This 2001 Audi A6 bulb size guide helps you verify the correct bulb by lighting position, so you can match the right replacement before you order. Because Audi used different lighting setups across trims, body styles, and markets, checking the exact location on the car is the safest way to confirm fitment.
Use this page to identify common exterior and interior bulb types for the 2001 A6, including headlights, parking lights, turn signals, brake lights, reverse lights, license plate lights, and cabin bulbs. The chart is organized by lamp position to make replacement faster and to reduce the chance of buying the wrong bulb.
Fitment can vary on the 2001 Audi A6 depending on trim, lighting package, halogen versus HID headlights, and whether the car has factory or aftermarket conversions. Before buying, compare the bulb in the vehicle with the chart and note the base type, shape, and wattage style if visible. LED replacement bulbs may fit physically but still need to match the correct application and polarity, and some aftermarket upgrades can trigger warning issues or uneven beam patterns. If the car has been modified, always check the installed bulb first, especially for low beams, fog lights, and parking lights.
The low beam headlight bulb listed for halogen-equipped 2001 Audi A6 models is H1. Always confirm your headlight type before ordering, since HID-equipped cars use a different bulb.
The low beam bulb for HID headlight models is D2S. This is different from the halogen setup, so the headlight package on the car matters.
For halogen headlights, the front parking light bulb is 2357A. If the car has HID headlights, the parking light bulb listing is different.
The front parking light bulb for HID-equipped models is 2825, 98. Check the headlight package first because the parking light fitment changes with the setup.
The front turn signal bulb is 2827 for the outer front turn signal. The inner front turn signal bulb is listed as 2357A on this page.
The rear turn signal bulb is 7506. This same bulb type is also listed for the back up reverse light on this page.
The brake light bulb is 7528, and the tail light bulb is also 7528. The rear side marker light is listed with the same bulb type as well.
The license plate light bulb is 6418. This bulb type is also used for several interior and cargo-area positions on the car.
The dome light and engine compartment light are listed as 6411 or 6428, while the map light bulb is 64111. Other interior positions, including the glove box, vanity mirror, trunk or cargo area, stepwell, and courtesy lights, use 6418 or 2825 depending on the location.
The front fog light bulb is listed as H3C or H3, depending on the exact factory setup. Because fog light configurations can vary, it is smart to verify the installed bulb before replacing it.
Audi lighting can vary by market, trim, and body style, so the best approach is to compare the bulb in the car with the chart. If the vehicle has been converted to LED or modified with aftermarket parts, the installed bulb may not match the original factory listing.
Yes, many positions can be upgraded to LED, but the replacement still has to match the correct bulb location and fitment. Some LED bulbs may require polarity checks, and some exterior applications can need additional attention to beam pattern or warning messages.
