Okay, wierd one here. This happened to me for the 2nd time last night while i was working on my drag car (vz ute) 1st time it happened it was on my ve probably about 6 months or more ago.

Anyway i could smell and then seen some smoke eminating from my v2 so immediatly unplugged the serial wb,usb & obdi plug from the unit itself and could feel the heat immediatly on the back of the unit near the left hand screw near the 12v inputs (if turning it over to the left, in fact i think i can even see a round mark on the back of the unit where the heat was obviously the most as the plastic now has a perfect circle mark) capacitor maybe?

Anyway the unit still works via the usb/obdi ports and i can still scan. ( havent tested programming or the wb02 or analog ports yet as it was late when i was in the shed)

Now, normally with electronics once you smell burnt parts the equipment is ussually farked and it's time for a replacement. but like i said this is the 2nd time it has happened to me and the unit keeps working (for how much longer i dont know) but over the past few months i've had tremendous trouble trying to scan via my laptop or the software not able to find the ecm when tryign to program, yet after a simple unplug/replug it will work.

Problem there is doesnt do it all the time. (except the scanning which does it 8/10 times)

I'll be honest here and say i havent tried another laptop to see if it's my laptop and it's redirected mydocs playing havok with the software.

As for the smoking/burning problem is it possible for the screws in the back of the case to earth the device out or even get 12v sent down the wb cable? (im using a te2 device)
