I am new to the forum and would like to purchase one of those car diagnostic devices like the OBD 2 to maintain the condition of the car, regularly check the car for errors and further to disable unnecessary errors that might arise in the long run. I am not that keen on cars but just started to get passionate about it; nonetheless, my older brother and I and my younger brother have the following cars:
BMW 3.30i (2004, automatic)
BMW 5.30d (2002, automatic) *mine
BMW 7.30 (2004, automatic).
We would like to buy one of those ODB II so we could regularly do car maintanance and pretty much try to solve our problems (if they arise) and hence pay less to the car-repair people.
I was wondering if anybody is using one of these diagnostic devices and hope to get a feedback on which one to buy?
Thanks in advance.
