Hi all,
I've bought a cheap chinese ELM327 v2.1 adapter.
I was trying it using Torque Pro and after 10 minutes on the road that car displayed several error messages (electric break fault, wrong oil level, etc), i stopped the car and turned it off, turned it on and it was saying "Electrical malfunction" or something like that. At this point the car wouldn't start. I disconnected the device, tried a few more times and at some point, everything went back to normal, and the car started and have not displayed any more error messages.
So this adapters CAN induce damage to cars.
The car is a 2004 Renault Scenic 1.5 Diesel.
The adapter as a different mac address of the ones mentioned on this thread: 88:18:56:68:98:EB
I've made two logs:

After connect OBD Car Doctor free was giving me the information in "General Information" that it was a 2.1 device.
What do you think?
