Purpose and fitment for BMW X5 E70

The presented window has been designed specifically for the BMW X5 E70 model and is installed in the rear right door. This ensures the correct curvature, thickness, and edge shape, which facilitates installation in factory guides and moldings. Proper fitment reduces the risk of leaks, rattles, or excessive vibrations while driving.

Thanks to compliance with BMW factory standards, the component works with original seals, the window lifting mechanism, and door locks without the need for modifications or additional adjustments.

Technical characteristics of the AS3 side window

The AS3 type side window belongs to the Automotive glass category and meets safety and mechanical strength requirements. The appropriate glass structure ensures controlled behavior in the event of damage, and the light transmission properly selected by the manufacturer promotes driving comfort for rear-seat passengers.

The AS3 marking indicates specific glass parameters, including the degree of tint and suitability for side applications, which is important both for protecting the interior from excessive heating and for the privacy of the vehicle's occupants.

Benefits of choosing an original used window

Choosing an original, used side window for the BMW X5 E70 is a solution that combines cost-effectiveness with the preservation of factory quality. A component sourced from the dismantling of a vehicle of the same brand guarantees dimensional and structural compatibility, which is particularly important for glass elements where even minor deviations can cause problems with closing the door.

A used window is also a good choice for those repairing a car after a collision or replacing a damaged element after an act of vandalism. It allows for cost reduction compared to a new part while maintaining the correct functionality and aesthetics of the vehicle.

Professional installation and operation

To fully utilize the potential of this window, installation by an experienced service center is recommended, which will ensure proper positioning in the guides, correct pressure against the seals, and proper alignment with the door frame. Careful installation minimizes the risk of air noise, leaks, or excessive load on the lifting mechanism.

When replacing, it is worth checking the condition of the seals, guides, and the lifting mechanism so that the newly installed window operates smoothly and without interference. Such an approach extends the service life of the entire system and improves the daily comfort of using the car.
