Got this now and connected it today, worked 1st time and I didn't have any connection problems with HTC wildfire.
For all those TDi owners it does have exhaust temp displays, at 4 sensor points. The software in the App is brilliant, I have got this set now as a display screen for all 4 points on one view. I'll see what happens when driving next.

But I was reading on the producers forum last night (seems pretty busy!) that the more expensive Scantool.net ones do power save and shut off when the phone disconnects/car engine/electrics are turned off.
