Not sure on that, I can unlock or lock mine from the app but its not brilliant and i wouldn't want to rely on it. If the data is connected it updates the location on the map. but sometimes it updates the data when you refresh it and sometimes it sticks on when you parked it.
The app is pretty rubbish to be honest:
Tells you a load of stats, Fuel left in the car & range on that fuel (if you drive like an old lady with a sprained ankle)
Doors, Top, Windows,Lights Bonnet and "tailgate" status (closed or open or on or off)
Oil Level
Time till Inspection and Oil change
Any Warnings
And a Theft and Location area, which so far just says OK (and I hope always does)
The location shows where the car is but mine is still on the full Audi connect thing, (normal and Infotainment)
Hopefully the weather will be better this weekend, then i can give it a quick wash and maybe even get the roof down
