Internet is needed only for cloud functionality maintenance functions which you are calling repair functionsQuestion then, in both modes do I need internet to get full functionality ?
Use the Function Chart to follow which functions are implemented in each mode, you need to look around menu's a little more (WiFi/PC)If not, I cannot find a selection to get anywhere to reset the service wrench, read an o2 graph or any of the things the website show being able to do.
Do the autoscan on the Terra, seeing which version it is will be very useful to nail down when Dealers had access to that last firmware releaseI think I got my Terra in May of 13 became a member here in June, so right around June or July of 2013 and I think the original owner bought the Strada in Jul of 13. I was the first to get hooked up to moss for updates at my dealer, and don't know how many they did back then, not many it looks like LOL.
One aspect to note is it is best to hook up a charger/power supply when doing diagnostics, that is what Dealers are supposed to do, in the car pro workshops we use very expensive supplies where both voltage and current are adjustable to suit the vehicle.
For diags on the Terra I have been pulling fuse 2 to eliminate headlight which one Dealer overheated and damaged I noticed
The supply I use is only a 14v 2 amp unit, mine is a DIY job with no fancy rubbish I set up just for the GS and is proving very good on the Terra as well. It was topping up the battery very nicely when doing the beta testing on Sussurf's machine
