Thank you, five stars. On Volkswagen T5 1.9 diesel came up perfectly. It is very easy to adjust.
the obd gauge don't turn off when the engine key is off .Also on toyota corolla 2002 it seems to freeze and won't update the live obd data on the screen so it's useless!
The obd data freezes on the screen and doesnt update live, connected to toyota corolla year 2002 obd protocol iso9141-2.What's more the screen don't turn off when the engine key is off so it drains the car battery!
