Whether you are a weekend DIYer or a dedicated enthusiast, these steps ensure your car stays in top condition. Let’s dive into the mechanics of your BMW’s side mirrors. Following this guide will save you a trip to the dealership and a significant amount of money.
Understanding the BMW 1 Series Mirror Assembly
Before you grab your tools, it is vital to understand what is happening inside the mirror housing. BMW mirrors are designed to be aerodynamic and lightweight, which means they rely heavily on plastic tension clips rather than heavy bolts. This design makes them sleek, but it also makes them susceptible to snapping if you apply pressure in the wrong direction.
The assembly consists of the main mirror motor, the glass element, and the outer shell or “cap.” On most 1 Series models, the cap is held in place by four to five primary clips that bite into the internal frame. Depending on your specific model year, these clips may be accessible only after removing the glass, or they might be reachable by prying the outer edge of the cover itself.
Understanding the “generation” of your car is the first step. The E87 (first generation), F20/F21 (second generation), and the newer F40 (third generation) have slight variations in clip placement. However, the fundamental logic remains the same: release the tension, and the cover slides off. Knowing this layout prevents you from forcing the plastic and causing permanent damage.
Essential Tools for a Clean Mirror Cap Removal
To learn how to remove wing mirror cover bmw 1 series properly, you must use the right equipment. Using a metal screwdriver is the fastest way to chip your paint or shatter the mirror glass. Instead, professional detailers and mechanics rely on specialized non-marring tools that distribute pressure evenly.
- Plastic Trim Removal Kit: These are flat, wedge-shaped tools made of reinforced nylon. They allow you to get behind the plastic without scratching the finish.
- Microfiber Cloths: Placing a cloth between your tool and the car body provides an extra layer of protection for the paintwork.
- Work Gloves: A pair of thin, grippy gloves will protect your hands if the glass happens to break and helps you maintain a firm hold on the slippery plastic.
- Small Flashlight: You will need this to see the internal clips once the glass is tilted or removed.
- Heat Gun or Hairdryer (Optional): In cold weather, plastic becomes brittle. Warming the mirror cover slightly can make the clips more flexible and less likely to snap.
Having these tools ready will make the process much smoother. It also demonstrates the difference between a “hack job” and a professional-grade DIY repair. If you are working on an older E87 model, you might also need a small T10 Torx driver, as some early versions used a single security screw behind the glass.
Safety First: Preparing Your BMW for DIY Work
Safety is often overlooked in minor cosmetic repairs, but it is the most important part of any automotive project. Before you begin, ensure your car is parked on a flat surface with the parking brake engaged. If your BMW has power-folding mirrors, make sure they are in the “out” or “open” position before you start prying.
Another critical step is to adjust the mirror glass using the internal controls. Tilt the glass as far “in” (toward the car window) and “down” as possible. This creates a gap at the top outer corner where you can safely insert your pry tool. If your mirrors are heated, remember that there are thin electrical wires attached to the back of the glass.
If you are working in a cold garage, the plastic clips are at a high risk of breaking. I highly recommend running the car’s heater or using a hairdryer to warm the mirror housing for a few minutes. This simple step makes the plastic significantly more “forgiving.” Taking five minutes to prepare will save you hours of frustration later.
how to remove wing mirror cover bmw 1 series: The Step-by-Step Glass Method
The most reliable way to perform this task is to remove the mirror glass first. This gives you a clear view of the clips and prevents you from flying blind. While it adds an extra step, it is the method used by BMW technicians to ensure nothing breaks during the process.
- Position the Glass: Use the interior mirror switch to tilt the glass toward the car. This exposes the outer edge of the mirror housing.
- Pry the Glass: Insert your widest plastic pry tool into the gap between the glass and the housing. Gently apply outward pressure until you hear a “pop.” This is the circular motor mount releasing the glass.
- Disconnect Wires: Once the glass is loose, do not pull it away quickly. Carefully disconnect the two small wires for the heating element. Set the glass aside in a safe, soft place.
- Locate the Clips: Look inside the housing. You will see several plastic tabs holding the outer cover to the frame. There are usually two at the top and one or two near the bottom.
- Release the Tabs: Use a smaller pry tool or a flat-head screwdriver to gently push the tabs downward or outward. While holding the tab down, use your other hand to pull the mirror cover away from the car.
- Slide the Cover Off: Once the main clips are released, the cover should slide forward and off the assembly. Be careful not to drop it on the pavement.
This method is the gold standard for how to remove wing mirror cover bmw 1 series because it eliminates the guesswork. You can see exactly which clip is holding the cover in place. If you encounter resistance, stop and check if a hidden tab is still engaged. Never use excessive force; the cover should move freely once the clips are clear.
Alternative Method: Removing the Cover Without Pulling the Glass
If you are confident and want to save time, you can remove the cover from the outside. This is often easier on the F20 and F21 models where the clips are positioned closer to the outer seam. However, this method carries a slightly higher risk of marking the plastic edges if you are not careful.
Start by inserting a thin plastic wedge into the seam where the mirror cover meets the black plastic surround. Work your way around the top edge, gently prying as you go. You are looking for the “primary” clip, which is usually located about two inches from the outer tip of the mirror. Once that clip releases, the rest usually follow with minimal effort.
As you pry, use your fingers to maintain constant outward tension on the cover. This prevents the clips from “re-seating” themselves while you work on the next one. This method is popular for those installing aftermarket M-performance caps, as these often come with instructions for external removal. Just remember to use a microfiber cloth to protect the painted surfaces during the process.
Handling Heated and Auto-Dimming Glass
If your 1 Series is equipped with the “Comfort Pack” or higher trim levels, your mirrors might be auto-dimming. This glass is much more expensive than the standard version. It contains a liquid crystal layer that can leak if the glass is bent or cracked during removal. If you see a thick plastic border around your mirror glass, handle it with extreme care.
When disconnecting the wires for auto-dimming mirrors, you will find a small plug rather than two simple spade connectors. Ensure you depress the locking tab on the plug before pulling. Forcing this connector can damage the mirror motor’s wiring harness, leading to an expensive electrical repair. Always prioritize patience over speed when dealing with these high-tech components.
Common Mistakes to Avoid When Handling BMW Mirror Clips
Even experienced mechanics can make mistakes when working with German plastics. The most common error is applying pressure to the center of the mirror glass. Mirror glass is surprisingly flexible but will shatter instantly if localized pressure is applied to the middle. Always pry from the edges, as close to the mounting points as possible.
Another pitfall is forgetting the “hidden” clip. On some 1 Series models, there is a small tab located near the indicator lens. If you pull the cover without releasing this tab, you might snap the mounting point on the indicator itself. Always use a flashlight to inspect the interior of the housing for any secondary fasteners or wires that might be snagged.
Finally, avoid doing this job in direct sunlight or freezing temperatures. Direct sun can make the paint on the cover soft and prone to marring, while the cold makes the plastic brittle. A climate-controlled garage or a shaded area on a mild day provides the best environment for a successful DIY how to remove wing mirror cover bmw 1 series project.
Troubleshooting and Reassembly Tips
Once you have finished your repair or upgrade, reassembly is essentially the reverse of removal, but there are a few tricks to ensure a perfect fit. Before snapping the new cover on, inspect the clips. If you are using aftermarket covers, sometimes the plastic tabs are slightly too thick. A light sanding with fine-grit paper can help them slide into place without excessive force.
Align the cover with the housing and press firmly until you hear a series of clicks. Ensure the gaps between the cover and the mirror frame are even all the way around. If one corner is sticking out, a clip likely hasn’t seated properly. Remove it and try again rather than trying to “bash” it into place.
When reinstalling the glass, don’t forget to reconnect the heating wires. Line up the circular mount on the back of the glass with the motor in the housing. Press firmly in the center of the glass using the palm of your hand until it clicks. Test the mirror’s movement using the interior switch to ensure the motor isn’t obstructed and the glass is secure.
Frequently Asked Questions About how to remove wing mirror cover bmw 1 series
Will removing the mirror cover void my BMW warranty?
Generally, removing a trim piece like a mirror cover does not void your entire vehicle warranty. However, if you break the mirror glass or damage the internal wiring during the process, the repair of those specific parts will not be covered. Always work carefully to avoid unnecessary claims.
Do I need to disconnect the battery?
For a standard mirror cover replacement, you do not need to disconnect the battery. However, if your mirrors have integrated cameras or complex blind-spot monitoring sensors, it is a safe practice to disconnect the negative terminal to prevent any electrical “ghost” codes in the car’s computer system.
Can I paint my new mirror covers myself?
Yes, you can paint them, but for a professional look, you should use a high-quality primer and a color-matched base coat. Many BMW owners prefer to buy pre-painted covers or carbon fiber versions to ensure the finish matches the factory quality exactly.
What should I do if a plastic clip snaps?
If a single small clip snaps, the cover might still stay in place securely with the remaining clips. However, if a major mounting tab breaks, you may need to use a small amount of automotive-grade adhesive or replace the cover entirely to prevent it from vibrating or falling off at high speeds.
Are the mirror covers the same for the 1 Series and 3 Series?
In many cases, yes. The F20 1 Series often shares mirror components with the F30 3 Series. However, you should always verify the part numbers before purchasing replacements, as the internal mounting structures can vary slightly between different body styles.
