Firmware compatibility checklist

  • Find the complete software version in the MMI system information screen.
  • Match the full software train, including region and system family, to the product requirements.
  • Confirm whether the product is for MMI 2G, MHS2, MHI2, MHI2Q or a specific MHI3 branch.
  • Check whether maps, activation or other features are excluded; single firmware listings do not include them unless stated.
  • Follow the installation instructions supplied with the selected product.

Do not install firmware from a different software branch

Firmware packages that look similar can target different hardware or software families. Confirm the complete current version before ordering and do not rely only on the Audi A4 model year or screen appearance.

Installation and delivery

Delivery options differ between products and may include digital download or prepared update media. Each product page describes its available options and instructions. Maintain a stable vehicle power supply and do not interrupt an active firmware update.

Frequently asked questions

Do single firmware products include navigation maps?

No. These are firmware-only products unless the individual product page explicitly states otherwise. Maps and their activation are separate or included in selected bundles.

Can I choose firmware based only on the Audi A4 model year?

No. The complete installed software train is needed to identify a compatible firmware package.

Are MHI2 and MHI2Q firmware interchangeable?

They are separate software families. Choose a product that matches the complete system designation shown in your vehicle.

What if I cannot identify my software version?

Use the Audi MMI identification guide or submit your version details through the Check Upgrade service before ordering.
