Greetings! After some while with my VAS5054A sitting around, I've just managed to get soft V4.0.0 to work stable with USB + BT and on multiple brands. What a pain, all kinds of versions, licenses and hoops to jump through and multiple laptop image re-installs for the result. I'm getting a more recent soft which claims to be an easier install, but we shall see.
Quick question: There's something called OD*S 'engineering' is that needed to stimulate the EOS roof for partial operations or can it be done on the base soft in 'guided fault finding'?
When I get a bit more into this I'm hoping to discover their PIDS and OBD data for roof op stages. Getting VAS5054 to work is a huge challenge for most, but an Arduino module with buffered OBD interface would be just the ticket to control the roof pump and could be easily built by others.
