Updates

Before you update

• Install only the latest version. You do not need to install intermediate versions individually.
• Allow enough time: An update usually takes 12–15 minutes. Packages that include fault code descriptions may take a little longer.
• Use a folder without special characters. The entire file path must be free of special characters such as Ó, ó, É or é. This also applies to the desktop if your Windows username contains these characters. Otherwise, an error message may appear when you open the update file.
• “STREET LEGAL” in the filename means that this software does not support exhaust flap control.
