How do I reset my Audi A2's ECU?

I recently had some performance upgrades done on my Audi A2, and I want to reset the ECU to make sure everything is registered properly. How can I do this?

The best way to reset the ECU on an Audi A2 is to disconnect the negative battery cable for at least 10 minutes. This will clear any stored error codes and adaptations.

Another way to reset the ECU is to use a diagnostic tool, such as the VAG-COM. This will allow you to reset the ECU without having to disconnect the battery.

I would recommend double checking with the performance shop that did the upgrades on your Audi A2. They may have a specific procedure for resetting the ECU after upgrades.
