Purpose and fitment for BMW X1 E84

The presented glass is designed as the rear side glazing for the left side of the BMW X1 E84 model. It is responsible for providing proper illumination of the rear cabin, maintaining adequate visibility, and preserving the rigidity of the side body structure. Using an original component helps avoid issues with leaks, body stress, or improper fitment against seals.

The AS2 marking indicates compliance with light transmission and safety requirements, which is important for both driving comfort and regulatory compliance. The glass is prepared for use with factory seals and trim strips used in this model.

Visual characteristics and color

The glass features a black finish, allowing for an aesthetic blend with factory door frames and other windows in the vehicle. This color selection helps maintain a consistent side profile and does not disrupt the original design language of the BMW X1 E84.

The black edge also facilitates masking of adhesive and mounting elements, ensuring that only a uniform, clean glass surface is visible after installation. This solution is particularly beneficial for post-accident repairs, where faithful reproduction of the factory appearance is essential.

Performance parameters and safety

The rear left side glass in the AS2 standard is designed to maintain adequate impact resistance and a controlled breakage pattern in the event of a collision. This reduces the risk of large, sharp shards, which is significant for the safety of rear-seat passengers.

The properly selected thickness and structure of the glass contribute to:

• thermal stability under varying ambient temperatures,
• reduction of stress during body movement on uneven surfaces,
• maintaining proper lateral structural rigidity.

Using an original glass from the same component group as factory glazing helps maintain predictable body behavior during daily operation.

Condition of the item and practical application

The offered glass is a used item, which, in the case of original BMW components, represents a reasonable compromise between quality and repair cost. This type of solution is particularly attractive for post-accident repairs, fleet vehicle renovations, or restoring daily-driven cars to full functionality.

Choosing a used original allows you to maintain compliance with factory specifications while avoiding issues that may arise when using aftermarket replacements of uncertain origin. This is a practical approach to servicing premium cars, where both durability and installation predictability are valued.
