From a quick search, it looks like I have the only Astra on the site - shocker... lol.
For what it's worth, it has the advanced display with two slots for tracking FE, as well as an instant readout which updates 2-3 times per second, as well as an advanced diagnostics screen which can tell me incoming air temp, cabin temp, and coolant temp, maybe some other useful things if I dig, so I shouldn't need a scanguage - just need to learn how to drive!
