: The reinforced thresholds can weigh 2-3 kg more than the standard ones. This will slightly affect the dynamics, but it is worth considering when tuning the suspension.

Repairing thresholds without replacement: when possible and how to do

Not always the thresholds on Octavia A5 They need a full replacement. If the corrosion is superficial or damage is local, you can do it. partial renovation. Here's when it's possible:

• 🔍 Small pockets of rust (up to 5 cm in diameter).
• 🚗 Scratches or chips No through corrosion.
• 🔧 Deformations from light impacts (no scraps of metal).

Step by step repair:

1. We clean the rust to pure metal (Bulgarian or sandblast).
2. Processing. rust converter (for example, Tsinkar).
3. We apply epoxy primer And we put a slap on the bumps.
4. Paint in 2-3 layers with drying between them.
5. Paste anti-gravel film to vulnerable areas.

Use the repair of the holes in the hole. patch-welding or epoxy (if welding is not possible). The latter method is less reliable, but suitable for a temporary solution.

Frequent mistakes when working with thresholds and how to avoid them

Even experienced craftsmen sometimes make mistakes when replacing or repairing thresholds. Octavia A5. Here are the most common:

• 🔥 Poor welding: weak seams lead to the break of the threshold during loading.
• 💧 Closed drainage openings: Water accumulates inside, accelerating corrosion.
• 🎨 Painting without primer: The paint will quickly disintegrate, especially in the places of folding.
• 🔧 Use of incompatible details: The thresholds from pre-facelift to restyle or vice versa.

To avoid problems:

• Check body geometry after welding (use it) laser level Or patterns.
• Apply anticorrosive pre-plastic This will help you to treat all the hidden cavities.
• Use galvanized screws To keep the stains on, to avoid rusting.

If you doute in your power, it is better to contact a specialized body center. In Moscow and St. Petersburg, there are services that are engaged in this. ŠKODA and VW They know all the nuances of the platform. PQ35.

FAQ: Frequently asked questions about ŠKODA Octavia A5 door sills

Can I set the thresholds from Octavia A7 to A5?

No, thresholds. Octavia A7 (platform MQB) are not compatible with A5 (PQ35). The size, mounting and shape are completely different. The only option is to find universal thresholds, but they will have to be greatly refined.

How often do thresholds need to be treated with anticorrosive?

If liquid anticores are used (for example, Dinitrol), treatment must be repeated every 2–3 years. For anti-gravel film or galvanizing, re-treatment is not required, but inspection for damage is recommended once a year.

What to do if the threshold is rusted through?

Cosmetic repairs will not help with through corrosion. Need either cut out the rotten part and weld a patch, or change the threshold completely. A temporary solution is epoxy resin with fiberglass, but this will not last long.

Is it possible to paint the sills without removing the covers?

Technically it is possible, but the quality will be low. Dirt and moisture accumulate under the linings, and if these places are not cleaned, the paint will quickly peel off. It is better to remove the covers, clean them, treat them with anti-corrosion agent and only then paint them.

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

The cost depends on the region and complexity of the work:

• Replacing one threshold: 8 000–15 000 ₽ (with spare part).
• Replacing two thresholds with anticorrosive: 20 000–35 000 ₽.
• Reinforced thresholds + galvanization: up to 50,000 rubles.

In Moscow and St. Petersburg, prices are 20–30% higher than in the regions.
