The bolt pattern on a 2004 Audi varies by model, but the two most common patterns are 5x112 for the midsize and larger models and 5x100 for smaller models like the A3 and TT.
Bolt pattern by model family
Here's a quick guide to the typical bolt patterns you would find on popular 2004 Audi models. Keep in mind that trim or regional specifications can affect fitment, so always verify with the vehicle’s VIN or official specifications before buying wheels.
- Audi A4 (B6/B7 era, approximately 2000–2008): 5x112
- Audi A6 (C5 era, roughly 1997–2004): 5x112
- Audi S4 (B6/B7 era, roughly 2000–2008): 5x112
- Audi A8 (D3 era, around 2003–2009): 5x112
- Audi TT (8N era, 1998–2006): 5x100
- Audi A3 (8L era, up to 2003) and early 8P models (from 2003–): 5x100
Concluding: In the 2004 Audi lineup, larger sedans and coupes typically used a 5x112 bolt pattern, while smaller models like the TT and A3 used a 5x100 pattern. Always confirm with official specs to avoid fitment errors.
Note on center bore and offset
In addition to the bolt pattern, wheel compatibility depends on the center bore size and offset. These dimensions vary by model and generation, and a mismatch can affect fitment or cause clearance issues. Check the OEM specifications or measure your vehicle’s hubs to ensure proper compatibility.
How to verify the bolt pattern on your 2004 Audi
If you aren’t sure which pattern your car uses, follow these steps to confirm before buying wheels or adapters.
- Look up the vehicle’s specs in the owner's manual or on the manufacturer’s website using the VIN.
- Inspect the factory wheels or the lug nut arrangement to count lugs and measure the bolt circle diameter.
- Ask a dealer or a trusted tire shop to verify the pattern using a lug-pattern gauge or by cross-referencing the VIN.
- When in doubt, avoid mixing patterns from different model years or body styles on the same vehicle.
With the correct bolt pattern confirmed, you can source wheels that fit precisely and avoid costly mistakes.
Summary
For 2004 Audis, the bolt pattern is not uniform across the lineup. The most common configurations are 5x112 for the A4, A6, S4, and A8 families, and 5x100 for the TT and A3 families. Always verify using VIN-specific specifications or official documentation, and don’t overlook center bore and offset when selecting wheels.
