mini elm 327 obd2

have just bought 1 of these for a very expensive payment of Ã,£2.78 with free p/p.
comes with a little disc with all the software for my laptop plus andriod/apple.

reason for buying it,my t5 does not have a temp gauge.bit of backward marketing here by vw as a work m8s t5 55 reg has 1.and something i really do think is essential in every day use of a vehicle.
anyways the reason for buying it is,once plugged in you can monitor REAL time performance of the engine etc.so i can now see exactly what the coolant temp is etc.
this is by far the cheapest way of getting this info,ive read a lot of owners go down the route of changing the clocks,getting the mileage reset and then the clocks reprogrammed for which i have seen banded about a few hundred pounds.

now info i require please,at the moment im leaving it plugged in.so when i enter my phone automatically finds the device,so all i have to do is open up the app and its there(as soon as i turn the engine on).

can i safely continue doing this?
there is a little red light on the unit,cant see it being a problem in draining the battery?but if you peeps know different then please enlighten me.
or could it cause problems with unscrupulous outsiders being able to nick my van??
