New side mirror glass for your BMW E46 (ensure you have the correct part number)
Flathead screwdriver or a trim removal tool

Clean cloth
Optional: Adhesive remover (if needed)

Step-by-Step Guide to Replacing the Side Mirror Glass

Follow these steps to safely and effectively replace the side mirror glass on your BMW E46:

Locate the Mirror Housing: First, locate the side mirror you need to replace. Carefully examine the housing for any visible clips or screws holding the mirror in place.
Remove the Mirror Cover: Depending on your E46 model, you might need to remove the entire mirror housing assembly or just the cover. To remove the cover, use a flathead screwdriver or trim removal tool to gently pry it off the housing, working your way around the edges. Be careful not to damage the plastic cover.
Detach the Old Mirror Glass: Once the cover is off, you'll see the old mirror glass secured to the housing. Look for clips or tabs holding the glass in place. Carefully use a flathead screwdriver or a plastic pry tool to release these clips and carefully remove the old glass. Be mindful of sharp edges and handle the glass with caution.
Install the New Mirror Glass: Line up the new mirror glass with the housing, ensuring it fits snugly and securely. Make sure the glass aligns with the housing's grooves. Use a little pressure to snap the new glass into place if necessary.
Re-attach the Cover: Once the new glass is securely installed, put the mirror cover back on. Align the cover with the mirror housing and gently press it back into place, ensuring all clips snap securely. Use a plastic pry tool to help re-attach the cover if needed.
Test the Functionality: After reassembling the mirror, thoroughly test its functionality. Move the mirror up, down, left, and right to ensure it operates smoothly and without any resistance. Adjust the position of the mirror to your preferred angle.

Important Considerations

While replacing the side mirror glass is a relatively straightforward process, consider these critical points to avoid any issues:

Part Number Verification: Before purchasing a new side mirror glass, ensure you obtain the correct part number for your specific BMW E46 model year and trim level. Incorrect parts can lead to fitment issues.
Adhesive Removal: If the old mirror glass was held in place with adhesive, you might need to clean the housing thoroughly before installing the new glass. Use an adhesive remover if necessary to remove any residual adhesive from the housing. Ensure the surface is clean and dry before attaching the new glass.
Professional Assistance: If you are unsure about any part of this process or encounter difficulty with the replacement, it's always best to seek professional assistance from an experienced mechanic.
