Blue tooth fault code reader

Hi, I am going to purchase a fault code reader and was wondering if anyone had experience with the blue tooth type, any good?

Cheers

I have a 03 td4 and use this one I can monitor most of the engine sensors as far as reading codes not sure as I don't have any issues at the moment and I believe if it isn't broke don't fix it so haven't forced any codes up is unplugging something.

I brought it off of fleabag

Cheers, I think I will get the same model as yours. I just want to identify an intermittent management light issue,

No problem using the blue tooth dangle. I also use Torque on my DROID. Works well reading and clearing faults.
