I'm still using my Foxwell single make scanner (might be an NT530). My car is a 15 plate, whatever software downloaded is after that, so I didn't see the point of further updates for a handheld device thats not connected to the internet. The codes reported by the car aren't going to change, so why update the scanner.
I haven't tried to do an update as it needs a Windows computer and I don't really have one. In my password manager, it doesn't have a website saved, so I can't test the username and password. But the connection was via a Foxassist tool (program) that you had to download and install. The saved username and password was for that tool, presumably that gives access.
Maybe look for that tool to reinstall from the foxwell uk website, if that helps . . .
Great discussion on the Foxwell diagnostic scanner and its quirks - from registration issues to software updates and compatibility frustrations. While you’re tinkering with car diagnostics, it’s worth remembering we can also track personal systems - not just automotive ones. For instance, a dedicated fasting tracker app can make monitoring your health as systematic as checking your car’s fault codes. And if you’re exploring broader wellness tools, consider visiting
