How to determine glass size by VIN code?

The most reliable way to select a windshield is to use VIN-car code. It contains information about the body, equipment and even options that affect the geometry of the glass. Decoding VIN for Octavia A5:

• 🔹 5–6 characters — body type:
  • 1Z1 - sedan;
  • 1Z5 - station wagon;
  • 1Z3 — liftback (Spaceback).
• 🔹 9 character — verification code (does not affect selection).
• 🔹 10 character - year of manufacture (for example, 5 = 2005, 9 = 2009).
• 🔹 11 character - manufacturer (for Octavia A5 usually M - Mlada Boleslav).

To find out the exact glass article number:

1. Find VIN (under the windshield on the driver’s side or in the vehicle title).
2. Enter it on the site ETKA or VIN-Decoder.
3. In the section Body → Glass find the article number of the original glass.

⚠️ Attention: If your Octavia A5 equipped fingerprint glass (with heated wiper area), the article number will contain the letter H (for example, 1Z1 845 001H). Installing regular glass instead of this will lead to an error B1168 in the comfort block.

Self-replacement: step-by-step instructions

Replacing the windshield with Octavia A5 - a labor-intensive process that requires accuracy. If you are not confident in your abilities, it is better to contact the service. But if you decide to do it yourself, follow these instructions.

Required tools:

• 🔨 A string for cutting glue (or a special knife).
• 🧴 Sealant primer (3M 08609 or equivalent).
• 🖌️ Glass glue (SikaTack Drive, Terostat 8599).
• 🔧 Screwdriver for removing wipers and moldings.
• 🧤 Gloves and masking tape.

Step by step process:

1. Preparation: Remove the wipers (unscrew the nuts M12), remove the moldings and rear view mirror.
2. Cutting out old glass: Pass a string between the glass and the body and carefully cut through the glue. Start from the top corner.
3. Surface cleaning: Remove old glue with a spatula, degrease the surface white spirit.
4. Primer application: Treat the body and new glass with primer (let it sit for 10 minutes).
5. Installing new glass: Apply glue to the body, install the glass and secure with tape for 1-2 hours.
6. Assembly: Install the moldings and wipers, do not close the doors for 6–12 hours (for complete polymerization of the glue).

⚠️ Attention: If your Octavia A5 equipped with a system Lane Assist, after replacing the glass you will need camera calibration! Without this, the system will generate false positives. Calibration can only be done at a service station with a diagnostic scanner (VCDS or ODIS).

What happens if the glass is installed incorrectly?

Leaks can lead to water leaks into the interior and corrosion of the body. It is also possible for airbags to deploy during an accident due to improper load distribution.

Common replacement mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes when replacing a windshield. Here are the most common ones and how to prevent them:

1. Wrong choice of glue

Using cheap glue (eg ABRO) may cause the glass to peel off after 1–2 years. Recommended brands:

• 🔹 SikaTack Drive — dries quickly, suitable for cold weather.
• 🔹 Terostat 8599 - optimal for Octavia A5 with panoramic roof.
• 🔹 3M PU 590 — premium option with a 10-year warranty.

2. Ignoring the primer

The primer improves the adhesion of the adhesive to metal and glass. Without it, the risk of detachment increases in 3–4 times. Apply a thin layer of primer and let it dry for 5-10 minutes.

3. Failure to comply with temperature conditions

The glue polymerizes at a temperature from +10°C to +30°C. If it's colder outside, use a heater or move your work to a warm garage. In hot weather (>30°C), the adhesive may set too quickly, without allowing time to adjust the position of the glass.

4. Incorrect glass alignment

If the glass is installed crookedly, this will lead to:

• 🔴 Uneven wear of wipers.
• 🔴 Distorted view (especially noticeable at speeds >100 km/h).
• 🔴 Leaks in places of loose fit.

Use laser level or special templates for alignment.

5. Forgetting to calibrate sensors

On Octavia A5 with Lane Assist or Light Assist After glass replacement, calibration is required:

• 🔧 For Lane Assist: procedure Basic Setting in the block A5 (Front Camera) through VCDS.
• 🔧 For Light Assist: Reset adaptation in block 09 (Cent. Elect.).
