Purpose and compatibility for BMW G20/G21

The offered rear right door is a component from the Doors and door panels category, designed specifically for the BMW 3 Series G20/G21 generation body. The construction is based on BMW's factory technology, which ensures proper alignment with the sills, pillars, and the rear fender on the passenger side. Its placement in the rear section, on the right side of the vehicle, allows for a direct replacement of the damaged panel without the need to interfere with the structural integrity of the body.

Color and paint layer Alpinweiss 3 – 300

The door is finished in the factory color Alpinweiss 3 – 300, also known as Alpine White. This is a characteristic, bright shade used extensively across the BMW range, ensuring visual consistency with other body panels of the same color. Using the original paint color facilitates the refinishing process – in many cases, it limits the scope of painting to the panel connection points, which reduces repair time and the costs of surface preparation.

Characteristics of the used component

This item comes from the used parts segment, meaning it retains the factory construction and geometric parameters specified by the manufacturer. This type of component is particularly useful for post-accident repairs, where maintaining the correct door line relative to the fenders, sills, and roof is crucial. Using a genuine door panel allows for:

• preserving the original structure of the rear section,
• limiting bodywork to the replacement of the complete panel,
• maintaining the correct operation of the lock, hinges, and seals after proper installation.

Application in BMW body repairs

Replacing the complete rear right door in a BMW G20/G21 is a frequently chosen solution for mechanical damage, corrosion, or deformation after a collision. Using an original element from the Doors and door panels group allows for:

• restoring correct gaps between body panels,
• maintaining proper window operation and interior sealing,
• preserving the factory side line characteristic of the BMW 3 Series.

Thanks to its structural compatibility with the G20/G21 body, installation is carried out using factory mounting points, which facilitates the work of the body shop and reduces the need for additional modifications.

Selecting parts by OEM numbers and knowledge about used BMW parts

When selecting a door for a specific BMW 3 Series vehicle, it is crucial to compare the vehicle data with the manufacturer's markings and body specifications. In workshop practice, identification via catalog numbers and interchangeable numbers is often used to confirm full compatibility of the part with a given body version.
