So if you are leasing a BMW 135i and want the jb3 but are afraid of warranty issues.. this will clear things up?
And if something goes wrong in my car and I have to take it to the dealer I just take out the jb3, run the scanner, and take it in and I'm fine?
Unrelated: Is it possible to cause problems in your car b/c of the jb3?
Excuse me, I know nothing about cars
