Anyone with experience and guidance for buying a MUT III tool?
I just had an experience with the yellow error light turning on - probably because of weak 12 V battery. I drove the car for 2-3 days and it locked up. Not possible to start, not possible to charge. The dealer wanted $50 to read the error codes.
I figure I just buy a MUT III tool and then I am able to read the error codes myself and do some early diagnostics.
I found some posts discussing the MUT III tool, but none that shared experience of anyone that bought and used it successfully.
