Purpose and fitment for the BMW E46 body

The presented quarter window glass is designed specifically for installation in the rear left section of the BMW E46 series body. Proper placement on the vehicle guarantees a correct fit with the window frame, seals, and other body components, which is crucial for maintaining airtightness and the proper operation of opening mechanisms.

Thanks to its factory geometry, the glass works with original mounts and guides, which facilitates installation and reduces the risk of additional bodywork modifications. This is particularly important for post-accident repairs, where precise reproduction of the body lines is essential.

Glass characteristics and color

The glass is made of tempered AS2 automotive glass in green. This type of glass provides adequate mechanical strength and resistance to typical operational loads, such as body vibrations or temperature changes. The green tint improves driving comfort by reducing the penetration of sunlight into the cabin and helping to maintain a consistent look for the side window line across the entire vehicle.

Selecting glass with the correct optical specification is important not only from an aesthetic point of view but also for safety – proper transparency and uniformity of the glass affect visibility and prevent image distortion in the mirrors.

Condition, origin, and advantages of using a used part

The item comes from dismantling and is offered as a used BMW quarter window glass. In practice, this means maintaining the original build quality and fitment while reducing repair costs compared to new components. Original glass from dismantling allows you to maintain the visual consistency of the vehicle, which is important both for daily use and for the future resale of the car.

Benefits of using original quarter window glass

Using a factory quarter window glass in a BMW E46 brings a number of practical benefits:

• preservation of original body lines and a consistent look of the vehicle's side section,
• compatibility with factory seals and mounts,
• appropriate optical parameters of AS2 type glass,
• reduction of repair costs while maintaining a high level of fitment.

For body shops and services specializing in the BMW brand, using original glass from dismantling also means more efficient repair execution – without the need to adapt the component to the body.
