if you're looking to read fuel pump codes, tuner codes, etc, the actron will not do the job.
I have a canobd2 model 3030. It specifically states in its user manual:
This is a ~$90 (street price) model.
I've only used this on: my old Toyota and a couple of friends' 330ci's.
I have no idea if it really erased hidden codes...
