I'm looking at buying an actron CP9575.
I want it to help me check error codes on X5s I'm possibly going to buy and then for maintenance of the car at home.
The question I have is can it read all error codes such as gearbox and say suspension airbag problems or does it only give engine error codes?

This is the only one local auto stores sell as far as I can find so far and need it in the next few days preferably.

Thanks guys*
