This 2006 Audi A6 bulb guide is designed to help you verify the correct bulb size by lighting position, so you can match the right part before you buy. Because Audi used different lighting setups across trims, markets, and body styles, checking the exact location on the car is the best way to confirm fitment.
Use this page as a quick reference for exterior and interior bulbs on the 2006 Audi A6, including headlights, tail lamps, license plate lights, cabin lights, and cargo-area lighting. If you are replacing a single bulb or planning a full refresh, matching the bulb to the correct position helps avoid returns and installation delays.
Fitment can vary by trim, lighting package, and whether the car uses halogen or HID-style headlamps, so always compare the bulb listing to what is installed on your vehicle. Some owners also convert to LED aftermarket bulbs, but not every LED will work correctly in every socket or housing, especially where polarity, heat, or bulb monitoring is involved. Before ordering, remove the old bulb and check the part number, base style, and connector shape whenever possible, since the installed bulb is the most reliable reference for replacement.
The listed high beam bulb for the 2006 Audi A6 is H1. Some versions may also use a combined HID-style setup for both high and low beam, so check the headlamp type on your car before ordering.
For versions listed with a combined headlight bulb, the high beam and low beam use D2S. This is common on HID-equipped cars, but trim and market differences can change the setup.
The rear turn signal bulb is 7507. It is a good idea to confirm the old bulb before replacing it, especially if the car has had previous repairs or aftermarket lamp assemblies.
The back up reverse light bulb is 921. If one side is out, it is often smart to replace both sides at the same time for even light output.
The brake light bulb is 7528. On some A6 setups, the tail light and brake light may share closely related bulb positions, so verify the exact socket location before purchase.
The tail light bulb is 7528. As with the brake light, the exact arrangement can vary by lamp housing and market, so checking the installed bulb is recommended.
The front outer turn signal bulb is 2827, the front inner turn signal bulb is 3457A, and the front side marker bulb is 2827. These positions can differ depending on headlamp design, so match the bulb to the socket location.
The daytime running light bulb is 7506. If you are converting to LED, make sure the replacement is compatible with the housing and any vehicle monitoring system.
The license plate light bulb is 6418. This is a common exterior bulb location, but it is still best to compare the old bulb and the new one before installation.
The dome light bulb and map light bulb are both listed as 64111. Other interior positions on the 2006 Audi A6 may use 2825, 98, or 2821 depending on the location, such as the glove box, door lights, stepwell lights, courtesy lights, and vanity mirror lights.
The trunk or cargo area light can use 2825, 98, and some listings also show alternate options such as 194, 7441 or 6486X depending on the exact setup. Because cargo lighting can vary, checking the original bulb is especially important here.
Trim level, lighting package, market, and body style can all affect bulb fitment. The safest approach is to use the bulb position on the page, then compare it with the bulb currently installed in your car before ordering.
