A Broken Mirror on Your Audi A3? Here’s How to Fix It Right.
Hey everyone, it’s Darman. There are few things more frustrating than a damaged side mirror. On a sophisticated car like your 2023 Audi A3, it’s not just an inconvenience—it’s a safety issue and an eyesore that compromises the car’s advanced features. A modern Audi mirror can house heaters, power-folding motors, turn signals, and blind-spot sensors. It’s a complex piece of tech.
Finding the correct driver side mirror assembly fit for a 2023 Audi A3 can feel like a maze of part numbers and features. Do you go with an original part from the dealer? Or can a quality aftermarket part do the job just as well? Don’t worry. In this guide, I’ll walk you through the best options so you can restore your Audi’s looks, safety, and functionality without the guesswork.
First: Check What Your Mirror Has (It’s More Than Just Glass!)
Before you buy anything, you need to know exactly which features your original mirror has. The replacement MUST match these features to work correctly. Pop your head out the door and check for:
- Heated Glass: A small heating element symbol on the glass. Standard on most A3s.
- Power Folding: Does your mirror fold in electronically when you lock the car?
- Turn Signal Indicator: An LED strip on the outside of the mirror housing.
- Side Assist / Blind Spot Warning: An indicator light on the mirror’s surface or inner housing that lights up when a car is in your blind spot. This is a critical safety feature to match.
Full Assembly vs. Glass Only: What Do You Actually Need?
Is only your mirror glass cracked, but the housing, lights, and power functions are all working perfectly? If so, you might not need a whole new assembly. This is the most cost-effective repair.
For Cracked Glass Only: K-Source Fit System Mirror Glass
If the damage is limited to the glass, this is your solution. The K-Source Fit System provides just the mirror glass pre-attached to the plastic backing plate. You simply (and carefully) pry the old broken glass off and snap the new one into place. It’s a quick, affordable fix that restores your visibility without replacing the entire expensive housing.
- Part Type: Mirror Glass with Backing Plate
- Best For: Cracked or damaged glass when the rest of the assembly is intact.
- Pro Tip: Ensure you get the version with the heating elements if your original mirror was heated.

Your Audi Mirror Questions Answered
What’s the difference between OEM and Aftermarket mirrors?
OEM (Original Equipment Manufacturer) is the same part your car was built with. It guarantees a perfect match. Aftermarket parts are made by other companies (like TYC or Dorman) to fit your vehicle. High-quality aftermarket parts can offer excellent value, but the fit and finish might vary slightly from the factory original.
Will my new mirror need to be painted?
Most aftermarket mirror assemblies come with a black or primer-coated cap that is ready to be painted to match your car’s body color. OEM parts may sometimes be available pre-painted in common factory colors for an additional cost. Always check the product description.
Do I need to recalibrate anything after installing a new mirror?
If your mirror only has heat and power-adjust features, usually no calibration is needed. However, if your Audi A3 has Side Assist (blind spot monitoring), the system may require recalibration by a qualified technician with the proper tools to ensure it functions correctly and safely. It’s always best to consult your service manual or a professional mechanic.
Darman’s Final Recommendation
Choosing the right driver side mirror assembly for your 2023 Audi A3 comes down to balancing budget and perfection. For a guaranteed factory-perfect result, nothing beats **Genuine OEM**. For the best balance of high quality and significant cost savings, a reputable aftermarket brand like **TYC** is my top recommendation. And if only your glass is broken, save yourself a lot of money with the **K-Source glass-only** replacement. Whatever you choose, be sure to match the features precisely, and your Audi will be looking and performing its best in no time.
