This page covers the 2022 Audi A3 and helps you verify the correct bulb size by lighting position. Whether you are replacing a cabin lamp, a fog light, or a headlight bulb, matching the bulb to the exact location is the safest way to avoid ordering the wrong part.
The 2022 Audi A3 can use different lighting setups depending on trim, market, and body style, so the bulb chart should be checked carefully before buying. Use the listed positions to confirm the fitment for each light on your vehicle, especially if your car has optional lighting equipment.
For the best fitment results, compare the bulb in your car with the chart before placing an order, since trim and lighting package differences can change what is installed. Some 2022 Audi A3 models use halogen-style bulbs in certain positions, while others may have LED or HID-based lighting, and aftermarket conversions can also affect what you see in the housing. If a previous owner has modified the lights, the installed bulb may not match the original factory setup, so checking the actual bulb before purchase is a smart step. This is especially important for headlight and fog light applications, where the wrong bulb type can cause fitment issues or poor beam performance.
