Volkswagen ID.4: Glass repair- Introduction

General information

La minated glass windows are composed of 2 glass panes joined by a transparent plastic film. During the manufacture of laminated glass less strain builds up, which means that in the event of damage there are barely any small fragments. In addition, damaged laminated glass panes provide a better visibility.

Glass repairs have the following advantages over renewing:

• Less expensive solution
• Less time-consuming process
• Less environmental impact
• Ingress of air or water, corrosion, poor reception in vehicles with windscreen aerials can be avoided

Tinted, heated or vapourised glass panes, windscreens with sun protection strips and heat-reflecting glass can be repaired.

The tint of the plastic interlayer is retained.

Types of damage

Types of damage to laminated glass that can be repaired under the specified conditions:

Cow's eye (stone chip)

Star-shaped fracture (stone chip)

Important

• Cracks starting from the impact point must not be longer than 50 mm.
• Cracks must not end in the windscreen seal.

Combined fracture (stone chip)

Important

• Cracks starting from the impact point must not be longer than 50 mm.
• Cracks must not end in the windscreen seal

Daisy (stone chip)

Half moon (stone chip)

Crack (scratch)

Important

• No dirt or moisture must have penetrated into the inner area of the crack.
• Cracks with an impact point may be repaired.

Cracks without an impact point may have occurred due to internal strain in the material.

Prerequisites

Impact point

1. Ceramic band

1. Repair area
2. Field of view

1. Window

Important

• Windows -1- may be repaired if damage on the outside and inside are not in the same point.
• The impact point must be in repair area -A-.

The field of vision -B- corresponds to a strip centred on the centre of the steering wheel and bounded at the top and bottom by the windscreen wiper field.

Size

Important

• Diameter -a- of the impact point must be ≤ 5 mm.

When the impact point is larger, the vacuum and pressure cycles cannot be carried out properly.

The larger the impact point, the larger the visual marks may be after the repair.

Important

• The interior of the repair area must be visually inspected.
• Customers must be informed of possible negative effects or reasons if a glass repair cannot be carried out.

Soiling

Important

• If existing dirt is not removed, dirt may still be visible after the glass repair.

Moisture

Important

• To determine moisture inside, the damage must be viewed from all possible angles.
• If a dark area becomes lighter when the viewing angle is changed, there may be moisture inside the defect.
• A glass repair must only be carried out if the moisture has been eliminated.

All vehicles (continued)

If the film compresses and deforms during repair, dark spots are visible after the glass repair.

Preparing glass repair

Special tools and workshop equipment required

• window repair kit - VAS 6092-

Evaluation

• Evaluate whether a glass repair is economically, aesthetically and technically feasible ⇒ Rep. gr. 52 ; Introduction .

Preparing tool

• Make sure that the components of the window repair kit - VAS 6092- are in proper condition.

• Check expiry date of any required materials.

Preparing vehicle

Important

• The vehicle must not be exposed to direct sunlight during the glass repair, especially if the glass repair is carried out outdoors.
•  The work area must be protected from moisture.

• Cover vehicle areas that can be damaged during glass repair.
